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 the 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. Remove the bolts securing the tailwheel beam in
position and allow the tailwheel to rest at ground
level. Align tailwheel beam between nearest sets
of holes in beam support brackets and reinstall
support bolts on each side of beam. Tighten all
bolts and nuts.
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 tail wheel leaves the ground.
This will allow the mower to follow the contour of
uneven terrain.
6.1 Setting Mowing Height
Note: Install optional check chains when there is a
problem with the hydraulic 3-Point lift maintaining a
set height or when a constant preadjusted cut height
is required. See Check Chains in the Assembly Section
for this accessory.
