Front Roller (Optional)
The caster wheels and side skids effectively reduce
scalping in most cases. However, you may encounter
areas where the caster wheels and/or side skids drop
into depressions and allow center of mower to contact
ground and scalp. An optional front roller may be
installed to minimize scalping.
Pre-Operation Check List
(OWNER RESPONSIBILITY)
Review and follow safety rules on pages 4
through 7.
Check that mower is properly and securely
attached to tractor.
Make sure driveline spring-activated locking pin
slides freely and is seated firmly in tractor PTO
spline groove.
Operate tractor PTO at 540 rpm.
Lubricate all grease fitting locations. Make sure
PTO shaft slip joint is lubricated.
Check to be sure gearbox is half-full of SAE 90W
gear lube.
Check that all hardware is properly installed and
secured.
Check to ensure blades are sharp and secure
and cutting edge is positioned to lead in a
clockwise rotation.
Check that all shields and guards are properly
installed and in good condition.
Check cutting height and attitude adjustment.
Place tractor PTO and transmission in neutral
before starting engine.
Inspect area to be cut and remove stones,
branches or other hard objects that might be
thrown, causing injury or damage.
IMPORTANT
J
Mower vibration tends to loosen bolts
during operation. All hardware should be
checked regularly to maintain proper
torque. It is a good practice to check
mower before each operation to ensure all
hardware is secure.
Operating Technique
Power for operating mower is supplied by tractor
PTO. Operate PTO at 540 rpm. Know how to stop
tractor and mower quickly in case of an emergency.
Should mower become plugged, causing belt to slip
for over two seconds, maneuver equipment into a
previously cut area and allow mower to clear
accumulated material. Continue running at least two
minutes, allowing pulleys to cool. Stopping the mower
in contact with a very hot pulley will bake and ruin belt.
CAUTION
J
Stop tractor and implement immedi-
ately upon striking an obstruction. Turn
off engine, remove key, 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. This is
necessary 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 at
least partially 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.
