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 BW180XHD
and BW126XHD; on BW180XHDQ and BW126XHDQ
operate PTO at 1,000 rpm.
 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 540 rpm cutter and 16" for the 1000 rpm cut-
ters. This will minimize joint knock and damage to
drive components.
NOTE: Remove CV drive shipping bracket before
operation and discard. This bracket is only sup-
plied on factory assembled units with a CV drive
installed.
Figure 1. Cutter to Tractor Connection
1. Attach cutter using a 1-1/2" clevis pin and clip.
2. Attach safety tow chain (32) to drawbar support.
Leave enough slack for turning (Figure 1).
3. Connect cutter driveline to tractor PTO shaft,
making sure the spring-activated lock pin slides
freely and is seated in tractor PTO splined groove.
4. Attach driveline shield tether chain to tractor
drawbar to prevent rotation.
NOTE: CV driveline does not require a tether
chain.
5. Remove parking jack (29) from the tongue and
attach it to the storage post on the front of the left
wing.
NOTE: Equal Angle Drive Only: With cutting height
established, adjust the 3-joint H-frame bearing
height so that the front driveline is parallel to the
ground.
