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“.
