7. Hydraulic Hose Connections:
910 Series Headers: No hydraulic connections
between header and tractor. Couple (A) to (B)
and (D) to (E) for these units. Failure to do so
will cause header drive circuit to overheat,
causing potential hydraulic component failure or
product performance problems.
920 & 930 Series Headers: Two connections
are made at couplers (A) and (B) at the header
right hand leg. One connection is made at
coupler (D) at the header left hand leg. For 912
& 922 Headers with Hay Conditioner equipped
with Hydraulic Roll Opener cylinders, connect
hose from these cylinders at coupler (C).
940, 960 & 970 Series Headers: Two
connections are made at couplers (A) and (B) at
the header right hand leg. Two connections are
made at couplers (C) and (E) at the tractor left
hand leg. One connection is made at coupler
(D) at the header left hand leg.

B - reel drive return
C - reel lift (or Hay Conditioner Roll Opener
cylinder circuit, if equipped)
D - conveyor drive pressure
