Belt Tension Adjustment
Belt must be properly tensioned at all times to avoid
excessive flopping and slipping. A loose belt will also
cause poor cutting and premature wear.
Check tightness of belt regularly, especially when
working the first few hours.
Always retighten or check belt after 4-8 hours of
operation.
Refer to Figure 3-1:
4. Loosen main pivot bolt.
5. Tighten nut on belt tension bolt until you have a
3/4" deflection using approximately 32 lbs. of force at
midpoint between pulleys. Tighten main pivot bolt.
Refer to Figure 3-2.

Cutting Height
Refer to Figure 3-4:
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".
