Adjusting The Height Of Cut - Toro Groundsmaster 5910 Operator's Manual

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 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.
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 raising
the mower deck.
3. Position the castor-wheel axles in the same holes in all
castor forks; refer to the chart
the correct holes for the setting.
Note: To prevent grass buildup between the wheel
and the fork, operate the machine at the 64 mm (2-1/2
inch) 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 64 mm (2-1/2
inches) and when you detect grass buildup, reverse the
direction of the machine to pull any clippings away
from the wheel and fork.

4. Install 2 shims onto the caster shaft as originally
installed and 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
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.
5. Push the caster shaft through the front caster arm.

remaining spacers onto the shaft
