Preparation Safety • While mowing, always wear substantial footwear, long trousers, hard hat, safety glasses, and hearing protection. Tie back long hair. Do not wear jewelry. Do not operate the equipment when barefoot or wearing open sandals. This machine meets or exceeds CEN standard EN 836:1997, ISO standard 5395:1990, and ANSI B71.4-2012 specifications in effect at the time of production.
• Remember there is no such thing as a safe slope. • • • • • • • • • • • Reduce the throttle to low idle before stopping Travel on grass slopes requires particular care. To guard against overturning: – Do not stop or start suddenly when going up or downhill. – The machine speed should be kept low on slopes and during tight turns. – Stay alert for humps and hollows and other hidden hazards. – Never mow across the face of the slope, unless the machine is designed for that purpose.
• Use care when checking blades. Wrap the blades • • • • • Keep hands, feet, and clothing away from moving or wear gloves, and use caution when servicing them. Only replace blades. Never straighten or weld them. Keep hands and feet away from moving parts. If possible, do not make adjustments with the engine running. Charge batteries in an open well ventilated area, away from spark and flames. Unplug charger before connecting or disconnecting from battery.

Pedal Locking Latch Product Overview The pedal locking latch (Figure 3) connects the pedals together to engage the parking brake. Controls Note: Determine the left and right sides of the Tilt Steering Lever machine from the normal operating position. Press the lever (Figure 3) down to tilt the steering wheel to the desired position. Then release the lever to lock the adjustment.
Engine Speed Switch Power Point The engine speed switch (Figure 4) has two modes to change the engine speed. By momentarily tapping the switch, the engine speed can be increased or decreased in 100 rpm increments. By holding the switch down the engine will automatically move to High or Low idle, depending on which of the switch is depressed. The power point (Figure 5) is used to power optional electrical accessories. PTO Switch The PTO switch (Figure 4) has two positions: Out (start) and In (stop).

Checking the Planetary Gear Drive Oil Service Interval: Every 400 hours Check the oil level after every 400 hours of operation or if external leakage is noted. Use high quality SAE 85W-140 gear lube as a replacement. 1. With machine on level surface, position the wheel so one check plug (Figure 15) is at the 12 o'clock position and the other is at 3 o'clock position. g011487 Figure 16 1. Check plug 2.
Checking the Tire Pressure Service Interval: Before each use or daily The tires are over-inflated for shipping. Therefore, release some of the air to reduce the pressure. The correct air pressure in the front and rear tires is 172-207 kPa (25-30 psi ). Important: Maintain even pressure in all tires to ensure a good quality-of-cut and proper machine performance. Also, the Automatic Traction Assist will not work properly with improper tire pressure. Do not under-inflate.

Side Cutting Units To adjust the height-of-cut on the side cutting units, add or remove an equal number of spacers from the castor forks, position the castor wheel axles in the high or low height-of-cut holes in the castor forks, and secure the pivot arms to the selected height-of-cut bracket holes.
decal100-5622nc decal100-5623nc Figure 23 Figure 25 3. Push the castor spindle through the castor arm. Install the shims (as originally installed) and the remaining spacers onto the spindle shaft. Install the tensioning cap to secure the assembly. 4. Remove the hairpin cotter and clevis pins from the castor pivot arms (Figure 24). Remove the hairpin cotters and clevis pins securing the damper links to the cutting unit brackets (Figure 26).
Adjusting the Skids The skids should be mounted in the lower position when operating at heights of cut greater than 64 mm (2-1/2 inches) and in the higher position when operating at heights of cut lower than 64 mm (2-1/2 inches). Note: When the skids become worn, you can switch the skid to the opposite sides of the mower, flipping them over. This will allow you to use the skids longer before replacing them. 1. Loosen the screw at the front of each skid (Figure 28). g011493 Figure 29 1. Gage wheel 2.
Front Cutting Unit Setup Matching Height Of Cut Between Cutting Units Rotate blade on each spindle until the ends face forward and backward. Measure from the floor to the front tip of the cutting edge. Adjust 3 mm (1/8 inch) shims on front castor fork(s) to match height of cut to decal (Figure 30); refer to Adjusting the Cutting Unit Pitch. 1. Position blade side to side on outside spindle of both side cutting units. Measure from the floor to the tip of the cutting edge on both units and compare.
Adjusting the Mirrors • The engine has ceased running due to lack of fuel. • Maintenance has been performed upon the fuel Cab model only system components. Rear View Mirror While sitting in the seat, adjust the rear view mirror (Figure 32) to attain the best view out the rear window. Pull the lever rearward to tilt the mirror to reduce the brightness and glare of light. 1. Ensure that the parking brake is set. Remove your foot from the traction pedal and ensure that it is in neutral. 2.
Auto Idle Diesel Particulate Filter Regeneration The machine is equipped with auto idle which automatically idles the engine when all of the following functions are not used, for a pre determined time, previously set in the InfoCenter. 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.
DPF Soot Accumulation • DPF regeneration is a process that heats the DPF to convert the soot to ash. • Over time, the DPF accumulates soot in the soot • In addition to the warning messages, the computer filter. The computer for the engine monitors the soot level in the DPF. reduces the power produced by the engine at different soot-accumulation levels. • When enough soot accumulates, the computer informs you that it is time to regenerate the diesel particulate filter.
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.

engine speed, load on the cutting blades or other implement components, and the importance of the brakes. With Toro Smart Power™, the operator does not have to listen to the engine speed in heavy conditions. Smart Power prevents bogging down in heavy turf by automatically controlling the machine speed and optimizing cutting performance. The brakes can be used to assist in turning the machine. However, use them carefully, especially on soft or wet grass because the turf may be torn accidentally.
Operating Tips • Check to make sure the air conditioning condenser Mow When Grass is Dry • Operate the air conditioner blower at the mid Mow either in the late morning to avoid the dew, which causes grass clumping, or in late afternoon to avoid the damage that can be caused by direct sunlight on the sensitive, freshly mowed grass. • Verify continuous seal between the roof and the fins are clean. speed setting. headliner.

Engine Maintenance Air Cleaner Maintenance • Check the air cleaner body for damage which could cause an air leak. Replace if damaged. Check the whole intake system for leaks, damage or loose hose clamps. Service the air cleaner filter only when the service indicator requires it or every 400 hours (more frequently in extremely dusty or dirty conditions). Changing the air filter before it is necessary only increases the chance of dirt entering the engine when the filter is removed.
