then slide the w asher onto the shaft.
R efer to the follo wing c har t to deter mine the

4. Push the castor spindle through the front
castor ar m. Install the shims (as they w ere
originally installed) and the remaining spacers
onto the spindle shaft. Install the tensioning
cap to secure the assembly .
5. R emo v e the hair pin cotter and clevis pin
securing the height-of-cut c hains to the rear of
the cutting unit ( Figure 16 ).

6. Mount the height-of-cut c hains to the desired
height-of-cut hole ( Figure 17 ) with the clevis
pin and hair pin cotter .

Note: W hen using 1 inc h (25 mm), 1-1/2
inc h (38 mm), or occasionally 2 inc h (51 mm)
height-of-cut, mo v e the skids and g ag e wheels
to the highest holes .
W ing Cutting Units
T o adjust the height-of-cut on the side cutting
units , add or remo v e an equal n umber of spacers
from the castor forks , position the castor wheel
axles in the high or lo w height-of-cut holes in the
castor forks , and secure the pi v ot ar ms to the
selected height-of-cut brac k et holes .
1. P osition the castor wheel axles in the same
holes in all of the castor forks ( Figure 18 and
Figure 20 ). R efer to the follo wing c har t to
deter mine the cor rect hole for the setting .
2. R emo v e the tensioning cap from the spindle
shaft ( Figure 18 ) and slide the spindle out of
castor ar m. Put the tw o shims (1/8 inc h [3
mm]) onto spindle shaft as they w ere originally
installed. T hese shims are required to ac hiev e
a lev el across the entire width of the cutting
units . Slide the appropriate n umber of 1/2
inc h spacers onto the spindle shaft to g et the
desired height-of-cut; then slide the w asher
onto the shaft.
