Maintenance and Lubrication
1. Always use the transport lock when working or
doing maintenance on the Field Cultivator. 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. Check wheel bearings occasionally for
excessive endplay.
4. Replace or rotate worn parts as needed—
bearings, sweeps, shanks, etc...
5. Check and tighten or replace any hydraulic
leaks. Check hoses for any leaks. It is
important that there are no leaks on the
equipment that may change the depth when in
field position.
6. Grease gang bearings and wheel bearings
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.
Walking Beam Pivot Bearings
Grease every 100 hours and check for
endplay
All Hinge Points
Grease every 10 hours.
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
that may cause future problems maintaining a
level machine.
8. 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.
By following and maintaining a routine service and
lubrication program, your tillage equipment will give
you many years of service.
