Adapter Mounting Instructions
for John Deere Combines
PREPARING THE HEADER
1. John Deere (all models except 60 Series Combines):
• Attach the hydraulic/electrical completion package as follows:
• Two coupler brackets are provided with the adapter for John Deere
combines, as hydraulic connections are made at both sides of feeder
house.
• Mount the coupler bracket with one pre-mounted coupler to the inboard
flange of the left header leg with two 1/2 x 1 inch carriage bolts and
flange nuts at (A). (For 963 Header, coupler bracket bolts to a bracket
welded to the header back tube near left side of opening.)
• Attach brace (D) to coupler bracket (F) using 1/2 x 1 inch carriage bolt
and flange nut at (G). Ensure brace (D) is tight against backtube and
bottom of coupler bracket. Tighten bolt (E) and jam nut after tightening
brace to coupler bracket. Bolt (E) should be tight enough to ensure L/H
leg of brace is tight against backtube.
• For headers with optional hydraulic reel fore-aft/header tilt options,
install red & green couplers and spacers (D) to coupler brackets as
shown: Green to left and Red to right.
• Match the coloured cable ties to connect the header hoses to the left
hand coupler bracket:
Reel Fore-Aft/Header Tilt – Green to Green – top coupler.
Reel Lift – Black to Black – lower coupler.
• Mount the Reel Fore-Aft/Header Tilt selector valve (B) (if equipped) to
the left hand coupler bracket with two 1/4 x 2-1/2 inch hex bolts and nuts.
• Mount the other coupler bracket with two pre-mounted couplers to the inboard flange of the right header
leg with three 1/2 x 1 inch carriage bolts and flange nuts at (C). (For 963 Header, coupler bracket bolts to a
bracket welded to the header back tube near right side of opening.)
• Match the coloured cable ties to connect the header hoses to the right hand coupler bracket:
Reel Drive – Yellow to Yellow and White to White – two lower couplers.
NOTE: For 2-arm headers (21’ & 25’) pull the reel drive hoses out of the centre channel and route to
the R/H coupler bracket. Shorten hoses to fit and attach to re-usable hose ends supplied.
For 3-arm headers (30’ & 36’) detach the yellow and white tagged hoses shipped on the coupler bracket. Re-
route the existing reel drive hoses on the header to the R/H bracket and connect.
Reel Fore-Aft/Header Tilt – Red to Red – top coupler. Route this hose across header opening from left
leg to right. Tie to hydraulic lines or hoses for best appearance.
