ADJUSTMENTS (cont.)
•
To increase the clearance between the cutter bar and the
blades, loosen the lower nut 1/4 turn and then tighten the upper
nut 1/4 turn. Adjust each side of the mower equally until a
0.003” clearance is obtained (Figure 8).
• To adjust the roller, tilt the mower forward and loosen the
knobs on each roller at least two full turns and move the roller
to the desired position. Both roller knobs must be in the same
relative position and firmly seated in the notch.
Paper Test
1. Push the handle of the mower forward and let it rest on the
ground. (The roller will be off the ground.)
2. Using paper as a gauge, insert a strip of quality 0.003” thick
paper (writing paper approximately 2” wide x 6” long be-
tween the cutter bar and the blades as show in (Figure 9).
Correct cutter bar clearance should pinch, but not cut the pa-
per.
3. Perform this test in at least three different points along the
cutter bar.
*NOTE: To eliminate any play or looseness before adjusting the
cutter bar, make certain the bolt and the trunnion which are
threaded into the cutter bar are tight.
