3. Charge depth control cylinder system.
– Connect depth control cylinder hoses to tractor. Insure that tips and couplers are CLEAN.
– Raise chisel plow. One cylinder will extend at a time. Do not allow any one to stand near
Chisel Plow when it is raised or lowered.
– When all cylinders are fully extended, fully cycle the circuit four times to make sure all air has
been removed from system.
– Lower chisel plow before next step.
4. Hydraulic hoses and fittings for wing lift cylinders are shown in the following drawing.
– The wing lift hydraulic circuit is equipped with a one-way restrictor to prevent free fall of the
wings when being lowered. Be sure that the restrictor is installed so the arrow points toward
the cylinder. This will restrict oil flowing out of the cylinder but not flowing in.
– For 38’ and larger machines, 5 x 36” cylinders are used.
