PURPOSE:To facilitate mesh shift operation by furnishing a shift lever for main transmission ahead the side of a driver seat, another shift lever for PTO transmission inside of the part behind it, and a third shift lever for aux. transmission outside of the same part. CONSTITUTION:In a tractor equipped with a main transmission an aux. transmission, and PTO transmission, an operational plate 71 to guide the operation of three shift levers is furnished at the side of a driver seat. This operational plate 71 is fitted with three guide grooves; i.e. a one 72 for main transmission in an H-shaped pattern which is positioned ahead, a second 74 for the PTO transmission in I-shaped shift pattern located inside of the part behind it, and a third one 73 for the aux. transmission in a shift pattern different from the first named two patterns situated outside of the same part. As the shift patterns of the shift levers are different from one another, running of the tractor concerned and operation of working machine can be properly made without mistake, and the whole transmission can be constructed light and small. |
