MAINTENANCE
GENERAL
Mowing is accomplished by a series of knives which rotate at high speed on a shaft. The shaft is driven by a
hydraulic motor through a set of drive belts. Belt tension is maintained by a spring-loaded idler pulley.
The cutter unit is mounted to the lift frame by two mounting pins and held in place by a hydraulic cylinder. This
cylinder is used to tilt the cutter unit to allow mowing on an angle and tilting to the vertical position for
transporting.
The cutter unit rides on a large roller assembly. The position of this roller is adjustable and will determine the
cutting height of the knives.

1. Lower cutter unit to ground.
2. Place lifting device (scissors jack, hydraulic
jack) under center of cutter housing.
3. Remove hex nuts, washers and carriage
bolts from bracket at each end of roller. Make
certain that roller bracket is free to move
once the fasteners are removed. A stuck
roller could drop suddenly and cause an
injury.
4. Use lifting device to reposition cutter housing
to desired cutting height. Align bracket holes
with cutterhousing holes, then reinstall
fasteners.
5. Lower cutter unit to ground; then remove
lifting device
