Setting Mower Height- Lift Type - (Standard Or Quick Hitch) - Bush Hog BH400 Series Operator's Manual

6.1 Setting Mower Height- Lift Type - (Standard or Quick Hitch)

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. Adjust the mower deck front to rear by
extending or retracting the 3-point top link.
Always set front of deck 3/4" lower than rear for
best performance.
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.
