Height-of-Cut Adjustment (Floating Cutting Unit)
Overview of Procedure:
1. Adjust reel to bedknife contact
2. Level rear roller to reel
3. Final height-of-cut adjustment using gauge bar.
STEP 1 - Adjust Reel to Bedknife Contact
A. Adjust reel to bedknife contact on all cutting units.
(Re
fer to Adjusting Reel To Bedknife Contact).
STEP 2 - Level Rear Roller to Reel
B. Start engine and lower the cutting units onto a flat
sur
face such as a piece of 3/4" or 1 “ plywood (at
least 20" x 30" in size). Stop engine and remove key
from switch. Lock cutting units in the fixed position,
by loosening the jam nut on lockout pin (Fig. 6) and
screwing pin into hole in pivot arm (Fig. 7). Tighten

they do not contact the flat surface.
C. Insert a piece of bar stock 25" - 28" (70 cm) long
(Fig. 8), and approximately 1/8" (3 mm) thicker than
the desired height-of-cut, under the reel and up
against the bedknife cutting edge (Fig. 8). The reel
(not bedknife) must contact the bar stock along its
full length.
NOTE: Using a bar 1 /8" (3 mm) thicker than height-of-
cut
provides proper bedknife attitude (heeled “up” in
back) required for excellent low height-of-cut perform-
ance.
D. Loosen rear roller jam nuts and adjusting knobs
and push roller down against flat surface. At this
point the reel should contacting the bar stock and the
rear roll contacting the flat surface. Contact should
