Cutter Blade Maintenance

DANGER

Always disconnect main driveline from tractor PTO before
servicing underside of cutter. PTO can be engaged if tractor is
started causing cutter damage, bodily injury or death.

DANGER

Always secure cutter deck in the up position with solid
supports before servicing underside of cutter. Never work
under equipment supported by hydraulics. Hydraulics can
drop equipment if controls are actuated or if hydraulic lines
burst. Either situation can drop the cutter instantly even when
power to the hydraulics is shut off.

WARNING

Do not operate cutter with blades that are bent, out-of-
balance, excessively worn, excessively nicked, or with blade
bolts that are excessively worn. Such blades can break loose
from the cutter at high speeds causing serious injury or death.

WARNING

Wait for blades to come to a complete stop before accessing
blade bolts through blade bolt access hole.

CAUTION

ALWAYS wear gloves and eye protection while inspecting,
removing, sharpening, and replacing cutter 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
blade! Small nicks can be ground out when sharpening.
Refer to Figure 5-2 on page 39 when ordering Land Pride
replacement blade components.

Remove cutting blades and sharpen or replace as
follows:

Place tractor gear selector in park and/or set brakes,
shut engine off and remove ignition key.

Disconnect main driveline from tractor PTO and
secure cutter deck in the up position with solid
supports before servicing underside of cutter.

IMPORTANT: Replace cutting blades with genuine
Land Pride blades only. Blades must be replaced in
mating pairs. Not replacing both blades will result in
an out-of-balance condition that will contribute to
premature bearing breakdown on the spindle hub
and create structural cracks in the cutter housing.

Section 5: Maintenance & Lubrication

General Maintenance Information

Proper servicing and adjustments are key to the long life
of any implement. With careful inspection and routine
maintenance, you can avoid costly downtime and repair.

The parts on your Rotary Cutter have been specially
designed and should only be replaced with genuine Land
Pride parts. Do not alter the cutter in a way which will
adversely affect its performance.

Check all bolts and pins after using the cutter for several
hours and on a regular basis thereafter to ensure they are
tight and secured. Replace worn, damaged, or illegible
safety labels by obtaining new labels from your Land
Pride dealer.

DANGER

Perform maintenance only on a cutter that is not running.
Disengage PTO, place tractor in park or set park brake, shut
tractor engine off, remove switch key, and wait for blades to
come to a complete stop before dismounting tractor to perform
maintenance.

WARNING

Frequently check all hardware to make certain it is tight and
not broken or missing. Such hardware can cause the cutter to
not perform properly and may lead to breakage that can cause
bodily injury or death.

WARNING

Replace worn, damaged, or missing parts with genuine Land
Pride parts only. Replacing parts with other brands can cause
the equipment to not perform properly and may lead to
breakage that can cause bodily injury or death.

WARNING

Do not operate cutter with loose pins, bolts, or nuts. Loose
hardware can result in a serious breakdown causing bodily
injury or death.

CAUTION

Do not alter the Rotary Cutter in a way which will adversely
affect its performance or safety. Doing so can damage the
cutter, cause personal injury and void the warranty.

Tractor Maintenance

One of the most important things you can do to prevent
hydraulic system problems is to ensure your tractor's
hydraulic reservoir remains free of dirt and other
contaminations.

Use a clean cloth to wipe hose ends before attaching
them to your tractor. Replace your tractor’s hydraulic filter
element at the prescribed intervals. These simple
maintenances will go a long way to prevent occurrence of
control valve and hydraulic cylinder problems.
