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 to 207 kPa (25 to
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. Replace worn or damaged tires
with genuine Toro tires that are correctly sized for this
machine.
Checking the Torque of the Wheel Nuts
or Bolts
Service Interval: After the first 10 hours
Every 200 hours
WARNING
Failure to maintain proper torque of the wheel nuts
could result in failure or loss of wheel and may
result in personal injury.
Torque the front wheel nuts and rear bolts to 115
to 136 N-m (85 to 100 ft-lb) after 1 to 4 hours of
operation and again after 10 hours of operation.
Torque every 200 hours thereafter.

Adjusting the Height of Cut

Front Cutting Unit
You can adjust the height of cut from 25 to 127 mm (1 to 5
inches) in 13 mm (1/2 inch) increments. To adjust the height
2. Check/fill plug
of cut on the front cutting unit, position the castor wheel
axles in the upper or lower holes of the castor forks, add or
remove an equal number of spacers from the castor forks,
and secure the rear chain to the desired hole.
1. Start the engine and raise the cutting units so that you
can change the height of cut. Stop the engine and
remove the key after you raise the cutting unit.
2. Position the castor-wheel axles in the same holes in all
castor forks (Figure

2. Spacers
3. Shims
Note: When operating at the 64 mm (2-1/2 inch)
height of cut or higher, install the axle bolt in the lower
castor-fork hole to prevent grass buildup between the
wheel and the fork. When operating in heights of cut
lower than 64 mm (2-1/2 inches) and grass buildup is
detected, reverse the machines direction to pull any
clippings away from the area of the wheel and fork.
3. Remove the tensioning cap from the spindle shaft
(Figure 15) and slide the spindle out of the castor arm.
4. Put the 2 shims onto the spindle shaft as they were
originally installed.
Note: These shims are required to achieve a level
across the entire width of the cutting units. Slide the
appropriate number of 13 mm (1/2 inch) spacers (refer
to the chart below) onto the spindle shaft to get the
desired height-of-cut; then slide the washer onto the
shaft. Refer to the following chart to determine the
combinations of spacers for the setting:
