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
!
To avoid serious injury or death:
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:
•
Perform scheduled maintenance. Check for loose
hardware, missing parts, broken parts, structural cracks,
and excessive wear. Make repairs before putting the
implement back into service.
•
Always shut tractor down using “Tractor Shutdown
Procedure” provided in this manual before servicing,
adjusting, cleaning, or maintaining this implement.
•
Do not alter implement or replace parts on the implement
with other brands. Other brands may not fit properly or
meet OEM (Original Equipment Manufacturer)
specifications. They can weaken the integrity and impair the
safety, function, performance, and life of the implement.
Replace parts only with genuine OEM parts.
•
Buildup of debris around moving components and
gearboxes is a fire hazard. Keep rotating parts and
gearboxes free from debris to avoid serious injury and
property damage.
•
Improper oil level can cause bearing failure and be a fire
hazard. Maintain proper gearbox oil level to avoid serious
injury and property damage.
Hydraulic System
One of the most important things you can do to prevent
hydraulic system problems is ensure that your tractor's
reservoir remains free of dirt and contamination.
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.
Tires
WARNING
!
To avoid serious injury or death:
•
Tire changing can be dangerous and should be performed
by trained personnel using correct tools and equipment.
When removing and installing wheels, use wheel handling
equipment adequate for the weight involved.
•
Always release all air pressure in air-filled airplane tires
before removing hardware bolting the split rims together.
Not doing so can cause the split rims to blow apart instantly
and could result in serious injury or death.
•
Tire changing can be dangerous and should be performed
by trained personnel using correct tools and equipment.
When removing and installing wheels, use wheel handling
equipment adequate for the weight involved.
•
Do not weld on or heat a rim. Air pressure inside the tire
can increase enough to cause an explosion. High heat can
weaken and/or warp the rim, damage the tire, and destroy
foam filling inside a tire.
1. Check tires for low air pressure, missing nuts,
missing lug bolts, wear, separated rubber, and bent,
broken, or cracked wheel rims.
2. Inflate air filled tires to the proper pressure. Refer to
“Tire Inflation Chart”
on page 64.
Refer to Figure 5-1:
3. Replace wheel rims and tires as needed with
genuine Land Pride parts. Do not loosen split rim
hardware (#1) until all air pressure in the tire has
been removed.
