Checking The Torque Of The Wheel-Lug Nuts; Adjusting The Height Of Cut - Toro Groundsmaster 5900 Operator's Manual

Checking the Torque of the
Wheel-Lug Nuts
Service Interval: After the first 10 hours
Every 250 hours
WARNING
Failure to maintain the proper torque of the
wheel nuts could result in failure or loss of a
wheel, and may result in personal injury.
Torque the front and rear-wheel nuts to 135
to 150 N·m (100 to 110 ft-lb) after 10 hours of
operation. Torque the nuts every 250 hours
thereafter.

Adjusting the Height of Cut

You can adjust the height of cut from 25 to 153 mm (1
to 6 inches) in 13 mm (1/2 inch) increments. To adjust
the height of cut, position the caster-wheel axles in
the upper or lower holes of the caster forks, add or
remove an equal number of spacers from the caster
forks, and adjust the rear chain (front deck only) to the
desired holes.
Adjusting the Front Mower Deck
1. Start the engine and raise the mower decks so
you can change the height of cut.
2. Shut off the engine and remove the key after the
mower deck is raised.
3. Position the caster-wheel axles in the same
holes in all of the caster forks; refer to the chart
(Figure 33) to determine the correct holes for
the setting.
Note:
To prevent grass buildup between the
wheel and the fork, operate the machine at the
76 mm (3 inches) height of cut or higher and
install the axle bolt in the bottom caster-fork
hole. When operating the machine at a height
of cut lower than 76 mm (3 inches) and when
you detect grass buildup, reverse the direction
of the machine to pull any clippings away from
the wheel and fork.

2. Spacers (6)
3. Shims (2 top and 2 bottom)
5. Slide the appropriate number of spacers onto
the shaft to get the desired height of cut.
Note:
Refer to the chart to determine the
combinations of spacers for the setting
33).
Note:
You may use the shims in any
combination above or below the caster-arm hub
(as required) to achieve the desired height of
cut or deck level.
6. Push the caster shaft through the front caster
arm.
7. Install the shims (as originally installed) and the
remaining spacers onto the shaft
