e. Always fully extend the lift cylinders and hold the
lever to ensure the cylinders are rephased before
starting any field operation. This will keep all
cylinders in time and frame sections level when
operating.
f. Servicing – Before servicing any hydraulic
component, lower the implement to the ground
and relieve all system pressure. If a hydraulic
component is disconnected, repaired, or
replaced, it will be necessary to purge the
system of air before operation.
Leveling Hydraulic Disc Gangs
To level the hydraulic disc gangs, first fully extend the
disc gang cylinders and hold the tractor lever at least 30
seconds. This will fully charge and rephase the disc gang
hydraulics.
a. Remove any Stroke control segments and fully
retract all disc gang cylinders.
b. Adjust the center frame cylinder anchors until
there is 9" between the top of the 22" disc gang
blades and the bottom of the frame.
c. Adjust the wing disc gangs to match the center
disc gangs by adjusting the cylinder anchor at
the base of each wing frame gang cylinder. This
will ensure that all disc gangs are set evenly
across the machine.
d. Fully extend and rephase the hydraulic gang
cylinders before starting each field operation.
This will keep all cylinders in sync and gang
depths consistent.
OPERATION AND MAINTENANCE
Stroke Control Segments
Stroke control segments are provided to set the hydraulic
disc gang depth. To adjust operating depth, extend the
disc gang cylinders and install the segments on the
master cylinder rod (left center disc gang cylinder). Set
when the cylinders are extended 2" (approximately 4-1/2"
of stroke control segments), the disc gang will operate at
the recommended 7-1/2" below the frame position.
