14 Operation
MAN0571 (Rev. 6/15/2007)
OPERATION
The operator is responsible for the safe operation of
the cutter. The operator must be properly trained.
Operators should be familiar with the cutter, the tractor,
and all safety practices before starting operation. Read
the safety rules and safety decals on pages 7 to 13.
This heavy-duty cutter is designed for grass and weed
mowing and shredding.
Recommended mowing speed for most conditions is
from 2 to 5 mph.
Full chain or rubber shielding must be installed
when operating in populated areas or other areas
where thrown objects could injure people or dam-
age property.
• If this machine is not equipped with full chain
or rubber shielding, operation must be stopped
when anyone comes within 300 feet (92 m).
• This shielding is designed to reduce the risk
of thrown objects. The mower deck and protec-
tive devices cannot prevent all objects from
escaping the blade enclosure in every mowing
condition.
It is possible for objects to ricochet
and escape, traveling as much as 300 feet (92 m).
Never allow riders on power unit or attachment.
Make sure spring-activated locking pin or collar
slides freely and is seated firmly in tractor PTO
spline groove.
Operate tractor PTO at 540 RPM (1000 RPM on Q
Series cutters). Do not exceed.
Do not allow bystanders in the area when oper-
ating, attaching, removing, assembling, or servic-
ing equipment.
Stop power unit and equipment immediately
upon striking an obstruction. Turn off engine,
remove key, inspect, and repair any damage before
resuming operation.
Always wear relatively tight and belted clothing
to avoid getting caught in moving parts. Wear
sturdy, rough-soled work shoes and protective
equipment for eyes, hair, hands, hearing, and head;
and respirator or filter mask where appropriate.
Safety tow chain must be hooked-up to both the
implement and tractor during operation or trans-
port. A loose, dragging chain could be struck by
the blades causing serious injury.
TRACTOR STABILITY
A minimum 20% of tractor and equipment
weight must be on the tractor front wheels when
attachments are in transport position. Without this
weight, tractor could tip over, causing personal
injury or death. The weight may be attained with
front wheel weights, ballast in tires or front tractor
weights. Weigh the tractor and equipment. Do not
estimate.

(PULL-TYPE)
NOTICE
■ For tractors with a 1-3/8" diameter PTO shaft,
the horizontal distance from end of tractor PTO
shaft to center of drawbar pin should be 14" for the
540 rpm cutter and 16" for the 1000 rpm cutter.
Tractors with a 1-3/4" 20-spline PTO shaft should
be set to 20". This will minimize joint knock and
damage to drive components.
1. Adjust tractor drawbar to obtain the desired
drawbar-to-hitch-point distance.
NOTE: On some tractors, a drawbar kit must be
used to obtain the required dimension. Check with
your tractor dealer for assistance.
2. Attach parking jack to cutter tongue. Raise tongue
to tractor drawbar height.
3. Secure cutter to tractor drawbar with a high-
strength drawbar pin 3/4” or larger. Keep pin in
place during operation.
4. Loop safety tow chain around tractor drawbar
support. Secure the hook to a chain link that allows
enough slack for proper hitch articulation.
