SET-UP INSTRUCTIONS
Page 5
Your Gearmore Finishing Mower has been carefully assembled at the factory. By following a
few simple instructions, your Finishing Mower will be ready for dependable service.
This Finishing Mower is designed to fit most tractors equipped with a standard three (3) point
system. The lift pins on the mower are classified as Category I. The Finishing Mower is shipped
from the factory with a safety shielded PTO shaft. This mower is designed to mow grass only.
Before placing your Gearmore Finishing Mower in service, please follow these instructions very
carefully. Your mower was shipped from the factory with no oil in the gearbox nor grease
in blade spindles and wheel axles. Fill the gearbox approximately one-third full with at least
90 weight oil. Grease the PTO shaft in two places before putting in service and after every
eight hours use. Grease the roller after every eight hours of use. There are three (3) blade spin-
dle housings. The tops of each blade spindle housing are visible through three (3) access holes
in the top safety shield. Grease these blade spindle housings through the top of the shaft
before placing in service and after eight hours use. Adjust belts as necessary, keeping them tight
but not over-tight. When properly adjusted, belt should have approximately 3/4inch deflection
with 10 lb. pull.
TO ADJUST BELT
1. Remove top cover.
2. Release adjustment spring.
3. Loosen nut on adjustment pulley to allow for movement.
4. Loosen nut on right side of "L" bracket.
5. Turn nut on left side of "L" bracket in counterclockwise direction until belt is tight.
6. Re-tighten nut on right side of "L" bracket and nut on adjustment pulley.
7. Re-hook adjustment spring.
8. See Figure D.

BELT REPLACEMENT
TO REPLACE BELT:
STEP 1 Remove PTO shaft.
STEP 2 Remove top cover.
STEP 3 Loosen nut on adjustment pulley to allow for movement.
(See Figure D)
STEP 4 Loosen nut on right side of “L” bracket. (See Figure D)
STEP 5 Loosen belt by moving adjustment pulley in opposite direction you
would to tighten belt.
STEP 6 Remove belt from all pulleys and idlers, leaving it on the main pulley.
(See Figure E)
STEP 7 Loosen nuts (4) retaining the gearbox to the gearbox plate.
Note: the top of the nuts should be flush with the end of the bolts.
STEP 8 Remove bolts (4) holding the gearbox plate to the finishing mower deck.
STEP 9 Remove the gearbox and gearbox plate assembly from the finishing
mower. Note: the belt should be removed with the assembly.
STEP 10 Turn gearbox and plate assembly over and allow to rest on the gear
box. This will allow a space to develop between the main pulley and
the gearbox plate flange. The belt can be removed through this space.
STEP 11 Install new belt.
STEP 12 Reassemble by reversing steps 1 through 10.
After mounting the Finishing Mower to the tractor’s three point lifting system,
set the mower to the desired cutting height. Adjust height by arranging the different
spacers on the four wheels, see page 7, reference #1. This will result in relieving
the weight of the mower from the tractor’s lifting system. There are three height
positions for the chain adjustment. Select the height that allows the mower to float
freely over any terrain without any weight on the three (3) point lift system, see
reference 25, page 8. The Finishing Mower is not designed to cut foreign objects
such as steel rods, old tires or tubes, or tree limbs, etc. It is designed to cut grass
only.
