SECTION 2 – HYDRAULIC SET-UP (24’ - 28’)

2-36

3. Charge depth control cylinder system.

– Connect depth control cylinder hoses to tractor. Insure that tips and couplers are CLEAN.

– Raise Coulter-Chisel. One cylinder will extend at a time. Do not allow anyone to stand near

Coulter-Chisel 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 Coulter-Chisel plow before next step.

4. Hydraulic hoses and ttings 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 owing out of the cylinder but not owing in.

5. Route hoses along frame and hitch the same way depth control cylinder hoses are routed.

– Stack hoses on top of depth control hoses by using two hose clamps at each bolt.

– Leave enough slack by hitch pivot to allow full range of travel of the hitch without damage to

hoses.
