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. 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 1-4 hours of
operation and again after 10 hours of operation.
Torque every 200 hours thereafter.
Adjusting the Height-of-Cut
Center Cutting Unit
The height-of-cut is adjustable from 25 to 127 mm (1 to
5 inches) in 13 mm (1/2 inch) increments. To adjust the
2. Check/fill plug
height-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 the
height-of-cut can be changed. Stop the engine and
remove the key after the cutting unit is raised.
2. Position the castor wheel axles in the same holes in all
castor forks. Refer to the following chart to determine
the correct holes for the setting.
1. Tensioning cap
2. Spacers
3. Shims
Note: When operating in 64 mm (2-1/2 inch) height
of cut or higher, the axle bolt must be installed in the
lower castor fork hole to prevent grass buildup between
the wheel and the fork. When operating in height
of cuts lower than 64 mm (2-1/2 inches) and grass
buildup is detected, reverse the machines direction to
pull any clippings away from the wheel/fork area.
3. Remove the tensioning cap from the spindle shaft
(Figure
15) and slide the spindle out of the castor arm.
Put the 2 shims onto the spindle shaft as they were
originally installed. 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.
Note: Refer to the following chart to determine the
combinations of spacers for the setting:
