HEIGHT OF CUT ADJUSTMENT
To set the height of cut, lift the
Socket/Vinyl
Cap of the Dial-A-Height
TM
(1, Figure 17) up
then turn clockwise (viewed from above) to
lower the roller (4, Figure 17) (raise the height
of cut), or counter-clockwise to raise the roller
(lower the height of cut).
NOTE: Each quarter turn (90°) of the
Socket/Vinyl Cap will raise or lower the height
of cut by approx. 1/32”. A full turn (360°) will
raise or lower the height of cut by approx.
1/8”.
IMPORTANT: Rollers must be adjusted to the
same height so that there will be uniform
cutting the entire width of the mower.
The Height Adjustment Scale Decal (2,
Figure 17) will provide approximate height of
cut corresponding to the Socket/Vinyl Cap
rotation.
1. Sight along the bottom edge of the
Adjuster Tube (3, Figure 17) to achieve
the desired cut height.
2. When making large adjustments to the
height of cut (over 1/2”), it is easier to
make small incremental adjustments to
each side until the desired change is
achieved, making sure the Socket/Vinyl
Cap is locked in position.
3. If very accurate cutting heights are
required, place a board or other gage
plate (of desired thickness) on a smooth
flat surface under each bedknife back
bar (1, Figure 22) and adjust the roller
height accordingly.
REEL TO BEDKNIFE
ADJUSTMENT
The reel is adjusted to a fixed position
bedknife. This makes a more rugged and
durable frame and retains proper adjustment
longer. The reel adjuster bolt (5, Figure 17)
regulates the reel distance from the bedknife.
1. To reduce the distance, turn the locking
hex nut on each side of the reel down
with special reel adjustment wrench (6,
Figure 17) and then tighten top nut.
2. Proceed slowly and do not over adjust—
about 1/6 (one flat) of a turn on each
side to begin with. Do not get the reel so
tight that it is hard to turn by hand. A too
tight reel will wear much faster. The reel
should “wipe” or lightly touch the
bedknife.
3. Check to see that blades are cutting the
paper all the way across, using paper
strips held between reel and bedknife.
4. Make sure adjustment nuts are tight
before
mowing.
REEL END PLAY ADJUSTMENT
As the reel is used, normal wear of the reel
bearings will cause end play. This condition
could cause uneven wear to moving parts
and uneven cutting of turf.

DANGER: Use heavy gloves and
be careful. Bedknife and reel blades
are very sharp.
