Summers Superchisel - 5-Section - Manual (Page 31)

SECTION 2 – HYDRAULIC SET-UP OF DEPTH CONTROL CIRCUIT
NOTE: The Summers Superchisel uses rephasing hydraulic depth control cylinders. Oil from the
rod end of largest cylinder travels to the base end of second cylinder and so forth. It is very
important that all hoses are routed correctly or machine will not operate properly.
Helpful Hint: Leave rubber backed clamps and plastic clamps loose at locations where depth control
hoses will use the same bolts as wing lift hoses. (Wherever there is more than one clamp,
wait to tighten until wing lift hoses are installed.) See page 2-21 or 2-22 for Depth Control
layout.
1. It is best to start by routing the 3/4” hose for the 6 x 10” cylinder.
– Route hose along hitch frame. Use rubber-backed hose clamps provided. Do not tighten until
routing is complete.
– Rubber backed clamps will be placed on top of plastic hose clamp bolts. Install correct quan-
tity of plastic clamps before installing rubber backed clamps. (2 plastic clamps per bolt are
needed on the hitch and front center section. 3 plastic clamps per bolt are needed on rear
center section. 1 plastic clamp is needed on right hand rear cylinder attach.)
– Plastic clamps are made to have the round surface point towards the surface that you
are mounting to.
– Leave plenty of slack by hitch pivot. The hitch pivot point will move up and down from
transport position to field position. Hoses must be loose enough to allow full range
of motion.
– Continue to route 3/4” hose to front center cylinder. Bolts welded to the frame show routing.
Attach this supply hose to the port that is connected to the poppet valve.
2. Route 1/2” hose from the 6 x 10” to the 5-1/2 x 10” cylinder along center section.
– Route hose under transport lock and up the right hand rear center cylinder attach bracket to
the 5-1/2” x 10” cylinder.
– This hose must be attached to the base end (top) of the 5-1/2 x 10” cylinder.
3. Route 1/2” hose from the 5-1/2 x 10” to the 5 x 10” cylinder.
– This hose must go from the rod end (bottom) of the 5-1/2 x 10” to the base end (top) of the 5
x 10” cylinder.
– Route this hose under transport locks.
4. Route 1/2” hose from the 5 x 10” to the 4-1/2 x 10” cylinder
– 2 plastic hose clamps should be installed by the left hand rear transport lock and at points 2
and 3 on drawing.
– Leave slack between points 1 and 2 to keep hose from stretching during folding and
field operation.
