OPERATION AND MAINTENANCE
Leveling (Side to Side)
1.
An adjustable radius rod connects the center frame
lifts together to keep them operating in unison. The
radius rod does not level the center frame lift. The
radius rod length is determined initially by fully
retracting the lift cylinders and adjusting the radius
rod until it is loose and tightening the jam nuts.
2.
To level the center frame:
a.
Verify that all of the tires are properly inflated.
b.
With the unit unfolded, raise it to fully extend the
lift cylinders and continue holding the tractor
lever 30-60 seconds to insure the cylinders are
fully extended and the rephrasing lift system has
been purged of air.
c.
Lower the unit so the disc blades are 1” off the
ground.
d.
Measure the distance from the walking beam
spindle to the top of the frame on both sides. If
there is a difference, it needs to be adjusted by
turning the cylinder rods with the wrench flats
provided at the clevis end
e.
Let the machine down onto the ground to relieve
any pressure, but do not fully retract the
cylinders.
f.
Loosen the set screw in the cylinder rod block. If
the difference is 1/4” this requires turning the rod
of the short side one full revolution to lengthen
the cylinder. If the difference is 1/2” this requires
turning the rod of the short side out one full turn
and the rod of the tall side in one full revolution.
Any differences of less than a 1/4“ are
acceptable for operating.
