OPERATION
7.1 Setting Mower Height
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 positioning bracket to the support
brackets and allow the tailwheel to rest at
ground level. Align beam and positioning
brackets holes with closest set of holes in
support brackets and reinstall bolts securing
the beam in position. 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.
NOTE: Install optional check chains when there is
a problem with the hydraulic 3-Point lift maintaining
a set height or when a constant pre-adjusted cut
height is required. See Check Chains in the
Assembly Section for this accessory.
