DESCRIPTION
The RC466 Rough Cut Mower will cut through tall, dense growth and 1" woody stems. Free-swinging
blades on discs all but eliminate shock load to the four spindles. Chains at the front opening allow
unrestricted access for tall growth. Counter rotating disc blades move material freely to the rear discharge.
Mounted on the front lift, this mower cuts the growth before it is pressed down by the tractor, and offers
excellent visibility to your work.

SAFETY
SAFE OPERATION PRACTICES FOR
MOWERS
This cutting machine is capable of amputating
hands and feet and throwing objects. Failure to
observe the following safety instructions could
result in serious injury or death.
I GENERAL OPERATION
1. Read, understand, and follow all instructions in
the manual and on the machine before starting.
2. Only allow responsible adults, who are familiar
with the instructions, to operate the machine.
3. Clear the area of objects such as rocks, toys ,
wire, etc., which could be picked up and thrown
by the blade.
4. Be sure the area is clear of other people before
mowing. Stop the machine if anyone enters the
area.
5. Never carry passengers.
6. Do not mow in reverse unless absolutely
necessary. Always look down and behind
before and while backing.
7. Slow down before turning.
8. Never leave a running machine unattended.
Always turn off blades, set parking brake, stop
engine, and remove keys before dismounting.
9. Turn off blades when not mowing.
10. Stop engine before unclogging or cleaning
under deck.
11. Mow only in good light, keeping away from
holes and hidden hazards.
12. Do not operate the machine while under the
influence of alcohol or drugs.
13. Watch for traffic when operating near or
crossing roadways.
14. Use extra care when loading or unloading the
machine into a trailer or truck.
15. Always wear safety goggles or safety glasses
with side shields when operating mower.
II SLOPE OPERATION
Slopes are a major factor related to
loss-of-control and tip-over accidents, which can
result in severe injury or death. All slopes
require extra caution. If you feel uneasy on it, do
not mow it.
DO:
• Mow up and down slopes where possible.
• Remove obstacles such as rocks, tree limbs,
etc.
• Watch for holes, ruts, or bumps. Uneven terrain
could overturn the machine. Tall grass can hide
obstacles.
• Use slow speed (low range). Do not attempt to
shift while on the slope.
• Follow the manufacturers recommendations for
wheel weights or counterweights to improve
stability.
• Keep all movement on the slope slow and
gradual. Do not make sudden changes in
speed or direction.
• Avoid stopping or starting on a slope. If tires
lose traction, disengage the blades and proceed
slowly straight down the slope.

SAFETY
DO NOT:
• Do not turn on slopes unless necessary, and
then, turn slowly and gradually downhill, if
possible.
• Do not mow drop-offs, ditches, or
embankments. The mower could suddenly turn
over if a wheel is over the edge of a cliff or
ditch, or if an edge caves in.
• Do not mow on wet grass. Reduced traction
could cause sliding.
• Do not try to stabilize the machine by putting
your foot on the ground.
III CHILDREN
Tragic accidents can occur if the operator is not
alert to the presence of children. Children are
often attracted to the machine and the mowing
activity. Never assume that children will remain
where you last saw them.
1. Keep children out of the mowing area and under
the watchful eye of another responsible adult.
2. Be alert and turn machine off if children enter
the area.
3. Before and when backing, look behind and
down for small children.
4. Never carry children as passengers, even with
the blades turned off. They may suddenly fall
off and be seriously injured or interfere with safe
machine operation.
5. Never allow children to operate the machine.
6. Use extra care when approaching blind corners,
shrubs, trees, or other objects that may obscure
vision.
IV SERVICE
1. Use extra care in handling gasoline and other
fuels. They are flammable and the vapors are
explosive.
a. Use only an approved container.
b. Never remove gas cap or add fuel with
engine running. Allow engine to cool before
refueling. Do not smoke.
c. Never refuel or drain the machine indoors.
d. Never store the machine or fuel container
inside where there is an open flame, such
as in a water heater.
2. Never run the machine in a closed area.
3. Keep nuts and bolts, especially blade
attachment bolts, tight and keep equipment in
good condition.
4. Never tamper with safety devices. Check their
proper operation regularly.
5. Keep machine free of grass, leaves, and other
debris build-up. Clean up oil or fuel spillage.
Allow machine to cool before storing.
6. Stop and inspect the equipment if you strike an
object. Repair, if necessary, before restarting.
7. Never make adjustments or repairs with the
engine running.
8. Frequently check components and replace with
manufacturer’s recommended parts, when
necessary.
9. Mower blades are sharp and can cut. Wrap the
blade(s) or wear gloves, and use extra caution
when servicing them.
