Adjustments
Note: Determine the left and right sides of the machine
from the normal operating position.
After the cutting unit is unboxed, use the following
procedures to ensure that the cutting units are adjusted
properly.
1. Check each end of the reel for grease. Grease should be
visibly evident in the reel bearings.
2. Ensure that all nuts and bolts are securely fastened.
3. Position the lift roller to match the suspension.
•
Upper position for standard transport height
•
Lower position for increased transport height
4. Check to make sure that the bedknife and reel are
parallel; refer to Adjusting the Bedknife to the Reel,
page 3.

3. On either end of front side of reel, insert a long strip of
newspaper between the reel and bedknife (Fig. 3).
While slowly rotating the reel forward, turn the
bedknife adjusting knob clockwise, one click at a time,
until the paper is pinched lightly on one end of the reel,
which results in a slight drag when the paper is pulled.
4. Loosen locknuts retaining the left-hand bedbar pivot
housing (Fig. 2).
5. Rotate flange nuts (Fig. 2, inset), on top and bottom of
frame tab, clockwise or counterclockwise to raise or
lower end of bedbar, as required. Do not loosen bottom
flange nut. Tighten flangenuts against frame tab when
desired adjustment is attained.
6. Check adjustments by repeating steps 2 and 3.
7. When light contact on paper is evident at each end of
bedknife, tighten locknuts retaining pivot housing
securely.
