4. Push the castor spindle through the front castor arm.
Install the shims (as they were originally installed) and
the remaining spacers onto the spindle shaft. Install the
tensioning cap to secure the assembly.
5. Remove the hairpin cotter and clevis pin securing the
height-of-cut chains to the rear of the cutting unit
(Figure

Note: When using 25 mm (1 inch), 38 mm (1-1/2
inch), or occasionally 51 mm (2 inch) height-of-cut,
move the skids and gage wheels to the highest position.
Wing Cutting Units
To adjust the height-of-cut on the side cutting units, add
or remove an equal number of spacers from the castor
forks, position the castor wheel axles in the high or low
height-of-cut holes in the castor forks, and secure the pivot
arms to the selected height-of-cut bracket holes.
1. Position the castor wheel axles in the same holes in all
of the castor forks
the following chart to determine the correct hole for
the setting.
2. Remove the tensioning cap from the spindle shaft
(Figure
19) and slide the spindle out of castor arm. Put
the two shims (3 mm [1/8 inch]) onto spindle shaft as
they were originally installed. These shims are required
to achieve a level across the entire width of the cutting
units. Slide the appropriate number of 13 mm (1/2
inch) spacers onto the spindle shaft to get the desired
height-of-cut; then slide the washer onto the shaft.
