General Maintenance
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.
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. Tighten all loose hardware as
indicated in the
“Torque Values Chart”
Replace worn, damaged, or illegible safety labels by
obtaining new labels from your Land Pride dealer.
Periodically, disengage power take-off, stop tractor, place
gear selector in park or set park brake, turn off tractor,
remove switch key and wait for blades to stop rotating
before dismounting tractor. Dismount tractor and check
for objects wrapped around blade spindles. Block deck
up before removing objects.
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
WARNING
!
To avoid serious injury or death:
•
Always shut tractor down using “Tractor Shutdown
Procedure” provided in this manual before dismounting
•
Perform scheduled maintenance. Check for loose
hardware, missing parts, broken parts, structural cracks,
and excessive wear. Make repairs before putting implement
back into service. Serious breakdowns can result in injury
•
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
•
Improper oil level can cause bearing failure and be a fire
hazard. Maintain proper gearbox oil level to avoid serious
Hydraulic System
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 clean before
attaching them to your tractor. Replace tractor 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.
Check for signs of damaged or worn hydraulic hoses,
fittings and cylinders before each use of the cutter.
Replace damaged components as needed.
WARNING
!
To avoid serious injury or death: Hydraulic fluid under high
pressure can penetrate the skin and/or eyes causing a serious
injury. Wear protective gloves and safety glasses or goggles
when working with hydraulic systems. Use a piece of
cardboard or wood rather than hands when searching for
leaks. A doctor familiar with this type of injury must treat the
injury within a few hours or gangrene may result. DO NOT
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.
•
When inflating tires, use a clip-on chuck and extension hose
long enough to allow you to stand to one side and NOT in
front of or over the tire assembly. Use a safety cage if
available. Do not over inflate tires.
•
Do not weld on or heat a rim. High heat can weaken and/or
warp the rim and damage the tire. Air pressure inside the
tire can increase enough to cause an explosion.
Air Filled Airplane Tires with Split Rims
Figure 5-1
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
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.
