The engine-speed switch has 2 modes to change the engine speed.

Figure 53

1. Engine-speed switch

• Momentarily tapping the switch increases or decreases the engine speed in 100-rpm increments.

• Pressing and holding the switch down moves the engine speed directly to high or low idle, depending on which side of the switch you press.

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

• The engine has shut off because the machine ran out of fuel.

• Maintenance was performed on the fuel system components.

1. Sit in the operator’s seat, engage the parking brake, and ensure that your foot is off the traction pedal.

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

3. Turn the key to the RUN position.

   Note: The glow-plug indicator displays in the InfoCenter.

4. When the glow indicator shuts off, turn the key to the START position.

   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, check 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.

5. When the engine starts, release the key.

2. Press the PTO switch to the DISENGAGE position.

3. Press the engine-speed switch to the LOW IDLE position.

4. Engage the parking brake.

5. Lower the cutting units.

   Important: Lowering the cutting units relieves the hydraulic load from the system, prevents wear on system parts, and prevents accidental lowering of the cutting units.

6. If the machine was run at full-load operation, allow the engine to idle for 5 minutes.

   Important: Idling the engine for 5 minutes allows the turbocharger to cool down before shutting off the engine. Failure to do so may lead to turbocharger damage.

7. Rotate the key to OFF and remove the key.

8. Wait for all moving parts to stop.

Lock the cutting-unit pivots to prevent the cutting units from rotating downhill when cutting across the face of a hill.

4. Press the traction pedal to drive the machine.

   Important: Be careful when driving between objects so that you do not accidentally damage the machine or cutting units. Use extra care when operating the machine on slopes. Drive slowly and avoid sharp turns on slopes to prevent a rollover.

The turf-compensation spring (Figure 59) transfers the weight from the front roller to the rear roller. This helps to reduce a wave pattern in the turf, also known as marcelling or bobbing.

Important: Make spring adjustments with the cutting unit mounted to the traction unit, pointing straight ahead, and lowered to the shop floor.

1. Make sure that the hairpin is installed in the rear hole in the spring rod (Figure 59).

   Note: When servicing the cutting unit, move the hairpin to the spring-rod hole next to the turf-compensation spring.

   3. Spring rod
   4. Hex nuts

2. Tighten the hex nuts on the front end of the spring rod until the compressed length of the spring is 15.9 cm (6.25 inches); refer to Figure 59.

   Note: When operating on rough terrain decrease the spring length by 13 mm (1/2 inch). Ground following will be slightly decreased.

   Note: The turf compensation setting will need to be reset if the HOC setting or the Aggressiveness of Cut setting is changed.

You can adjust the amount of counterbalance force applied to the rear cutting-units to help compensate for different turf conditions, and to maintain a uniform height of cut in rough conditions or in areas of thatch buildup.

You adjust counterbalance force of each torsion spring to 1 of 4 settings. Each increment increases or decreases the counterbalance force on the cutting unit by 2.3 kg (5 lb).

Note: To remove all counterbalance force, position the long leg of the torsion spring below the capscrew, washer, spacer, and locknut.

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. Insert a tube or similar object over the long leg of the spring, and lift the spring leg to relieve pressure on the spacer (Figure 60).

   Note: Have another person help by lifting and lowering the spring leg.

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 64 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 65 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.

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 66 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.

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. The oil is available in 19 L (5 US gallons) pails or 208 L (55 US gallons) from your authorized Toro distributor.

3. Remove the hydraulic-tank cap from the tank.

4. Remove the dipstick from the filler neck and wipe it with a clean rag.

5. Insert the dipstick into the filler neck; then remove it and check the fluid level.

   The correct hydraulic-fluid level is between the Full mark and the Add mark on the dipstick.

6. If the level is low, add the specified hydraulic fluid to raise the fluid level to the Full mark.

7. Install the dipstick and hydraulic-tank cap to the tank.

Use the following Toro hydraulic filters:

28.4 L (7.5 US gallons); refer to Hydraulic Fluid Specifications

Note: Additional instructions and procedures on backlapping are available in the Toro Sharpening Reel and Rotary Mowers Manual, Form No. 80-300SL.

Wash the machine as needed using water alone or with a mild detergent. You may use a rag when washing the machine.

Important: Do not use brackish or reclaimed water to clean the machine.

Important: Do not use power-washing equipment to wash the machine. Power-washing equipment may damage the electrical system, loosen important decals, or wash away necessary grease at friction points. Avoid excessive use of water near the control panel, engine, and battery.

Important: Do not wash the machine with the engine running. Washing the machine with the engine running may result in internal engine damage.
