CUTTING HEIGHT ADJUSTMENT
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. A wrench for this purpose is provided. 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 washer under the nut indicates the height against the decal.
There are an infinite number of adjustments available from 1/2” to 4”. Moving
the adjuster up and down moves a side channel that mounts the front and rear
rollers. The height indicator plates at the back of the deck are set 1/4” lower, so
that the back actually cuts 1/4” higher, this will provide a better cut, prolong the
life of the blades, and reduce horsepower requirement.
To make a height adjustment, follow these steps:
1) Loosen the 2 locking bolts on the side channel
2) Loosen the ACME jam nut
3) Turn the 5/8” nut on top of the ACME threaded rod to desired height
displayed on the height indicator plate.
4) Tighten ACME jam nut
5) Tighten the sided channel locking bolts
