The designed and tested safety of this machine de-
pends 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 responsibili-
ty 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 BW15.51
and BW10.51; on BW15.51Q and BW10.51Q operate
PTO at 1000 RPM.
DANGER
■ Full chain shielding must be installed at all
times. Thrown objects could injure people or
damage property.
•
If the machine is not equipped with full chain
shielding, operation must be stopped.
•
This shielding is designed to reduce the risk
of thrown objects. The mower deck and pro-
tective 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 (92m).
WARNING
■ Never allow children or untrained persons to op-
erate equipment.
■ Do not allow bystanders in the area when op-
erating, attaching, removing, assembling, or
servicing equipment.
■ Make sure spring-activated locking pin or collar
slides freely and is seated firmly in tractor PTO
spline groove.
CAUTION
■ Stop power unit and equipment immediately
upon striking an obstruction. Turn off engine,
remove key, inspect, and repair any damage be-
fore resuming operation.
■ Always wear relatively tight and belted clothing
to avoid entanglement in moving parts. Wear
sturdy, rough-soled work shoes and protec-
tive equipment for eyes, hair, hands, hearing,
and head; and respirator or filter mask where
appropriate.

OPERATION
CONNECTING CUTTER TO TRACTOR
■ 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 540 RPM cutter and 16" for the 1000
RPM cutters. This will minimize joint knock and
damage to drive components.
Use of the CV Lift Assist System
The Batwing
port the driveline while connecting and disconnecting it
from the tractor. Follow the instructions below.
1. Remove klik pin.
2. Lift lever to vertical position which will lift driveline.
3. Connect coupler to tractor PTO shaft.
4. Lower lever and secure with klik pin.
If the driveline is held too high or low, the roller carriage
can be adjusted by removing the mounting bolts, mov-
ing it to the preferred position, and replacing the bolts.
If the tractor used to power the Batwing
shaft and drawbar closer than the current stan-
dards, the driveline could contact the lift assist
frame or roller during use and could cause damage
and failure to the driveline. When using a tractor
of this type, the CV lift assist system should be re-
moved from the tongue to avoid potential contact
and damage.
