Maintenance and Lubrication
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 on the
spring-loaded shank; these must remain tight
to prevent excessive wear on the shank
assembly.
3. Replace or rotate worn parts as needed—
hinge bolts, clevis pins, bearings, sweeps,
shanks, etc...
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
sparingly. Over greasing may cause damage
to seals and reduce the life of the bearing.
Grease hinge points periodically.
Wheel Bearings
Grease every 50 hours (sparingly) and
check for endplay.
All Hinge Points
Grease every 10 hours.
Walking Beam Pivot Bearings
Grease every 100 hours (sparingly) and
check for endplay.
Disc & Coulter Gang Bearings
Grease every 50 hours (sparingly).
6. Check drag bolts and parts for looseness or
excessive wear. Replace broken or bent teeth.
Your drag is an important 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 of 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
lubrication program, your tillage equipment will give
you many years of service.
