Reel Cut Height Adjustment
The front and rear rollers of each mower reel determine the cutting
height. Adjust the rollers up or down to achieve the desired cutting
height and to ensure that each unit is cutting level. This procedure
must be carried out at the front and rear and at both sides of each
mower reel to ensure an even cut height across the mower unit.
This procedure requires use of Cutting Height Adjustment Bar (p/n
02374800).
To adjust the cutting height (Figure 18):
1. Place mowing reels in the transport position.
2. Adjust rollers (1) to minimum height by releasing locknuts (2)
and moving the rollers upwards.
3. Set the desired cutting height on the adjusting bar front
adjusting screw (3) as indicated by dimension A.
4. Position the adjusting bar (4) with the head of the front
adjusting screw resting on the top lip of the be knife (5).
Tighten the rear adjusting screw (6) until it contacts the
bedknife holder with the adjusting bar parallel to the bedknife.
5. Adjust the roller cut height adjusters until the rollers just
contact the adjusting bar. Do not overtighten. The adjusting bar
should be loose enough to be slid forward without loosening
the adjusting screw.
6. Tighten the locknuts and remove the adjusting bar.
Reel-to-Bedknife Adjustment
1. Loosen the locking screws (both sides, Figure 19 & Figure 20)
until the washer can be moved by hand.
2. Turn one adjusting screw slowly while rotating the reel by
hand. When reel-to-bedknife contact is made, back off the
screw slightly and adjust the other side.
NOTE: 1/6 of a turn equals .004" change in adjustment of the
reel-to-bedknife. When light contact is made, check the cut with
double thickness of a sheet of newspaper. If one side cuts and the
other does not, back off the tight side and tighten the loose side.
Retighten locking screws.
IMPORTANT: The ideal setting maintains an extremely light
reel-to-bedknife contact with a clearance of.000 – .004"
(.000 – .102 mm).
• If the reelblades andbedknife aretoo far apart grasswill not
be cut because the grass will pass between the gap
between the reel and bedknife.
• If the blades contact too heavily the increased friction will
cause excessive wear and increase the power required to
drive the mower unit.

MAINTAINING BLADE SHARPNESS
Use Gravely Backlapper, part no. 79524700 or equivalent.
To provide consistent performance, the cutter blades need to be
backlapped on a regular basis, ideally after every 40 – 60 hours of
operation. 80-grit Lapping Compound is recommended (see
Accessories on page 16).
To backlap the reels:
1. Adjust the reel-to-bedknife clearance.
2. Adjust the bedknife-adjusting bolts to cause a slight friction
between the reel and the bed knife.
3. Saturate a special long-handled brush with lapping compound
and apply it to the length of the reel.
4. Continue lapping until the reel runs without the intermittent
grinding sounds caused by high spots.
5. Thoroughly clean all lapping compound from the cutter unit.
6. Adjust the bedknife adjusting bolts so that the reel blades just
contact the bedknife. Each blade should cleanly cut a thin
piece of paper at all points across the bed knife.
7. Repeat for remaining reels.
REEL CONTROL SWITCH ADJUSTMENT
The reel-control switch can be adjusted to change the height where
reel rotation starts and stops when raising and lowering the mower
reels (figure 21).
To lower the height where the reels stop rotation:
1. Loosen two switch adjustment screws.
2. Move the switch further away from the swing arm.
3. Tighten the switch adjustment screws.
To raise the height where the reels stop rotation:
1. Loosen two switch adjustment screws.
2. Move the switch in toward the swing arm.
3. Tighten the switch adjustment screws.
CAUTION: Sharp edges can cut or amputate fingers
or a hand. Use sturdy gloves or padding to protect
hands when working with reels.
DANGER: Stay away from the reel while backlapping.
Contact with the reel or other moving parts can result
in personal injury.
DANGER: NEVER use a short-handled paint brush
for backlapping. Use a long-handled brush designed
for this operation.

SHORT TERM
IMPORTANT: NEVER spray unit with high-pressure water or store
unit outdoors.
Inspect unit for visible signs of wear, breakage or damage.
Keep all nuts, bolts and screws properly tightened and know unit is
in safe working condition.
Store unit in a cool, dry protected area.
LONG TERM
Lower mower unit to surface.
Clean unit thoroughly with mild soap and low-pressure water and
lubricate (see Maintenance). Touch up all scratched painted
surfaces.
Remove weight from tractor wheels by putting blocks under frame
or axle.
Clean and charge the battery. Charge battery every three to four
weeks when storing unit.
Fuel System
Gasoline left in the fuel system for extended periods without a
stabilizer will deteriorate, resulting in gum deposits in the system.
These deposits can damage the carburetor and the fuel hoses,
filter and tank. Prevent deposits from forming in the fuel system
during storage by adding a quality fuel stabilizer to the fuel. Follow
the recommended mix ratio found on the fuel stabilizer container.
To treat the fuel system for storage:
• Add fuel stabilizer according to manufacturers’s instructions.
• Run engine for at least 10 minutes after adding stabilizer to
allow it to reach the carburetor.
NEVER store the engine with fuel in the fuel tank inside of a
building with potential sources of ignition.
STORAGE
WARNING: AVOID INJURY. Read and understand
the entire Safety section before attempting any
maintenance.
