Maintenance and Lubrication
Maintenance
1. Always use the transport lock when working on or
doing maintenance to the Discovator. If folded, be
sure your wing stop pins are in place. Read and
understand all safety decals on your equipment.
2. During the first season of operation, and periodically
after that, check your bolts for tightness. Check
shank pivot bolts for tightness. Check shank pivot
bolts on the spring-loaded shank, these must remain
tight to prevent excessive wear on the shank assem-
bly.
3. Replace or rotate worn parts as needed -- hinge
bolts, clevis pins, bearings, sweeps, shanks, etc.
Boron disc blades cannot be rolled to be sharpened,
they must be ground. Cracks and breakage will
occur if rolled.
4. Check and tighten or replace any hydraulic leaks.
Check hoses for any leaks. It is important that there
are no leaks on the equipment.
5. Grease wheel bearings and walking beams spar-
ingly. Over greasing may cause damage to seals and
reduce the life of the bearing. Grease hinge points
periodically.
6. Check drag bolts for loosness or excessive wear.
Replace broken or bent teeth. Your drag is an impor-
tant part of the tillage operation.
7. If machine is stored outdoors over the winter months,
it is a good idea to fold the machine then set it down
on the ground so all the cylinders are retracted to
protect the cylinder rods. This will extend the life of
the cylinder seals and reduce internal and external
leaks.
By following and maintaining a routine service and lubri-
cation program, your tillage equipment will give you
many years of service.
