POWER TRANSMISSION APPARATUS AND AGRICULTURAL WORKING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide an agricultural working machine having simple structure and capable of adequately suppressing the decreasing of the durability of an engaging body and an engaged body. SOLUTION: A foldable agricultural working machine is provided with a cultivation axis 53 rotating by driving power and another cultivation axis 88 which turns in the direction parting from the cultivation axis 53 corresponding with the folding motion of the machine body 2 and turns in the direction approaching to the cultivation axis 53 corresponding with the fold-releasing motion. The cultivation axis 53 has an engaging body 68 for power transmission and for axial alignment. The other cultivation axis 88 has an engaged body 105 which transmits driving power from the side of the cultivation axis 53 to the side of the other cultivation axis 88 by the engaging with the engaging body 68 and aligning a rotary central axis X1 with a rotary central axis X2.
