16 Operation
5WPMAN0183 (Rev. 4/25/2008)
STARTING AND STOPPING MOWER
Do not operate PTO during transport.
Never direct discharge toward people, animals,
or property.
Keep hands, feet, hair, and clothing away from
equipment while engine is running. Stay clear of all
moving parts.
Stop power unit and implement immediately
upon striking an obstruction. Dismount power unit,
using proper procedure. Inspect and repair any
damage before resuming operation.
Always sit in power unit seat when operating
controls or starting engine. Securely fasten seat
belt, place transmission in neutral, engage brake,
and ensure all other controls are disengaged
before starting power unit engine.
Power for operating the mower is supplied from the
tractor PTO. Refer to your tractor manual for instruc-
tions on engaging and disengaging the PTO.
Operate PTO at 540 rpm. Know how to stop tractor and
mower quickly in case of an emergency.
If the mower becomes plugged causing the belt to slip
for over two seconds, follow these steps:
1. Raise mower just enough to clear accumulated
material.
2. Continue running at least two minutes, allowing
pulleys to cool.
NOTICE
Stopping the mower with belt in contact with a
very hot pulley will bake and ruin belt.
To reduce the risk of thrown objects, do not raise the
mower higher than necessary.
OPERATING
Do not operate mowers on terrain that raises
mowers beyond 25 degrees. Exceeding this design
limit will result in U-joint “knocking noise” and
potential driveline failure and could cause driveline
to pull apart.
When engaging the PTO, engine rpm should always be
low. Once engaged and ready for mowing, increase
PTO speed to 540 rpm and maintain speed throughout
the cutting operation.
Mower vibration tends to loosen bolts. All hardware
should be checked regularly to maintain proper torque.
Each time the mower is used, check all hardware to be
sure it is secure.
The condition of the terrain will determine cutting
results. For best results, mower blades should be kept
sharp at all times and the platform as level as possible.
When mower blades show excessive wear, they should
be replaced.
Operating Technique
Stop power unit and implement immediately
upon striking an obstruction. Dismount power unit,
using proper procedure. Inspect and repair any
damage before resuming operation.
Proper ground speed will depend upon the terrain, the
height, type, and density of material to be cut.
Normally, ground speed will range from two to five
mph. Tall dense material should be cut at a low speed;
thin medium-height material can be cut at a faster
ground speed.
Always operate tractor PTO at 540 rpm to maintain
proper blade speed and produce a clean cut.
Under certain conditions, tractor tires may roll some
grass down and prevent it from being cut at the same
height as the surrounding area. When this occurs,
reduce your ground speed, but maintain PTO at 540
rpm. The lower ground speed will permit grass to par-
tially rebound.
In general, lower cutting heights give a more even cut
with less tendency to leave tire tracks. However, it is
better to cut grass frequently rather than too short.
Short grass deteriorates rapidly in hot weather and
invites weed growth during growing seasons. Follow
local recommendations for the suitable cutting height in
your area.
Operating Tips
Inspect and clear area of stones, branches, or
other hard objects that might be thrown, causing
injury or damage.
Extremely tall material should be cut twice. Set mower
at a higher cutting height for the first pass. Then cut at
desired height 90 degrees to the first pass.
Remember, sharp blades produce cleaner cuts and
require less power.
