Tractor Top Link Adjustment
When the cutting height is set, adjust tractor top link until mower top link attachment point (A), Figure 4, is aligned vertically with mower hitch pin (B). The front tires of the mower will lift off the ground before the rear tires when the unit is raised. This will allow the mower to follow the ground contour.

RDC54 Only
The RDC54 has two mower hitch plate attachment points (D). It may be necessary to change the mower hitch plate attachment point to obtain proper tire clear- ance and/or lift height.
Front Caster Wheel Interference Check
IMPORTANT
■Do not operate tractor and mower until this interference check has been performed. If you change tractors, you must perform the check for that mounting.
Perform this check with all of the spacers and springs above the caster wheel arm. This will place the caster wheels in their highest position and provide the lowest cutting height for the mower.
1.Raise mower with tractor hydraulics to 16" at dimension C, Figure 5, or maximum height of tractor lift, whichever is less.
2.Pivot both front caster wheels forward and check that there is clearance between caster wheels and tractor tires.

Front Roller (Optional)
The caster wheels effectively reduce scalping in most cases. However, you may encounter areas where the caster wheels and/or side skids drop into depressions and allow center of the mower to contact ground and scalp. An optional front roller may be installed to mini- mize scalping. See page 40.
Operating Technique
CAUTION
Stop power unit and implement immediately upon striking an obstruction. Dismount power unit, using proper procedure. Inspect and repair any damage before resuming operation.
Power for operating the mower is supplied by the trac- tor PTO. Operate PTO at 540 rpm. Know how to stop tractor and mower quickly in an emergency.
If mower becomes plugged causing belt to slip for over two seconds, follow these steps:
1.Maneuver equipment into a previously cut area and allow mower to clear accumulated material.
2.Continue running at least two minutes, allowing pulleys to cool. Stopping the mower when in contact with a very hot pulley will bake and ruin belt.
Proper ground speed will depend upon the terrain, the height, and type and density of material to be cut.
Normally, ground speed will range from 2 to 5 mph. Tall dense material should be cut at a low speed; thin
Always operate tractor PTO at 540 rpm to maintain proper blade speed and produce a clean cut.
