Layout structure null of the chain drive case in the farm working

摘要

PROBLEM TO BE SOLVED: To obtain arrangement structure by which structure is simplified, a remaining tillage processing in the lower part of a chain transmission case is simultaneously executed with a wheel mark processing and work efficiency is improved by arranging the chain transmission case in the rear part of the tractor wheels. ;SOLUTION: An agricultural work machine length direction center part 4 is mounted on the rear part of a tractor with three-point link hitch mechanism so as to be elevating/lowering possible and driving power is transmitted from the tractor to the agricultural work machine center part 4 in the agricultural work machine. In the machine, a chain transmission case 9 for transmitting driving power which is transmitted to the upper part of the agricultural machine as against a work part which is provided in the lower part of the agricultural work machine is arranged in the rear part of the tractor wheels T. Besides, it is favorable that the agricultural work machine is tri-sected into the center part 4 and left and right work machine parts 5L and 5R, the left and the right work machines 5L and 5R are made to be foldable as against the center part 4 and the chain transmission case 9 is provided in the center part 4.;COPYRIGHT: (C)1998,JPO
