ADJUSTING THE MOWER FOR CUTTING
Ensure safety locks are properly engaged before attempting to
service mower. Make all adjustments with the tractor turned off,
key removed and parking brake set. Mower must be on level
ground before making adjustments.
SETTING HEIGHT OF CUT
There are four height adjusters per mowing deck. Each adjuster (located in each corner of the deck) must be
adjusted to the same height to ensure a smooth even cut. In addition, each deck must be adjusted the same so
that a level cut is obtained across the whole cutting width of the mower. Mower cutting height adjustment is made
by turning a 5/8
” nut on top of an acme threaded rod which makes up the height adjuster. A pointer on the side
channel indicates the height against the scale. There are an infinite number of adjustments available from
3/8” to
3 3/8
”. Moving the adjuster up and down moves a side channel that mounts the front and rear rollers. Before
attempting to make height adjustments, the locking bolts on the side channels must be loosened. When the desired
adjustment is made, be sure to tighten the locking bolts to maintain the adjusted height. The height scales at the
back of the deck are set so that the back actually cuts slightly higher, this will provide a better cut, prolong the life
of the blades, and reduce horsepower requirement. This will also make the side channel look uneven, but this is
correct.
