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. In addition, each deck must be
adjusted the same so that a level cut is obtained across the whole cutting width of
the mower. Mo w e r c u t t i n g h e i g h t a d j u s t m e n t i s m a d e b y t u r n i n g a 5 / 8 " n u t o n

the nut indicates the height against the decal. There are an infinite number of

side rail that mounts the front and rear rollers. Before attempting to make height
adjustments, the locking bolt on the side rail adjacent to the adjuster must be
loosened. When the desired adjustment is made, be sure to tighten the locking
bolt and adjuster jamb nut to maintain the adjusted height. Always adjust so that
the back of the deck cuts slightly higher than the front. Doing this provides a
better cut and requires less horsepower.
