Before starting the machine each day, perform the Each Use/Daily procedures listed in Daily Maintenance Checklist.

Important: The fuel system automatically bleeds itself when any of the following situations occur:

• You are starting a new machine for the first time.

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

• Maintenance has been performed upon the fuel system components.

1. Sit on the seat, keep your foot off the traction pedal so that it is in NEUTRAL, engage the parking brake, set the engine-speed switch to the MIDDLE position, and ensure that the Enable/Disable switch is in the DISABLE position.

2. Remove your foot from the traction pedal and make sure that the pedal is in the NEUTRAL position.

3. Turn the key to the RUN position.

4. When the glow indicator dims, turn the key to the START position. Release the key immediately when the engine starts and allow it to return to the RUN position. Allow the engine to warm up (without load), then move the throttle control to the desired position.

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

2. Turn the key to the OFF position and remove it from the switch.

To ensure optimum performance of the parking-brake system, burnish (break in) the brakes before use. Set the forward traction speed to 6.4 km/h (4 mph) to match the reverse traction speed (all 8 spacers moved to the top of the mow-speed control). With the engine at high idle, proceed forward with the mow-speed-control stop engaged and ride the brake for 15 seconds. Proceed backward at full reverse speed and ride the brake for 15 seconds. Repeat this 5 times, waiting 1 minute between each forward and reverse cycle to avoid overheating the brakes; refer to Adjusting the Parking Brakes.

Note: Cutting grass at a rate that loads the engine promotes DPF regeneration.

1. Move the machine to the job site and align the machine outside the cutting area for the first cutting pass.

2. Ensure that the PTO switch is set to the DISABLE position.

3. Move the lever for the mow-speed limiter forward.

4. Press the throttle-speed switch to set the engine speed to HIGH IDLE.

5. Use the joystick to lower the cutting units to the ground.

6. Press the PTO switch to prepare cutting units for operation.

7. Use the joystick to raise the cutting units off the ground.

8. Begin moving the machine toward the cutting area and lower the cutting units.

   Note: Cutting grass at a rate that loads the engine promotes DPF regeneration.

9. When you complete the mowing pass, use the joystick to lift the cutting units.

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

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 48 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 49 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 50 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.

Reset Regeneration

Caution

The exhaust temperature is hot (approximately 600°C (1,112°F) during DPF regeneration. Hot exhaust gas can harm you or other people.

• Never operate the engine in an enclosed area.

• Make sure that there are no flammable materials around the exhaust system.

• Never touch a hot exhaust system component.

• Never stand near or around the exhaust pipe of the machine.

Figure 58

• The high exhaust-temperature icon displays in the InfoCenter (Figure 58).

• 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.

Periodic Reset Regeneration

If the engine has not completed a successful Reset, Parked, or Recovery regeneration in the previous 100 hours of engine operation, the engine computer will attempt to perform a reset regeneration.

Setting the Inhibit Regen

Reset Regeneration Only

Note: If you set the InfoCenter to inhibit regeneration, the InfoCenter displays ADVISORY #185 (Figure 59) every 15 minutes while the engine requests a reset regeneration.

Figure 59

A reset regeneration produces the elevated engine exhaust. If you are operating the machine around trees, brush, tall grass, or other temperature-sensitive plants or materials, you can use the Inhibit Regen setting to prevent the engine computer from performing a reset regeneration.

Important: When you shut off the engine and start it again, the inhibit regen setting defaults to OFF.

Note: If INHIBIT REGEN is set to ON, the InfoCenter displays ADVISORY #185 (Figure 62). Press button 3 to set inhibit regeneration setting to OFF and continue with the reset regeneration.

Figure 62

Note: If the engine exhaust temperature is too low, the InfoCenter displays ADVISORY #186 (Figure 63) to inform you to set the engine to full throttle (high idle).

Figure 63

Note: When the reset regeneration completes, the high exhaust-temperature disappears from the InfoCenter screen.

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 can 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). You can position the springs at the back side of the first spring actuator to remove all counterbalance (fourth position).

Note: To remove all counterbalance force, position the long leg of the torsion spring above the shouldered stud.

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

2. Insert the long end of the counterbalance spring into a tube or similar object, and pivot the spring around the shouldered stud to the desired position (Figure 84).

   

   Figure 84

   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 12.7 cm (5 inches) for 5-inch cutting units or 15.9 cm (6.25 inches) for 7-inch cutting units (Figure 87).

   Note: When operating on rough terrain, decrease the spring length by 12.7 mm (1/2 inch). This slightly decreases the ground following.

To achieve a consistent, high quality of cut and a uniform after-cut appearance, adjust the reel speed as follows:

1. In the InfoCenter, under the settings menu, enter the blade count, mow speed, and HOC to calculate the proper reel speed.

2. If further adjustments are required, in the settings menu, scroll down to the F Reel RPM, R Reel RPM, or both.

3. Press the right button to change the reel-speed value.

   Note: As you change the speed setting, the display continues to show the calculated reel speed based on blade count, mow speed and HOC, but the new value is also be displayed.

   Note: You may need to increase or decrease the reel speed to compensate for varying turf conditions.
