Cutter Blade Maintenance
DANGER
!
To avoid serious injury or death:
•
Always disconnect driveline from the tractor before
servicing the drivetrain and components powered by the
drivetrain. A person can become entangled in the drivetrain
if the tractor is started and the power take-off is engaged.
•
Always secure equipment with solid, non-concrete supports
before working under it. Never go under equipment
supported by concrete blocks or hydraulics. Concrete can
break, hydraulic lines can burst, and/or hydraulic controls
can be actuated even when power to hydraulics is off.
WARNING
!
To avoid serious injury or death:
•
Do not operate cutter with blades that are out-of-balance,
bent, excessively worn, excessively nicked, or with blade
bolts that are excessively worn. Such blades can break loose

Wait for blades to come to a complete stop before accessing
blade bolts through blade bolt access hole.
•
Wear eye protection and gloves while inspecting, removing,
sharpening, and replacing a blade.
•
Do not attempt to straighten a bent blade or weld on a
blade. Do not attempt to modify a blade such as hard
surfacing, heat treating, cold treating, or by any other
method. Always replace blades with new Land Pride blades
Always inspect cutting blades before each use. Make
certain they are properly installed and in good working
condition. Replace any blade that is damaged, worn,
bent, or excessively nicked. Never try to straighten a bent
