HST CONNECTING MECHANISM OF COMBINE

摘要

PROBLEM TO BE SOLVED: To ensure positioning of the switching arm of an auxiliary transmission disposed in a transmission case in a combine in which a running transmission HST and a steering HST are arranged on the transmission case, by interconnecting the cases of the running transmission HST and the steering HST by means of an interconnecting member so that their relative positions do not change. SOLUTION: The interconnecting member 110 interconnects the cases of the running transmission HST 60 and the steering HST 90 and an arm pivoting part 110b for connection to the auxiliary shift lever 18 of the auxiliary transmission and the locking part 110c of the shift arm return spring 117 of the auxiliary transmission are provided on the interconnecting member. A side column 16 is positioned above the transmission case 17 and the interconnecting member interconnects the cases of the running transmission HST and the steering HST. The mounting seat 110d of a support frame 116 for the side column is provided on the interconnecting member.
