SECTION 2 – HYDRAULIC SET-UP (32’-40’)
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.
– For 36’ & 40’ machines, 5 x 36” cylinders are used.
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.
