Adjusting the Mower
Determining the length of the upper connector.
After repositioning the mower to the operating position, the stump jumpers should be positioned parallel to the
ground and the suspension frame should be positioned at such a height so the distance “a” is about 11 inches and the
pin is in the middle of the longitudinal opening of the push rod (Drawing 2). Adjustments should be made with the
help of the upper connector and the tractor’s right lift arm brace. In order to ensure the proper operation for the
mower, the suspension frame should be supported by a chain connected with the clevis fastener or its bracket.
Drawing 1: The proper operating mode of the mower.
Drawing 2: The proper alignment of the cotter pin on the engagement rod.
The mower may be positioned at any cut height 32 mm (low), 40 mm, or 44 mm (high). The mower is set to the
middle height of cut. A spacer ring (Position 3 in Drawing 3) may be used to adjust it, which is installed on the
operating drums between the stump jumper’s hub (Position 7 in Drawing 3) and the resistance disk (Position 6 in
Drawing 3).
