This machine will dynamically brake and stop when you return the traction pedal to neutral.

Note: For smooth deceleration, use your foot to slowly control the traction pedal back to neutral. Do not take your foot off the pedal and allow it to snap back to the neutral position unless you intend to stop quickly.

The machine should come to a complete stop in approximately 3.7 m (12 ft) from the maximum transport speed of 10 mph.

1. On flat, dry pavement, mark out the start and end of 3.7 m (12 ft).

2. Drive the machine at the maximum transport speed of 16 km/h (10 mph) and remove your foot at the start of the 3.7 m (12 ft).

3. Check if the machine stops within 0.6 m (2 ft) of the end mark (3.7 m or 12 ft).

4. Contact your Toro distributor if the stopping distance of the machine is not within 0.6 m (2 ft) of this distance.

Transport Reverse Speed

• If the maximum transport speed set by the supervisor is above 8.0 km/h (5.0 mph), the maximum reverse speed is 8.0 km/h (5.0 mph).

• If the maximum transport speed set by the supervisor is at or below 8.0 km/h (5.0 mph), maximum reverse speed is equal to the transport speed set by the supervisor.

Mowing Reverse Speed

• If the maximum mow speed set by the supervisor is above 6.4 km/h (4.0 mph), the maximum reverse speed is 6.4 km/h (4.0 mph).

• If the maximum mow speed set by the supervisor is at or below 6.4 km/h (4.0 mph), maximum reverse speed is equal to the transport speed set by the supervisor.

This machine displays estimated traction speeds in kilometers per hour (km/h) or miles per hour (mph).

• The instantaneous speed is displayed in the upper left-hand corner of the cruise control and virtual pedal stop screens.

• The traction speeds are estimated, and calibrated to be most accurate at 8.0 km/h (5.0 mph) while mowing. Displayed speeds are accurate when it is 0.8 km/h (0.5 mph) above or below the display speed while driving on dry, flat pavement.

• Contact your authorized Toro distributor if the machine's observed speeds deviate more than 2.4 km/h (1.5 mph) from the displayed speeds.

When starting the machine in cold weather, warm-up mode limits the engine speed to low idle for a short period after the engine is started, preventing potential component damage from operating the machine with cold oil.

A snowflake icon on the InfoCenter screen denotes when warm-up mode is active. Do not operate the machine until after the warm-up period.

• This machine has an automotive-style throttle that is controlled by the traction pedal.

• This machine does not have a separate throttle switch or throttle lever.

• When you remove your foot from the traction pedal, the machine dynamically brakes to a stop.

• The pedal controls are optimized to provide a reactive yet stable response, allowing you to maintain consistent control over rough terrain, while still allowing for quick, smooth braking.

• While transporting, the traction pedal will operate similar to a car and change the engine and traction speed dependent on the traction pedal position.

• When mowing, the engine speed will automatically raise to high idle.

• If the engine is at low idle, performing a function like lifting the cutting units or pressing the traction pedal raises the engine speed to a minimum working speed, providing enough power to efficiently perform the function.

• Limit the machine idle time as recommended for diesel particulate filter (DPF) regeneration. Shut of the machine to prevent extended idling time.

• The maximum speeds set in the PIN protected menu settings are set by the supervisor to limit the machine’s maximum traction speed.

• The achievable traction pedal use, cruise control, and pedal stop traction speeds are all limited by the maximum speeds set in the PIN protected menu.

• If an obstacle is in the way, lift the cutting units or mow around it.

• When transporting the machine between work areas, shut off the PTO, and raise the cutting units to the fully upward position. This allows the traction pedal to operate like a car.

• Always drive slowly in rough areas.

• Never shut off the machine while driving the machine.

This pedal controls the forward and reverse speed of the machine and the dynamic braking when you return it to neutral.

• This machine is equipped with an automotive-style throttle—the engine speed and the machine speed respond to the pedal movement.

• While transporting, the traction pedal will operate similar to a car and change the engine and traction speed dependent on the traction pedal position.

• While mowing, the engine automatically raises to high idle to optimize mowing performance, and the traction pedal only controls traction speed.

• The further you push the pedal forward or reverse, the faster the machine moves.

• To control the machine to a smooth stop while transporting or mowing, use your foot to return the traction pedal to neutral at your desired rate.

• To engage maximum braking, remove your foot from the traction pedal, allowing it to return to neutral. The machine dynamically brakes to a stop.

This traction system allows you to customize the acceleration settings for operator comfort and course conditions. Refer to Understanding the Acceleration Mode for changing the settings.

Figure 27

1. Traction pedal

The virtual pedal stop (VPS) feature allows you to temporarily set a maximum traction speed that is less than the password-protected supervisor maximum traction speed.

To temporarily set the maximum speed of the machine, press the traction pedal fully forward (Figure 27). You can set a separate speed for the mow range and transport range (Figure 28).

• To access this feature, select the InfoCenter middle button from the main screen (Figure 28).

  Note: This feature reverts back to the supervisor maximum speed settings when the key is switched off.

  

  Figure 28

  1. Indicates the maximum traction speed (pedal stop)
  2. This speed is locked out under the protected PIN menu.

• This feature allows you to customize the speed settings for your comfort level, or to customize the speed settings to fit the application.

Whenever the max traction speed is changed via the supervisor max speed settings or Virtual Pedal Stop, the traction pedal is automatically reprogrammed to use the full pedal stroke between neutral and the new max speed. This means the operator gains more precise control of the traction speed at lower maximum speed settings.

This feature determines how quickly the machine changes traction speed when the traction pedal is not in the NEUTRAL position.

Note: If you take your foot off the traction pedal, allowing it to return to the NEUTRAL position while the machine is moving, the braking profile is engaged. The braking profile is always the same and cannot be customized by the acceleration mode feature.

Enter the protected menus in the InfoCenter to change the acceleration mode. The acceleration mode has the following 3 positions:

• Low—least aggressive acceleration and deceleration

• Medium (default)—medium acceleration and deceleration

• High—most aggressive acceleration and deceleration

The counterbalance system maintains hydraulic back pressure on the cutting-unit lift cylinders. The counterbalance system monitors the real-time traction pressure, dynamically changing the lift-cylinder back pressure to optimize traction capability and after-cut appearance. The counterbalance pressure has been set at the factory to an optimal balance of after-cut appearance and traction capability in most turf conditions. Decreasing the counterbalance setting can produce a more stable cutting unit but can decrease the traction capability. Increasing the counterbalance setting can increase the traction capability, but may reduce the quality of the after-cut appearance; refer to Accessing Protected Menus.

The customizable counterbalance setting controls are as follows:

• Low—the most amount of weight on cutting units and the lowest weight on the drive wheels

• Medium—medium weight on cutting units and the drive wheels

• High—the least amount of weight on cutting units and the highest weight on machine drive wheels

You can change the amount of required cutting-unit counterbalance (upward lift) to meet your current mowing conditions.

1. Park the machine on a level surface, lower the cutting decks, turn the key in the switch to the OFF position, and engage the parking brake.

2. Turn the key in the switch to the RUN position.

3. In the InfoCenter Settings Menu, scroll down to Counterbalance.

4. Press the right button to select counterbalance and change between the low, medium, and high settings.

   Note: Once the adjustment has been completed, move the machine to a test area and operate the machine with the new setting. The new counterbalanced setting may change the effective height of cut.

With Smart Power, the operator does not have to listen to the engine speed in heavy load conditions. Smart Power prevents the engine from bogging down in heavy cutting conditions by automatically controlling the machine speed and optimizing cutting performance.

Note: By default, the Smart Power feature is ON.

Important: The fuel system automatically bleeds itself before starting the engine if you are starting the engine for the first time, the engine has shut off due to lack of fuel, or you have performed maintenance on the fuel system.

1. Sit on the seat, keep your foot off the traction pedal so that it is in NEUTRAL, engage the parking brake, and ensure that the PTO switch is in the DISENGAGED position.

2. Turn the key in the switch to the RUN position.

3. When the glow indicator dims, turn the key in the switch to the START position. Release the key immediately when the engine starts and allow it to return to the RUN position.

4. Run the engine at low idle speed until it warms up.

1. Move all controls to NEUTRAL, engage the parking brake, and allow the engine to reach low idle speed.

   Important: Allow the engine to idle for 5 minutes before shutting it off after a full load operation. Failure to do so may engine components.

2. Turn the key in the switch to the OFF position and remove the key.

1. Start the engine, disengage the brake, disengage the PTO switch, and raise the cutting units.

2. Using the traction pedal like an accelerator pedal on a car, drive the machine to the mowing area.

4. Start driving the machine and lower the cutting units only when all cutting units are over the mowing area.

5. Begin mowing the area.

6. When you complete a mowing pass, tap the lower control lever rearward to lift the cutting units before leaving the mowing area.

7. Perform a tear-shaped turn to quickly line up for your next pass.

8. Press the lower control lever to automatically lower all cutting units in the mowing area and continue mowing.

The diesel particulate filter (DPF) is part of the exhaust system. The diesel-oxidation catalyst of the DPF reduces harmful gasses and the soot filter removes soot from the engine exhaust.

The DPF regeneration process uses heat from the engine exhaust to incinerate the soot accumulated on the soot filter, converting the soot to ash, and clears the channels of the soot filter so that filtered engine exhaust flows out the DPF.

The engine computer monitors the accumulation of soot by measuring the back pressure in the DPF. If the back pressure is too high, soot is not incinerating in the soot filter through normal engine operation. To keep the DPF clear of soot, remember the following:

• Passive regeneration occurs continuously while the engine is running—run the engine at full engine speed when possible to promote DPF regeneration.

• If the back pressure in the DPF is too high or a reset regeneration has not occurred for 100 hours, the engine computer signals you through the InfoCenter when reset regeneration is running.

• Allow the reset regeneration process to complete before shutting off the engine.

Operate and maintain your machine with the function of the DPF in mind. Engine load at high idle (full throttle) engine speed generally produces adequate exhaust temperature for DPF regeneration.

Important: Minimize the amount of time that you idle the engine or operate the engine at low-engine speed to help reduce the accumulation of soot in the soot filter.

DPF Soot Accumulation

• Over time, the diesel particulate filter accumulates soot in the soot filter. The computer for the engine monitors the soot level in the DPF.

• When enough soot accumulates, the computer informs you that it is time to regenerate the DPF.

• DPF regeneration is a process that heats the DPF to convert the soot to ash.

• In addition to the warning messages, the computer reduces the power produced by the engine at different soot-accumulation levels.

Engine Warning Messages—Soot Accumulation

Indication Level	Fault Code	Engine Power Rating	Recommended Action
Level 1: Engine Warning	Figure 31 Check EngineSPN 3719, FMI 16	The computer de-rates the engine power to 85%.	Perform a parked regeneration as soon as possible; refer to Servicing the Diesel-Oxidation Catalyst (DOC) and the Soot Filter.
Level 2: Engine Warning	Figure 32 Check EngineSPN 3719, FMI 0	The computer de-rates the engine power to 50%.	Perform a recovery regeneration as soon as possible; refer to Servicing the Diesel-Oxidation Catalyst (DOC) and the Soot Filter.

DPF Ash Accumulation

• The lighter ash is discharged through the exhaust system; the heavier ash collects in the soot filter.

• Ash is a residue of the regeneration process. Over time, the diesel particulate filter accumulates ash that does not discharge with the engine exhaust.

• The computer for the engine calculates the amount of ash accumulated in the DPF.

• When enough ash accumulates, the engine computer sends information to the InfoCenter in the form of an engine fault to indicate the accumulation of ash in the DPF.

• The fault messages indicate that it is time to service the DPF.

• In addition to the warnings, the computer reduces the power produced by the engine at different ash-accumulation levels.

InfoCenter Advisory and Engine Warning Messages—Ash Accumulation

Indication Level	Fault Code	Engine Speed Reduction	Engine Power Rating	Recommended Action
Level 1: Engine Warning	Figure 33 Check EngineSPN 3720, FMI 16	None	The computer de-rates the engine power to 85%.	Service the DPF; refer to Servicing the Diesel-Oxidation Catalyst (DOC) and the Soot Filter

Types of Diesel Particulate Filter Regeneration

Types of diesel particulate filter regeneration that are performed while the machine is operating:

Type of Regeneration	Conditions that cause DPF regeneration	DPF description of operation
Passive	Occurs during normal operation of the machine at high-engine speed or high-engine load	• The InfoCenter does not display an icon indicating passive regeneration.
		• During passive regeneration, the DPF processes high-heat exhaust gasses, oxidizing harmful emissions, and burning soot to ash.
		Refer to Passive DPF Regeneration.
Assist	Occurs because of low-engine speed, low-engine load, or after the computer detects the DPF is becoming obstructed with soot	• The InfoCenter does not display an icon indicating assist regeneration.
		• During assist regeneration, the engine computer adjusts the engine settings to raise the exhaust temperature.
		Refer to Assist DPF Regeneration.
Reset	Occurs every 100 hours	• When the high exhaust-temperature icon is displayed in the InfoCenter, a regeneration is in progress.
	Also occurs after assist regeneration only if the computer detects that assist regeneration did not sufficiently reduce the soot level
		• During reset regeneration, the engine computer adjusts the engine settings to raise the exhaust temperature.
		Refer to Reset Regeneration.

Types of diesel particulate filter regeneration that require you to park the machine:

Type of Regeneration	Conditions that cause DPF regeneration	DPF description of operation
Parked	Occurs because the computer detects back pressure in the DPF due to soot buildup	• When the reset-standby/parked or recovery regeneration icon or ADVISORY #188 displays in the InfoCenter, a regeneration is requested.
	Also occurs because the operator initiates a parked regeneration
	May occur because you set the InfoCenter to inhibit reset regeneration and continued operating the machine, adding more soot when the DPF already needs a reset regeneration	• Perform the parked regeneration as soon as possible to avoid needing a recovery regeneration.
	May result from using the incorrect fuel or engine oil	• A parked regeneration requires 30 to 60 minutes to complete.
		• You must have at least a 1/4 tank of fuel in the tank.
		• You must park the machine to perform a parked regeneration.
		Refer to Parked or Recovery Regeneration.
Recovery	Occurs because the operator ignored requests for a parked regeneration and continued operating the machine, adding more soot to the DPF	• When the reset-standby/parked or recovery regeneration icon or ADVISORY #190 displays in the InfoCenter, a recovery regeneration is requested.
		• A recovery regeneration requires up to 3 hours to complete.
		• You must have at least a 1/2 tank of fuel in the machine.
		• You must park the machine to perform a recovery regeneration.
		Refer to Parked or Recovery Regeneration.

2. Locate the bypass valve under the seat and on the top of the hydrostat (Figure 67).

   

   Figure 67

3. Loosen the valves with 3 turns to allow the oil to bypass internally.

   Note: Because the fluid is bypassed, the machine can be moved slowly without damaging the transmission.

4. Locate the brake release manifold near the front right tire and behind the hydraulic tank (Figure 68).

   

   Figure 68

   1. Pump mechanism on the brake manifold
   2. Black knob

5. Insert the long end of a ratchet or similar object, hold the black knob in on the manifold, and pump the manifold 3 times. As soon as there is substantial resistance when pumping the brake is released.

   Important: Do not pump the manifold after it does not pump easily. Damage could occur if the manifold is pumped too much.

   Note: Once the pressure is built up in the manifold, the brake will be released for approximately 60 minutes. If needed after 60 minutes, release the brake again by pumping the manifold.

6. Push or tow the machine.

7. Set the brake by pulling the black knob out or starting the engine.

   Note: The brake automatically resets when you start the engine and you do not need to pull the black knob out.

8. Close the bypass valves. Torque the valves to 11 N∙m (5 to 8 ft-lb).

   Important: Ensure that the bypass valves are closed before you start operating the machine. Running the engine with an open bypass valve causes the transmission to overheat.

1. Park the machine on a level surface.

2. Engage the parking brake.

3. Disengage the PTO.

4. Move the lower mow/raise control to the MOW position.

5. Shut off the engine, and remove the key.

  Note: Ensure that the grease groove in each roller mount aligns with the grease hole in each end of the roller shaft. To help align the groove and hole, there is also an alignment mark on 1 end of the roller shaft.

Check the whole intake system for leaks, damage, or loose hose clamps. Do not use a damaged air filter.

Service the air-cleaner filter only when the service indicator requires it. Changing the air filter before it is necessary only increases the chance of dirt entering the engine when the filter is removed.

Important: Make sure that the cover is seated correctly, seals with the air-cleaner body, and the rubber outlet valve is in a downward position—between the 5 o’clock and 7 o’clock positions when viewed from the end.

Figure 79

This Operator’s Manual contains more detailed fuel and fuel system maintenance information than the Yanmar^® engine Owner’s Manual, which is a general-purpose reference relating to fuel and fuel maintenance.

Ensure that you understand that the fuel system maintenance, fuel storage, and fuel quality require your attention to avoid downtime and extensive engine repairs.

The fuel system has extremely tight tolerances due to the emissions and control requirements. Diesel fuel quality and cleanliness is more important for the longevity of today’s high-pressure common rail (HPCR) fuel-injection system used on diesel engines.

Important: Water or air in the fuel system will damage your engine! Do not assume that new fuel is clean. Ensure that your fuel is from a quality supplier, store your fuel correctly, and use your fuel supply within 180 days.

Important: If you do not follow the procedures for fuel filter replacement, fuel system maintenance, and fuel storage, the engine fuel system could fail prematurely. Perform all fuel system maintenance at the specified intervals or whenever the fuel is contaminated or its quality is poor.

Appropriate fuel storage is critical for your engine. Proper maintenance of fuel storage tanks is often overlooked and leads to the contamination of fuel delivered to the machine.

• Acquire only enough fuel that you will consume within 180 days. Do not use fuel that has been stored for more than 180 days. This helps eliminate water and other contaminates in the fuel.

• If you do not remove the water from the storage tank or machine fuel tank, it can lead to rust or contamination in the storage tank and fuel system components. Tank sludge developed by mold, bacteria, or fungus restricts flow and clogs the filter and fuel injectors.

• Inspect your fuel storage tank and machine fuel tank regularly to monitor the fuel quality in the tank.

• Ensure that your fuel comes from a quality supplier.

• If you find water or contaminants in your storage tank or machine fuel tank, work with your fuel provider to correct the problem and perform all fuel system maintenance.

• Do not store diesel fuel in tanks or canisters made with zinc-plated components.

1. Clean the area around the fuel-filter head (Figure 85).

   

   Figure 85

2. Remove the filter and clean the filter head mounting surface (Figure 85).

   Note: Use a clean cloth to clean the filter head.

3. Lubricate the filter gasket with clean lubricating engine oil; refer to the engine owner's manual for additional information.

4. Install the dry filter canister by hand until the gasket contacts the filter head, then rotate it an additional 1/2 turn.

5. Prime the filter and the lines to the high pressure pump; refer to Priming the Fuel System.

6. Start the engine and inspect for leaks around the filter head again.

In addition to the listed service interval, drain and clean the tank if the fuel system becomes contaminated or if you are storing the machine for an extended period. Use clean fuel to flush out the tank.

Prime the filter and the lines to the high pressure pump; refer to Priming the Fuel System.

Inspect the fuel lines for deterioration, damage, or loose connections.

Replace any deteriorated clamps or hoses.

Note: Prime the fuel system if you replace any fuel lines; refer to Priming the Fuel System.

If engine faults , , or in the InfoCenter (Figure 86) display in the InfoCenter, clean the soot filter using the steps that follow:

Figure 86

1. Refer to the Engine section in the Service Manual for information on disassembling and assembling the diesel-oxidation catalyst and the soot filter of the DPF.

2. Refer to your authorized Toro distributor for diesel-oxidation catalyst and the soot filter replacement parts or service.

3. Contact your authorized Toro distributor to have them reset the engine ECU after you install a clean DPF.

Prime the fuel system after the following scenarios:

• Replacing the fuel filter.

• Draining the water separator after each use or daily.

• Running out of fuel.

• Replacing a fuel hose or open the fuel system for any reason.

To prime the fuel system, perform the following steps:

Important: Do not use the engine-starter motor to crank the engine for fuel-system priming.

1. Ensure that fuel is in the fuel tank.

2. Perform the following steps to prime the filter and the lines to the high-pressure pump to prevent wear or damage to the pump:

   1. Cycle the key to the ON position for 15 to 20 seconds.

   2. Cycle the key to the OFF position for 30 to 40 seconds.

      Note: This allows the ECU to power down.

   3. Cycle the key to the ON position for 15 to 20 seconds.

   4. Inspect for leaks around the filter and hoses.

   5. Start the engine and inspect for leaks.

Perform the following tasks to service the battery:

The coolant reservoir is filled at the factory with a 50/50 solution of water and ethylene glycol base extended-life coolant.

Important: Use only commercially available coolants that meet the specifications listed in the Extended Life Coolant Standards Table.Do not use conventional (green) inorganic-acid technology (IAT) coolant in your machine. Do not mix conventional coolant with extended-life coolant.

Coolant Type Table

Extended Life Coolant Standards

Important: Coolant concentration should be a 50/50 mixture of coolant to water.

• Preferred: When mixing coolant from a concentrate, mix it with distilled water.

• Preferred option: If distilled water is not available, use a pre-mix coolant instead of a concentrate.

• Minimum requirement: If distilled water and pre-mix coolant are not available, mix concentrated coolant with clean drinkable water.

The cooling system is filled with a 50/50 solution of water and permanent ethylene glycol antifreeze. The capacity of the cooling system is 9.5 L (10 US qt).

1. Check the level of coolant in the expansion tank (Figure 93).

The reservoir is filled at the factory with high-quality hydraulic fluid. Check the level of the hydraulic fluid before you first start the engine and daily thereafter; refer to Checking the Hydraulic-Fluid Level.

Recommended hydraulic fluid: Toro PX Extended Life Hydraulic Fluid; available in 19 L (5 US gallon) pails or 208 L (55 US gallon) drums.

Note: A machine using the recommended replacement fluid requires less frequent fluid and filter changes.

Alternative hydraulic fluids: If Toro PX Extended Life Hydraulic Fluid is not available, you may use another conventional, petroleum-based hydraulic fluid having specifications that fall within the listed range for all the following material properties and that it meets industry standards. Do not use synthetic fluid. Consult with your lubricant distributor to identify a satisfactory product.

Note: Toro does not assume responsibility for damage caused by improper substitutions, so use products only from reputable manufacturers who will stand behind their recommendation.

High Viscosity Index/Low Pour Point Anti-wear Hydraulic Fluid, ISO VG 46

Note: Many hydraulic fluids are almost colorless, making it difficult to spot leaks. A red dye additive for the hydraulic fluid is available in 20 ml (0.67 fl oz) bottles. A bottle is sufficient for 15 to 22 L (4 to 6 US gallons) of hydraulic fluid. Order Part No. 44-2500 from your authorized Toro distributor.

Important: Toro Premium Synthetic Biodegradable Hydraulic Fluid is the only synthetic biodegradable fluid approved by Toro. This fluid is compatible with the elastomers used in Toro hydraulic systems and is suitable for a wide-range of temperature conditions. This fluid is compatible with conventional mineral oils, but for maximum biodegradability and performance, the hydraulic system should be thoroughly flushed of conventional fluid.

2. Move the cutting unit into position in front of the traction unit.

3. Slide the deck-carrier frame onto the lift-arm pivot pin and secure it with the lynch pin (Figure 102).

4. Install the hydraulic motor to the deck (Figure 101). Make sure that the O-ring is in position and not damaged.

5. Grease the spindle.

Inspect the front roller for wear, excess wobble, or binding. Service or replace the roller or components if any of these conditions exist.

The rotary deck comes from the factory preset at 5 cm (2 inches) height of cut and blade rake of 7.9 mm (0.310 inch). The left and right heights are also preset to within ± 0.7 mm (0.030 inch) of the other.

The cutting deck is designed to withstand blade impacts without deformation of the chamber. If a solid object is struck, inspect the blade for damage and the blade plane for accuracy.

Replace the blade if it hits a solid object, is out of balance, or is bent. Always use genuine Toro replacement blades to ensure safety and optimum performance.

1. Park the machine on a level surface, raise the cutting unit to the transport position, engage the parking brake, shut off the engine, and remove the key.

   Note: Block or lock the cutting unit to prevent it from accidentally falling.

2. Grasp the end of the blade using a rag or thickly-padded glove.

   Figure 106

   1. Blade bolt
   2. Anti-scalp cup

4. Install the blade, anti-scalp cup, and blade bolt and tighten the blade bolt to 115 to 149 N∙m (85 to 110 ft-lb).

   Important: The curved part of the blade must be pointing toward the inside of the cutting unit to ensure proper cutting.

   Note: 7After striking a foreign object, torque all spindle-pulley nuts to 115 to 149 N∙m (85 to 110 ft-lb).

1. Raise the cutting deck to the transport position, turn the key in the ignition switch to the OFF position, and engage the parking brake.

2. Block the cutting deck to prevent it from falling accidentally.

3. Examine the cutting ends of the blade carefully, especially where the flat and curved parts of the blade meet (Figure 107).

   Note: Since sand and abrasive material can wear away the metal that connects the flat and curved parts of the blade, check the blade before using the machine.

4. If wear is noticed (Figure 107), replace the blade; refer to Removing and Installing the Cutting-Unit Blade(s).

   Danger

   If the blade is allowed to wear, a slot will form between the sail and flat part of the blade (Figure 107). Eventually a piece of the blade may break off and be thrown from under the housing, possibly resulting in serious injury to yourself or bystanders.

   • Inspect the blade periodically for wear or damage.

   • Always replace a worn or damaged blade.

   

   Figure 107

   1. Cutting edge
   2. Sail
   3. Wear/slot/crack

5. Inspect the cutting edges of all blades. Sharpen the cutting edges if they are dull or nicked. Sharpen only the top of the cutting edge and maintain the original cutting angle to make sure that it is sharp (Figure 108).

6. If dull or nicked, sharpen only the top cutting edge while maintaining the original cutting angle (Figure 108).

   Note: The blade will remain balanced if the same amount of metal is removed from both cutting edges.

   

   Figure 108

   1. Sharpen at this angle only

7. To check the blade for being straight and parallel, lay the blade on a level surface and check its ends.

   Note: Position the ends of the blade slightly lower than the center, and the cutting edge lower than the heel of the blade. This blade produces a good quality of cut and requires minimal power from the engine. By contrast a blade that is higher at the ends than the center, or if cutting edge is higher than the heel, the blade is bent or warped and must be replaced.

   

   Figure 109

   1. Cutting edge
   2. Heel

8. Install the blade, sail facing toward cutting deck, with the anti-scalp cup and blade bolt. Torque the blade bolt to 115 to 149 N∙m (85 to 110 ft-lb).
