Belt Tension Adjustment
Belt must be properly tensioned at all times to avoid
excessive flopping and slipping. Loose belt will also cause
poor cutting and premature wear.
Check tightness of the belt regularly, especially when
working the first few hours.
Always retighten or check belt after 4-8 hours of operation.
Refer to Figure 2-2.
1. Loosen main pivot bolt.
2. Tighten nut on the belt tension bolt until you have a
3/4” deflection midpoint between pulleys. Tighten
main pivot bolt. Refer to Figure 2-3.

Cutting Height
Refer to Figure 2-4:
Cutting height can be adjusted with the upper 3-point hitch
link.
Maximum cutting height of 2 3/8” is achieved when the
discs are parallel to the ground. Adjustment of cutting
height is achieved by altering the cutter bar tilt angle. This
is done by varying the upper 3-point hitch link length until
desired cutting height is achieved. Shorten the upper
3-point hitch link to lower and lengthen to raise.
To minimize blade and disc wear, improve grass regrowth
and get maximum nutritive value from the crop, minimum
cutting height should never be adjusted less than 1 1/4“.
