General Operating Instructions
It is important that you familiarize yourself with the
Operator’s Manual, complete the Operator’s Checklist,
properly attach the cutter to your tractor, make leveling
adjustments, preset cutting height, and set wing folding
hydraulic control lever to the float position before
beginning a running operational safety check on your
Land Pride RC4615 or RCM4615 Series Rotary Cutter.
It’s now time to do a running operational safety check. It
is important that at any time during this safety check you
detect a malfunction in either the cutter or tractor that you
immediately shut the tractor off, remove the key, and
make necessary repairs and/or adjustments before
continuing on.
Before starting the tractor, make sure the gear selector is
in park or park brake is engaged, power take-off is
disengaged, and cutter is resting on the ground with both
wings down. Start the tractor and set engine throttle
speed at a low idle. Raise cutter with tractor’s rear
hydraulic lift control lever to transport position making
sure that the power take-off shaft does not bind and does
not contact the cutter frame. Lower cutter to the ground
and at a low engine speed engage power take-off. If
everything is running smoothly at a low idle, slowly raise
the cutter to transport height checking for bind or chatter
in the driveline. Lower cutter to the ground and increase
tractor’s engine rpm until it reaches the cutter’s full power
take-off operating speed which will be either 540 or 1000
rpm. If everything is still running smoothly, once more
raise the cutter to transport height to check for driveline
bind or chatter. Lower cutter to the ground, return engine
to a low idle, and disengage power take-off. Make a tight
turn to ensure that the rear tractor tires are not coming in
contact with the hitch or deck. Also, be sure tractor 3-
point arms are raised and will not contact main driveline.
You should now be ready to transport to your cutting site
at a safe ground speed. On roadways, transport in such
a manner that faster moving vehicles can easily see you
and pass you safely. Reduce your speed when traveling
over rough and hilly terrain. Avoid quick or sharp steering
corrections. Take extra care to ensure that the mower
doesn’t come into contact with obstacles such as trees,
buildings, or fences. Use optional light kit and appropriate
reflective devices to provide adequate warning to
pedestrians and other vehicle operators when traveling
on public roads and in the dark of night. Comply with all
local, state and federal laws.
It is important that you inspect the area where you will be
cutting and clear it of safety hazards and foreign objects
either before or after you arrive at the cutting site. Never
assume the area is clear. Cut only in areas which you are
familiar with and are free of debris and unseen objects.
Extremely tall grass should be cut twice to detect
potential hazards. In the event you do strike an object
stop the cutter and tractor immediately to inspect and
make necessary repairs to the cutter before resuming
operation. It really pays to inspect a new area and to
develop a safe plan before cutting.
You will need to maintain either 540 or 1000 rpm power
take-off speed and 2 to 5 mph ground speed to produce a
clean cut. Make a tractor gear and range selection that
will enable you to maintain these speed combinations.
Generally the quality of cut is better at lower ground
speeds. Dense ground cover will create the need to slow
down even more. In certain conditions tractor tires will roll
grass down resulting in an uneven cut when the grass
fails to rebound. Should this happen you may try
reversing the direction of cut and/or double cut to achieve
the desired finish. Avoid very low cutting heights
especially on extremely uneven terrain. Always cut
downward on slopes and avoid crossing the face of steep
slopes. Avoid sharp drops and cross diagonally through
dips to prevent hanging up the tractor and cutter. Slow
down in turns and avoid sharp turns if at all possible.
Remember to look back often.
Now that you’re prepared and well briefed you may begin
cutting. Begin cutting by doing the following:
•
Reduce tractor’s engine rpm.
•
Make sure the wheels supporting the wings are on the
ground and the hydraulic control lever for folding the
wings is set in float position.
•
Engage power take-off, raise engine rpm to the
appropriate power take-off speed, and begin mowing.
Try increasing or decreasing ground speed to determine
the effect on quality of cut. With a little practice you will be
pleased with what you and your Land Pride 15' Smooth
Top Cutter can do.
When you are done mowing, need to take a break, or just
need to make a few adjustments to the cutter, remember
to always do the following:
•
Reduce tractor’s engine rpm and disengage power
take-off.
•
Stop on level ground, place gear selector in park or set
park brake, turn off engine, remove switch key, and
stay on the tractor until cutter blades have come to a
complete stop.
