OPERATION
The operator is responsible for the safe operation of
the mower. The operator must be properly trained.
Operators should be familiar with the mower, the trac-
tor, and all safety practices before starting operation.
Read the safety rules and safety decals on page 5
through page 9.
This mower is designed for lawn and grass mowing. It
is not designed for rough conditions or heavy weed
mowing. It is equipped with suction type blades for best
results in lawn mowing.
Recommended mowing speed for most conditions is
from 2 to 5 mph.
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.
Make sure spring-activated locking pin or collar
slides freely and is seated firmly in tractor PTO
spline groove.
Operate tractor PTO at 540 RPM. Do not exceed.
Before working underneath, carefully read Oper-
ator’s Manual instructions, disconnect driveline,
raise mower, securely block up all corners with
jackstands, and check stability. Secure blocking
prevents equipment from dropping due to hydrau-
lic leak down, hydraulic system failures, or
mechanical component failures.
Keep all persons away from operator control
area while performing adjustments, service, or
maintenance.
Stop power unit and implement immediately
upon striking an obstruction. Dismount power unit,
using proper procedure. Inspect and repair any
damage before resuming operation.
Always wear relatively tight and belted clothing
to avoid entanglement 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.
TRACTOR STABILITY
A minimum 25% 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. Weigh the tractor and equipment. Do not
estimate.

ATTACHING MOWER TO TRACTOR
Make sure spring-activated locking pin or collar
slides freely and is seated firmly in tractor PTO
spline groove.
The standard 1-3/8" 6B-spline driveline with a QD yoke
is used to connect the mower to the tractor.
1. Attach the mower hitch pins to the lower tractor lift
arms and secure.
2. Attach tractor top link (1), Figure 2, to mower top
link bracket attachment point (A). Connect the
driveline to the tractor PTO shaft.
3. Attach tether chain to tractor drawbar (Figure 3).
