Extending or lengthening the top link will raise your
cutting height, while shortening the top link will lower the
cutting height. If you are cutting in an area you are not
familiar with or believe there might be rocks or debris
present, you must raise the cutting height accordingly.
This will reduce the potential of personal injury and/or
damage to the machine. Shut the mower down
immediately if someone approaches in a vehicle or on
foot.
If you do hit an object when you are mowing, immediately
disengage the PTO, idle the engine, stop the tractor, wait
for all moving parts to come to a complete stop, shut off
the tractor, set the brake, remove the keys, and inspect
for damage. If damage is present, make the necessary
repairs. If no damage is present, but you have tripped the
Break Away Safety Latch, slowly reverse the tractor until
the latch resets and proceed with mowing operations.
Prior to actually beginning cutting operations, you will
want to get the mower up to full 540 rpm PTO speed by
engaging the PTO with the tractor engine at idle and
gradually increasing engine rpm to PTO speed. Once
you reach the full 540 rpm, allow the mower to run for a
few minutes at level position so the oil in the cutter bar
can lubricate all internal moving parts. You will also want
to take this opportunity to make a quick Operational
Running Check. Listen and visually inspect for any
component or part that may be loose or out of
adjustment. Don’t be alarmed by the noise level of the
free running Disc Mower. It will actually become quieter
when you begin mowing and have some run in time on it.
If your Operational Running Check was ok, begin
mowing operations by opening up lands on your field.
Make enough lands so you can easily make turns to
properly line up for each pass down the field. If your
tractor and Disc Mower are set up right, you should be
able to straddle the previous swath as you make each
subsequent pass starting in the center of the field. If you
do experience cutting problems, refer to the “Trouble
Shooting” section of the Operator’s Manual for corrective
action.
When you are done mowing for the day and need to
transport the mower to your storage site, simply pull on
the field run latch rope and retract the hydraulic cylinder
until the transport latch engages.
When you are done mowing for the season, clean and
lubricate your mower, replace warn or missing parts,
release tension on the belts, install the stroke control to
the tarp frame cushion spring rod and store the unit with
the cutter bar in the horizontal working position. You will
get longer service life out of your mower by storing it
inside and repainting scratched or rusted components.
With a little practice and experience you should become
very good at operating your Land Pride Disc Mower.
