TABLE OF CONTENTS
We welcome you as an owner of a Gearmore mower. Please read the
following instructions and refer to them when required:
1. Inspect for damage and loose or missing parts. Make sure all fittings and
drive components are secure.
2. Lubrication (See Lubrication Section).
3. Remove all large, foreign objects from area being mowed.
1. Connect mower to the tractor 3-point hitch lower link arms. (Make sure
tractor and mower are on a level surface.)
2. Connect top link of tractor to mower and adjust turnbuckle so the mower
is level with the ground.
3. Install driveshaft after making sure it is the correct length. (See separate
warning sheet on the correct method of achieving the proper driveshaft
length.)
4. Set height of tailwheel based on what height you want to cut. Example:
The blades are set 1” above the skids. Thus, if you want a 2” cut, you
would set tailwheel so skids are 1” above ground.
NOTE: The mower is designed to float on the tailwheel and mower 3-
point hitch, so the mower should not be dragged on the ground.
5. Set height stops on the tractor 3-point lift so mower will not be raised
higher than necessary. Failure to do this could cause damage by putting
excessive angle on the driveshaft.
6. Engage the tractor PTO when tractor engine is at idle speed. Engaging the
PTO with engine at full speed will reduce the life of the driveshaft. For
most cutting operations, a ground speed of 3 to 5 MPH and PTO at full 540
RPM is recommended.

Continued....
Front tractor weights or front tire ballast should be used to enhance front end
stability on small tractors.
NEVER operate mower in raised position.
Check to make sure PTO is properly connected
and that the driveline is correct to prevent
bottoming out or pulling apart during the full
lift range of the hitch.
This implement is designed for a one-man operation. It is the responsibility
of the tractor operator to see that no one is in the proximity of the implement
when it is started. DO NOT operate the implement when another person is
within 25’ of the implement.
