General Maintenance
Refer to tractor’s service manual for proper tractor maintenance.
NEVER service the mower with the power on, except where otherwise stated.
Before working on a mower always check to see that:

The tractor’s transmission is in the parking gear and the parking brake is set to keep the
tractor from moving while unattended.

The tractor PTO has been disengaged.

The engine is off and all moving parts (both tractor and mower) have completely stopped.
The rotating parts of the tractor and mower continue to rotate after the PTO has been
disengaged. The operator should remain seated until all movement has ceased.
Never engage in repair or service work under the mower deck or any other part of the mower
that is raised off of the ground until the mower is safely and securely supported in the raised
position.
Use extreme caution when working on a mower. Many of the parts are heavy and sharp and
can cause serious injury if they are dropped or fall on the operator or bystander.
The blades are very sharp and can pivot. Use extreme caution when performing maintenance
on them. Failure to do so could result in serious injury or possibly even death.
Use marfac double ought grease or 0 weight cotton picker spindle grease to lubricate all Bush-
Whacker gearboxes. Replacement gearbox grease is available from your Bush-Whacker
dealership.
Always use genuine Bush-Whacker replacement parts, available through the network of
authorized dealers. The use of non-OEM parts will void the warranty of this machine.
Non-OEM parts may not meet Hall Manufacturing Inc. specifications and could lead to
serious injury or death.
At Least Twice Daily
Rotor Bar Assembly, Blades, Blade Bolts, and Nuts
 Check blades for any signs of cracking or damaged cutting surfaces. If a blade is cracked,
replace the set at once. DO NOT operate the mower at any time with a cracked or severely
damaged blade! If a blade breaks, it could cause severe injury or possibly death.

Check if blade cutting surfaces are dull. If they are, re-sharpen or replace blades.

Check if blade bolts and nuts are loose, cracked or damaged. DO NOT operate the mower
with any of those characteristics. Any of these conditions could allow the blade to come
loose and could cause injury or possibly death. Always keep the blade bolts and nuts
tightened to 350 ft. lbs. of torque.

DO NOT operate the mower with just one blade.
