Maintenance and Lubrication
Maintenance
Proper servicing and maintenance is the key to long
implement life. With careful and systematic inspection,
you can avoid costly maintenance, downtime, and repair.
Always turn off and remove the tractor key before making
any adjustments or performing any maintenance.
Crushing Hazard:
Always have transport locks in place and frame sufficiently
blocked up when working on implement. You may be severely
injured or killed by being crushed under the falling implement.
High Pressure Fluid Hazard:
Check all hydraulic lines and fittings before applying pressure.
Fluid escaping from a very small hole can be almost invisible.
Use paper or cardboard, not body parts, and wear heavy
gloves to check for suspected leaks. Escaping fluid under
pressure can have sufficient pressure to penetrate the skin. If
an accident occurs, seek immediate medical assistance from a
physician familiar with this type of injury.
1. After using your Disk Harrow for several hours, check
all bolts to be sure they are tight.
2. Keep disk scrapers properly adjusted.
3. Clean Disk Harrow on a regular basis. Regular and
thorough cleaning will lengthen equipment life and
reduce maintenance and repair.
4. Lubricate areas listed under “Lubrication” on
page 30.
5. Replace any worn, damaged, or illegible safety
labels by obtaining new labels from your Great
Plains dealer.
6. Always use the manual u-channel transport locks
when working on or doing maintenance to the Disk
Harrow. Read and understand all safety decals on
your equipment.
7. During the first season of operation, and periodically
after that, check your bolts for tightness. Check disk
gang bolts for loose blades. Tighten as needed.
8. Replace or rotate worn parts as needed -- hinge
bolts, clevis pins, bearings, blades, etc. Some Boron
disc blades cannot be rolled to sharpen, they must
be ground. Cracks and breakage will occur if rolled.
The heavy blade option is rollable.
9. Check and tighten any hydraulic leaks. Check hoses
for any leaks replace any leaking hoses. It is
important that there are no leaks on the equipment.
10. Check drag bolts for loosness or excessive wear.
Replace broken or bent teeth. Your drag is an
important part of the tillage operation.
By following and maintaining a routine service and
lubrication program, your tillage equipment will give you
many years of service.
