Toro 30607A Operator's Manual page 29

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
Front 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 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 18) and slide the spindle out of the
castor arm. Put the 2 shims (3 mm [1/8 inch])
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.
Refer to the following chart to determine the
combinations of spacers for the setting:
4. Push the castor spindle through the front castor
arm. Install the shims (as they were originally
