WALKING TYPE FARM CONTROL MACHINE

PURPOSE:To simplify a mechanism and a structure inside a transmission case as well as to aim at reduction in the cost of production, by interlocking and connecting an input shaft of the transmission case and an output shaft of an engine together in series via both disc type and belt type stepless transmissions free of transmission in c.w. or c.c.w. rotation. CONSTITUTION:An output shaft 5 of an engine 2 in front of a machine body and an input shaft 21 of a transmission case 4 pivontally supporting a traveling wheel at the central part are interlocked and connected together in a series via a disc type stepless transmission A and a belt type stepless transmission B. And, selection of c.w. or c.c.w. rotation and a transmission ratio range of about 1:4 at the c.w. rotation are set up by the disc type stepless transmission A, and furthermore in conjunction with a transmission ratio range of about 1:3 at the belt type stepless transmission B, an axle revolving speed is set up in an almost necessary range. In consequence, shift gearing and gear self- disengagement prevention are no longer required, whereby at the inside of the transmission case 4, deceleration alone takes place. Therefore, the transmission case 4 is extremely simplified in structure and, what is more, the cost of production is reduced.
