Checking The Torque Of Wheel Lug Nuts; Adjusting The Height-Of-Cut - Toro 31598 Operator's Manual

Figure 22
Checking the Torque of Wheel
Lug Nuts
Service Interval: After the first 10 hours
Every 250 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 and rear wheel nuts to 95 to 122
N-m (70 to 90 ft-lb) after 10 hours of operation.
Torque every 250 hours thereafter.

Adjusting the Height-of-Cut

The height-of-cut is adjustable from 25 to 153 mm (1 to
6 inches) in 13 mm (1/2 inch) increments. To adjust the
height-of-cut, 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 adjust the rear
chain (front deck only) to the desired holes. The higher
heights of cut are attained by repositioning the deck caster
arms to the lower set of holes on the deck mounting brackets.
Front Cutting Unit
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 chart
the correct holes for the setting.

2. Castor fork height of cut
mounting holes
Note: When operating at 64 mm (2-1/2 inch) height
of cut or higher, the axle bolt should be installed in
the bottom castor fork hole to prevent grass buildup
between the wheel and the fork. When operating at
heights of cut lower than 64 mm (2-1/2 inch) 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 castor shaft
(Figure 24). and slide the shaft out of the castor arm.
Put 2 shims (1/8 inch [3 mm]) onto the castor shaft
as originally installed. Slide the appropriate number
of 1/2 inch spacers onto the shaft to get the desired
height-of-cut.
Note: The shim washers may be used in any
combination above or below the castor arm hub as
required to achieve the desired height of cut or deck
level.
Refer to the chart (Figure
