6. SETTING THE MOWER
Properly setting the mower 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.
1. Park the tractor and mower on level ground.
2. Using the 3-point hitch control lever, position the
front of the mower with its side skids 1” less off the
ground than desired cut height. For example, for a
3” cut, position the skids 2” from the ground. Set
the 3-point control lever stop at this position to
maintain this height when raising and lowering the
mower.
3. Shut down the tractor and remove the key.
4. Level the mower deck front to rear by extending or
retracting the 3-point top link.
5. Level the mower side to side by manipulating one
lower lift arm length. On most tractors, at least
one of the lift arms is designed to allow for
manipulation of its length. Shortening or extending
will allow for deck leveling from side to side.
6. Securely block up the mower at this height.
7. Holding wheel and yoke assembly up, remove
quick-lock pin from the top of guage wheel spindle.
Position full length spacers and half spacer as
required. All spacers on top of spindle tube allows
for approximately 1” cutting height. Adjustment
range from 1” to a maximum of 4-1/2” in 1/2”
increments.
8. Extend the tractor’s top 3-point link so that when
lifting the mower, the front of the deck will raise 2
to 2½" before the rear guage wheels leave the
ground. This will allow the flexible hitch to pivot
and follow the contour of uneven terrain.
