14 Operation
MAN0764 (11/5/2008)
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
information on page 7 through page 13.
Recommended tractor ground speed for most condi-
tions is from 1 to 6 mph.
Always operate tractor PTO at 540 rpm on models
BW2400X and BW1620X (1000 rpm on models
BW2400XQ, BW1620XQ and BW1620XQREV).
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 children or untrained persons to
operate equipment.
Do not allow bystanders in the area when oper-
ating, attaching, removing, assembling, or servic-
ing equipment.
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.
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.
CONNECTING CUTTER TO TRACTOR
NOTICE
For tractors with a 1-3/8" diameter PTO shaft,
the horizontal distance from the end of the tractor
PTO shaft to the center of drawbar pin should be
14" for the 540 rpm cutter and 16" for the 1000 rpm
cutter. Tractors with 1-3/4 20-spline PTO shaft
should be set to 20". This will minimize joint knock
and damage to drive components.
Figure 1. Cutter to Tractor Connection
1. Check tongue clevis to make sure it is adjusted to
match your tractor PTO speed. See Figure 26,
page 36.
2. Position tongue clevis (A) up or down based on
tractor drawbar height.
