what about a different head that somebody has for parts IJ we have a awesome 920 head only 1000 acres onit !we just bought 9600 and a 1998 930 contour master ! maybe you can help me this head doesn't have the pto shafts to hook it up too the combine ! our combine is not a contour master we don't need it but the head was cheap and the best at the auction less then 10,000 for it we like the pto hook ups and are wondering if we can make it work withouta lot of trouble ! the coupling chains always get stiff even if we soke then in oil ! thanks for your time !
