Important: Use only ultra-low sulphur diesel fuel. Fuel with higher rates of sulfur degrades the diesel oxidation catalyst (DOC), which causes operational problems and shortens the service life of engine components.Failure to observe the following cautions may damage the engine.

• Never use kerosene or gasoline instead of diesel fuel.

• Never mix kerosene or used engine oil with the diesel fuel.

• Never keep fuel in containers with zinc plating on the inside.

• Do not use fuel additives.

1. Park the machine on a level surface, lower the cutting units, shut off the engine, and remove the key.

2. Using a clean rag, clean the area around the fuel-tank cap.

3. Remove the cap from the fuel tank (Figure 34).

   

   Figure 34

   1. Fuel-tank cap

4. Fill the tank until the level is to the bottom of the filler neck with fuel.

5. Install the fuel-tank cap tightly after filling the tank.

   Note: If possible, fill the fuel tank after each use. This minimizes possible buildup of condensation inside the fuel tank.

Important: Bleed the fuel system if any of the following situations have occurred:

• The engine has ceased running due to lack of fuel.

• Maintenance has been performed upon the fuel system components.

1. Remove your foot from the traction pedal and ensure that the pedal is in the NEUTRAL position.

   Note: Ensure that the parking brake is engaged.

2. Move the engine-speed switch to the LOW IDLE position.

3. Turn the ignition key to the RUN position.

   Note: The glow indicator will light.

4. When the glow indicator dims, turn the ignition key to the START position.

5. Release the key immediately when the engine starts and allow it to return to the RUN position.

6. Adjust the engine speed.

   Important: Do not run the starter motor more than 15 seconds at a time or premature starter failure may result. If the engine fails to start after 15 seconds, turn the key to the OFF position, recheck the controls and procedures, wait 15 additional seconds, and repeat the starting procedure.

   When the temperature is less than -7°C (20°F), the starter motor can be run for 30 seconds on then 60 seconds off for 2 attempts.

   Caution

   Contact with moving parts could result in injury.

   Shut off the engine and wait for all moving parts to stop before checking for oil leaks, loose parts, and other malfunctions.

Important: Allow the engine to idle for 5 minutes before shutting it off after a full-load operation. This allows the turbocharger to cool down before shutting off the engine. Failure to do so may lead to turbocharger trouble.

Note: Lower the cutting units to the ground whenever you park the machine. This relieves the hydraulic load from the system, prevents wear on system parts, and also prevents accidental lowering of the cutting units.

1. Return the engine speed to low idle.

2. Move the PTO switch to the OFF position.

3. Engage the parking brake.

4. Rotate the ignition key to OFF.

5. Remove the key from the switch to prevent accidental starting.

• 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 36 Check EngineSPN 3719, FMI 16	The computer de-rates the engine power to 85%.	Perform a parked regeneration as soon as possible; refer to Parked or Recovery Regeneration.
Level 2: Engine Warning	Figure 37 Check EngineSPN 3719, FMI 0	The computer de-rates the engine power to 50%.	Perform a recovery regeneration as soon as possible; refer to Parked or Recovery Regeneration.

• 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 38 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 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.

• Passive regeneration occurs as part of normal engine operation.

• While operating the machine, run the engine at full-engine speed and high load when possible to promote DPF regeneration.

• The engine computer adjusts engine settings to raise the exhaust temperature.

• While operating the machine, run the engine at full engine speed and high load when possible to promote DPF regeneration.

Figure 46

• The high exhaust-temperature icon displays in the InfoCenter (Figure 46).

• The engine computer adjusts engine settings to raise the exhaust temperature.

  Important: The high exhaust-temperature icon indicates that the exhaust temperature discharged from of your machine may be hotter than during regular operation.

• While operating the machine, run the engine at full engine speed and high load when possible to promote DPF regeneration.

• The icon displays in the InfoCenter while the reset regeneration is processing.

• Whenever possible, do not shut off the engine or reduce engine speed while the reset regeneration is processing.

  Important: Whenever possible, allow the machine to complete the reset regeneration process before shutting off the engine.

Setting the Inhibit Regen

   1. Oil cooler/radiator

   Important: Cleaning the oil cooler/radiator with water will promote premature corrosion damage to components and compact debris.

5. Close the rear screen and secure it with the latch.

Adjust the service brakes when there is more than 13 mm (1/2 inch) of free travel of the brake pedal, or when the brakes do not work effectively. Free travel is the distance the brake pedal moves before braking resistance is felt.

1. Park the machine on a level surface, lower the cutting units, engage the parking brake, shut off the engine, and remove the key.

2. Disengage the locking latch from the brake pedals so that both pedals work independently of each other.

3. To reduce free travel of the brake pedals, tighten the brakes as follows:

   1. Loosen the front nut on the threaded end of the brake cable (Figure 117).

      

      Figure 117

      1. Brake cable

   2. Tighten the rear nut to move the cable backward until the brake pedals have 0 to 13 mm (0 to 1/2 inch) of free travel.

      Note: Make sure that there is no brake tension when the pedal is released.

   3. Tighten the front nuts after the brakes are adjusted correctly.

Check the condition and tension of the belts (Figure 118) after every 100 operating hours.

1. Park the machine on a level surface, lower the cutting units, engage the parking brake, shut off the engine, and remove the key.

2. Proper tension will allow 10 mm (3/8 inch) deflection when a force of 45 N (10 lb) is applied on the belt midway between the pulleys.

3. If the deflection is not 10 mm (3/8 inch), loosen the alternator mounting bolts (Figure 118).

   

   Figure 118

4. Increase or decrease the tension of the alternator belt and tighten the bolts.

5. Check the deflection of the belt again to ensure that the tension is correct.

The reservoir is filled at the factory with approximately 28.4 L (7.5 US gallons) of high-quality hydraulic fluid. Check the level of the hydraulic fluid before the engine is first started and daily thereafter.

The recommended replacement fluid is Toro Premium All Season Hydraulic Fluid (available in 5-gallon pails or 55-gallon drums. See parts catalog or Toro distributor for part numbers).

Alternative fluids: If the Toro fluid is not available, other conventional, petroleum-based fluids may be used, provided that they meet all of the following material properties and industry specifications. Check with your oil supplier to see whether the fluid meets these specifications.

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

The proper hydraulic fluids must be specified for mobile machinery (as opposed to industrial plant usage), multiweight-type, with ZnDTP or ZDDP anti-wear additive package (not an ashless-type fluid).

Important: The ISO VG 46 Multigrade fluid has been found to offer optimal performance in a wide range of temperature conditions. For operation in consistently high ambient temperatures, 18° C (65° F) to 49° C (120° F), ISO VG 68 hydraulic fluid may offer improved performance.

Premium Biodegradable Hydraulic Fluid-Mobil EAL EnviroSyn 46H

Important: Mobil EAL EnviroSyn 46H 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 fluids, but for maximum biodegradability and performance the hydraulic system should be thoroughly flushed of conventional fluid. The fluid is available in 19 L (5 US gallon) containers or 208 L (55 US gallon) drums from your Mobil Distributor.

Important: 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 (2/3 fl oz) bottles. A bottle is sufficient for 15 to 22 L (4 to 6 US gallons) of hydraulic fluid. Order part 44-2500 from your Authorized Toro Distributor.

1. Park the machine on a level surface, lower the cutting units, shut off the engine, and remove the key.

5. Ensure that the filter mounting area is clean.

6. Screw the filter on until the gasket contacts the mounting plate; then tighten the filter an additional 1/2 turn.

7. Start the engine and let it run for about 2 minutes to purge air from the system.

8. Shut off the engine and check for leaks.

Park the machine on a level surface, lower the cutting units, engage the parking brake, shut off the engine, and remove the key.

Inspect the hydraulic lines and hoses daily for leaks, kinked lines, loose mounting supports, wear, loose fittings, weather deterioration, and chemical deterioration. Make all necessary repairs before operating.

Note: When backlapping, the front units all operate together, and the rear units operate together.

1. Park the machine on a level surface, lower the cutting units, engage the parking brake, shut off the engine, and move the PTO switch to the OFF position.

2. Unlock and raise the hood to expose the controls.

3. Make initial reel-to-bedknife adjustments appropriate for backlapping on all cutting units which are to be backlapped; refer to the cutting unit Operator's Manual.

4. Select either front, rear, or both backlap levers to determine which units to backlap (Figure 122).

5. Start the engine and run at low idle speed.

   Danger

   Changing the engine speed while backlapping may cause the reels to stall.

   • Never change the engine speed while backlapping.

   • Only backlap at low idle engine speed.

   Danger

   Contact with the cutting units could cause personal injury.

   Be certain that you are clear of the cutting units before proceeding.

6. With the mow-speed limiter in the MOW position, move the PTO switch to the ON position.

7. Press the lift switch to start the backlapping operation on the designated reels.
