つ張り操作が行い難くなる問題点があつた。 Conventional rope starting devices for engines mounted on agricultural machinery are known, for example, from Japanese Utility Model Publication No. 50-25613 and Japanese Utility Model Publication No. 51.
As seen in Publication No. 59724, the belt transmission mechanism that transmits power from the output shaft of the engine to the traveling transmission of the agricultural machine is structured to be installed separately from the belt transmission mechanism, so each is covered with a separate safety cover. The problem is that the number of required parts such as mounting seats for fixing each safety cover increases and the overall structure becomes complicated.Furthermore, the rope starting device itself has a rope attached to the rear in the longitudinal direction of the aircraft. The rope is started by pulling the rope, so if a large diameter wheel such as a wet field wheel is attached to the transmission axle, it will be difficult to pull the rope due to the influence of the large diameter wheel. A problem arose.
