OPERATION
Working Depth Adjustment
WARNING
Keep all persons away from operator control
area while performing adjustments, service, or
maintenance.
1. Raise the tiller off the ground.
2. Level tiller side to side. Check by measuring from the
forward skid shoe pivot to the ground on each side.
(Figure 8)
3. Adjust, using tractor 3-point arm leveling device.
NOTICE
Keep the front of the tiller parallel to the ground.
4. Place two jack-stands under the tiller rotor shaft.
MEASURE BOTH
ENDS TO GROUND

5. Loosen the 1/2" cap screws that act as the front pivots to
the skid shoes. Remove the 1/2" cap screws (46) that hold
the rear of the skid shoes to the tiller frame.

NOTE: Tillage depth is dependent on ground hardness,
tractor speed, skid shoe setting, and tractor hitch
adjustment. Multiple passes may be necessary to achieve
tillage depth.
Tiller Offset
The RT tillers come with a fixed gearbox offset, so that
the tiller can cover a tractor width larger than its width.
The offset is to the right as sitting in the tractor seat. By
tilling in a clockwise rotation, tire tracks can be reduced
or eliminated. Below is a chart which outlines the tractor
width that can be paired with a tiller.
