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. 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.
DPF Ash Accumulation • When enough ash accumulates, the engine • 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.

Supervisor (Protected Menu) This feature allows the supervisor to set the maximum mowing speed in increments of 5% between 30 and 100%, at which the operator can mow (low range). Refer to Setting the Maximum Allowed Mow Speed (page 36) for the procedure to set the mow speed.
Understanding the Operating Characteristics of the Machine Adjusting the Transport Speed Supervisor (Protected Menu) This feature allows the supervisor to set the maximum transport speed in increments of 5% between 30 and 100%, at which the operator can transport (high range). Practice driving the machine, because it has a hydrostatic transmission and its characteristics are different than many turf-maintenance machines.
Changing Mowing Patterns Change mowing patterns often to minimize a poor after-cut appearance from repeatedly mowing in the same direction. Understanding Counterbalance The counterbalance system maintains hydraulic back pressure on the deck-lift cylinders. This pressure improves traction by transferring the mower-deck weight to the mower-drive wheels. The counterbalance pressure has been set at the factory to an optimal balance of after-cut appearance and traction capability in most turf conditions.
Mowing with Sharp Blades • Measure the air temperature at the front center vent in the headliner. A sharp blade cuts cleanly and without tearing or shredding the grass blades like a dull blade. Tearing and shredding causes the grass to turn brown at the edges, which impairs growth and increases susceptibility to diseases. Ensure that the blade is in good condition and that there is a full sail. Note: The air temperature typically stabilizes at less than or equal to 10°C (50°F).
After Operation After Operation Safety • Clean grass and debris from the cutting units, mufflers, and engine compartment to help prevent fires. Clean up oil or fuel spills. • If the cutting units are in the transport position, use the positive mechanical lock (if available) before you leave the machine unattended. • Allow the engine to cool before storing the machine in any enclosure. g221674 • Remove the key and shut off the fuel (if equipped) Figure 70 before storing or transporting the machine. 1.

Belt Maintenance 2. Servicing the Alternator Belt Service Interval: After the first 10 hours If the deflection is not 10 mm (3/8 inch), loosen the idler pulley mounting bolt (Figure 113). Increase or decrease the compressor belt tension and tighten the bolt. Check the deflection of the belt again to ensure that the tension is correct.
Replacing the Blade-Drive Belt 9. • When properly tensioned, the inside measurement of the extension spring (hook to hook) should be approximately 8.3 to 9.5 cm (3-1/4 to 3-3/4 inch). Service Interval: Every 800 hours The blade-drive belt, tensioned by the spring-loaded idler pulley, is very durable. However, after many hours of use, the belt will show signs of wear. Signs of a worn belt are: squealing when the belt is rotating, blades slipping when cutting grass, frayed edges, burn marks, and cracks.

Note: The caster wheels of all 3 mower decks should remain on the ground when adjusting the counterbalance and with counterbalance applied. g020446 Figure 119 1. Counterbalance adjusting screw g031621 Figure 118 3. Start the engine and let it run for about 2 minutes to purge air from the system. 4. Shut off the engine and check for leaks.
Cutting Unit Maintenance Pivoting (Tilting) the Center Mower Deck to the Upright Position Note: Although not needed, you can pivot (tilt) the center mower deck. 1. Raise the center mower deck slightly off the floor, set the parking brake, and shut off the engine, and remove the key. 2. Remove the hairpin cotter securing the dampers to lift arms (Figure 120). g020969 Figure 121 1. U-bolt g011514 2. Hairpin cotter 3. Pivot the damper toward the deck housing. 4.
Adjusting the Mower-Deck Pitch Adjusting the Wing Mower Decks Measuring the Mower-Deck Pitch Mower-deck pitch is the difference in height-of-cut from the front of the blade plane to the back of the blade plane. Use a blade pitch of 8 to 11 mm (5/16 to 7/16 inch). That is the back of the blade plane is 8 to 11 mm (5/16 to 7/16 inch) higher than the front. 1. Position the machine on a level surface on the shop floor. 2. Set the mower deck to the desired height of cut. 3.
Servicing the Caster Wheels and Bearings Service Interval: Every 800 hours 1. g004737 Figure 124 1. Caster-arm tube Note: Grasp the caster wheel and slide the bolt 2. Bushings 5. Drive the other bushing out of the tube. 6. Clean the inside of the tubes to remove dirt. Remove the locknut from the bolt holding the caster-wheel assembly between the caster fork (Figure 125) or the caster-pivot arm (Figure 126). out of the fork or pivot arm. Installing the Bushings 1.
4. Check the bearings, spacer, and inside of the wheel hub for wear and replace any damaged parts. Blade Maintenance 5. To assemble the caster wheel, push the bearing into the wheel hub. Blade Safety A worn or damaged blade can break, and a piece of the blade could be thrown toward you or bystanders, resulting in serious personal injury or death. Note: When installing the bearings, press on the outer face of the bearing. 6. 7.
Removing and Installing the Mower Blade(s) Replace the blade if it hits a solid object, is out of balance, or if it is bent. Always use genuine Toro replacement blades to ensure safety and optimum performance. 1. 1. Position the machine on a level surface, raise the mower deck, engage the parking brake, put the traction pedal in NEUTRAL, put the PTO lever in the OFF position, shut off the engine, and remove the key from the ignition. 2.
Correcting a Mower-Deck Mismatch to ensure sharpness (Figure 131). The blade remains balanced if the same amount of metal is removed from both cutting edges. When there is mismatch between the blades on a single mower deck, the grass appears streaked when it is cut. You can correct this problem by ensuring that the blades are straight. g000276 1. Park the machine on a level surface. 2. Raise the height of cut to the highest position; refer to Adjusting the Height of Cut (page 26). 3.
Cab Maintenance Cleaning the Cab Important: Use care around the cab seals and lights (Figure 132). If you are using a pressure washer, keep the washer wand at least 0.6 m (2 ft) away from the machine. Do not use the pressure washer directly on the cab seals and lights or under the rear overhang. g028378 Figure 133 In-Cab Air Filter 1. Filter 2. Grate 3. Screw g034330 Figure 132 1. Seal 2. Light 3. Keep wand 0.6 m (2 ft) away. g028379 Figure 134 Rear Cab Air Filter 4.
Cleaning the Cab Pre-Filter The cab pre-filter prevents large debris, such as grass and leaves, from entering the cab filters. 1. Rotate the screen cover down. 2. Clean the filter with water. Important: Do not use a pressure washer. Note: If the filter has a hole, tear, or other damage, replace the filter. 3. Allow the pre-filter to dry before installing it into the machine. 4. Rotate the filter screen around the tabs until the latch locks into the latch-mount assembly (Figure 135).
Storage 10. Preparing the Traction Unit 1. Shut off the engine and remove the key. 2. Thoroughly clean the traction unit, mower decks, and the engine. Important: Do not use high-pressure water near the Info Center or engine-control unit (ECU), as this may cause damage. 3. Check the tire pressure; refer to Checking the Tire Pressure (page 23). 4. Check all fasteners for looseness; tighten as necessary. 5.
