SETTING THE MOWER
Properly setting the cutting height is essential for efficient and safe operation. A properly set mower will make a
more uniform cut, distribute clippings more evenly, require minimal tractor work, and follow the contour of uneven
terrain. NOTE: Avoid very low cutting heights, striking the ground with the blades gives the most damaging shock
loads and will cause damage to the mower and drive. Blades contacting the ground may cause objects to be
thrown out from under the mower deck. Always avoid operating the mower at a height which causes the blades to
contact the ground.
OPS-U- 0010
Never work under the Implement, the framework, or any lifted component
unless the Implement is securely supported or blocked up to prevent sudden
or inadvertent falling which could cause serious injury or even death.
(SG-14)
Cutting Height Adjustment (Figure 4-7 & Table 4-1)
The mower comes with four 1” spacers and one 1/2” spacer attached to each caster assembly. The height adjustment is from
1-1/2” to 6” cutting height in 1/2” increments.
1. Raise the mower off the ground using the tractor 3-point lift allowing the Caster Wheels to clear the ground enough for removal.
SECURELY BLOCK THE MOWER IN THIS POSITION.
The mower can fall from hydraulic system failure. To avoid serious injury or death, securely
support the mower before working close to or underneath.
2. Remove the retaining pin securing caster wheel in pivot tube and remove the caster wheel and spacers.
3. Place spacers on the pivot shaft of the caster wheel that will allow you to achieve the desired cutting height, See (Table 4-1).
4. Reinstall caster wheel in pivot tube with height adjusting spacers on the bottom. Place the un used spacers on the pivot shaft
on top and reinstall the retaining pin.
5. Repeat these step for all caster wheels making sure all are adjusted to the same height.
