control valve and hydraulic cylinder problems.
Tire Maintenance
!
WARNING
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.
!
WARNING
Always release all air pressure in air-filled airplane tires
before removing hardware bolting their split rims together.
Not doing so can cause the split rims to blow apart instantly
and could result in serious injury or death.
!
WARNING
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 overinflate tires.
!
WARNING
Do not weld on or heat a rim. If a tire is mounted to the rim,
air pressure inside the tire can increase enough to cause an
explosion. High heat can also weaken and/or warp the rim,
damage the tire, and destroy foam filling inside a tire.

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 56.
Refer to Figure 5-12:
3. Replace wheel rims and tires as needed with
genuine Great Plains parts. Do not loosen split rim
hardware (#1) until all air pressure in the tire has
been removed.

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
Great Plains 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 Great
Plains 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
Do not operate cutter with loose pins, bolts, or nuts. Loose
hardware can result in a serious breakdown causing bodily
injury or death.
!
WARNING
Do not alter Great Plains equipment or replace parts with
other brands. Doing so can cause equipment to perform
improperly and may lead to breakage causing bodily injury or
death. Replace parts only with genuineGreat Plains parts.
!
CAUTION
Buildup of debris around moving parts and gearboxes is a fire
hazard. Keep rotating parts and gearboxes free from debris to
avoid serious injury and property damage.
!
CAUTION
Improper oil level can cause bearing failure and be a fire
hazard. Maintain proper gearbox oil level to avoid serious
injury and property damage.
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.
