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. 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.
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.
