Operation 13
15914 (Rev. 3/30/2007)
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
mounted or towed unit will be identified in the text.
Information applicable to either unit will not be segre-
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 must be installed when
operating in populated areas or other areas where
thrown objects could injure people or damage
property.
• If this machine is not equipped with full chain
shielding, operation must be stopped when any-
one 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 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, set
parking brake, 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, front tractor wheels could raise up result-
ing in loss of steering. The weight may be attained
with front wheel weights, ballast in tires, front trac-
tor weights or front loader. Weigh the tractor and
equipment. Do not estimate.
ATTACHING MOUNTED CUTTER TO
