873 Combine Adapter Pre-Delivery Checklist
ADAPTER SERIAL NUMBER
Perform these checks and adjustments prior to delivery to your customer. See the Operator's Manual for
adjustment details.
CAUTION: Carefully follow the instructions given. Be alert for safety related messages
which bring your attention to hazards and unsafe practices.
‰ Check for shipping damage or missing parts.
‰ Check float spring and down stop configuration. Adjust to suit header/combine combination if necessary.
(P. 39)
‰ Check that position of adapter side deflectors aligns with the feeder house opening on combine. These
deflectors direct crop flow smoothly into the feeder house opening. This prevents crop from hitting and
building up at the “wall” created by the faceplate at each side of the feeder house opening. (P. 41)
‰ Check that feeder draper is under draper seal at sides.
‰ Check feed draper tension. (P. 42)
‰ Ensure feeder pan and skid plate are properly assembled for your header/combine combination. (P. 43)
‰ Install linkage supports in header lower legs (972, 973 Headers Only). (P. 47)
‰ With the float arms sitting on the stops, set float adjustment to 50 lbs. (225 N) when lifting each crop
divider for above ground cutting. Set float adjustment to 30 lbs. (135 N) when lifting each crop divider for
cutting on the ground. (P. 18) [50 lbs. = approx 6 gal. water (22 L) / 30 lbs. = approx. 3 ½ gal. water (13L)]
‰ Check that rear of feeder draper moves up and down freely.
‰ Set center link to mid-range length of 19-1/4” (490 mm) pin-to-pin. Check that locking collar on mechanical
center link is tight against tube. (P. 44)
‰ Move retracting tine drum to correct position for header and combine model. (P. 45)
‰ Check gearbox oil level. (P. 31)
‰ Loosen breather screw on hydraulic reservoir cap. (P. 17)
‰ Check hydraulic reservoir oil level. (P. 29)
‰ Set draper flow control to number 4. (The number at the top of the dial is the setting.) Run header drapers
slowly for 5 minutes to fill hydraulic lines, then check oil level at adapter reservoir. (P. 17)
‰ Grease all bearings. (P. 26)
COMBINE:
‰ Position front drum down and forward.
‰ For optimal performance, remove bolt-on dust shields.
‰ Use feeder chain with aggressive (serrated) bars if available.
‰ Adjust face plate (if adjustable) to optimum angle. (P. 50)
