OPERATION
The designed and tested safety of this machine
depends on it being operated within the limitations as
explained in this manual. Be familiar with and follow all
safety rules in the manual, on the cutter and on the
tractor.
The safe operation of this cutter is the responsibility of
the operator, who must be properly trained. The opera-
tor should be familiar with the equipment and all safety
practices before starting operation. Read the Safety
Rules on page 7 through page 12.
Information specific to attaching or operating the

gated.
This cutter is designed for shredding heavy brush, such
as prunings in orchards, groves and vineyards. Other
applications include topping onion sets and potatoes
before harvesting. It may also be used to shred green
manure crops, straw and stubble, asparagus residue
etc. prior to plowing. Recommended tractor ground
speed for most mowing conditions is from 1 to 5 mph.
Always operate tractor PTO at 540 rpm.
Full chain shielding, designed to reduce the
possibility of thrown objects, 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 shielding, operation must be stopped
when anyone comes within 300 feet.
Never allow children or untrained persons to
operate equipment.
Keep bystanders away from equipment.
Before performing any service or maintenance,
lower equipment to ground or block securely, turn
off engine, remove key, and disconnect driveline
from tractor PTO.
On pull-type units, a pin is installed to prevent
the height adjustment crank from detaching. Do
not operate or service unit unless pin is installed.
Keep all persons away from operator control
area while performing adjustments, service, or
maintenance.
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.
Make sure spring-activated locking pin or collar
slides freely and is seated firmly in tractor PTO
spline groove.
Stop power unit and equipment immediately
upon striking an obstruction. Turn off engine,
remove key, inspect, and repair any damage before
resuming operation.
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 a
loader, front wheel weights, ballast in tires or front
tractor weights. Weigh the tractor and equipment.
Do not estimate.
