Title: Transmission for pedestrian-operated tractor
Inventor: TAKIMOTO MASAKANE
IPC: B60K17/04
Filed: 1978-01-10
Abstract: PURPOSE: To easily perform appropriate transmission in accordance with the kind of work, by providing a transmitted torque changing mechanism at the upstream side of the branching part of an axle with a power pickup section.  
     CONSTITUTION: Power is transmitted from the engine of the tractor to an input shaft in a transmission case 2 through a rotary member 11 and a first transmission mechanism 8 incapable of slipping or a second transmission mechanism 9 capable of slipping. Power is transmitted from the input shaft 7 to the axle through a transmission mechanism M. The power pickup part 10 can be spline-engaged with the input shaft 7 to pick power up through an auxiliary chain case 6. Since the transmitted torque changing mechanism 23 consisting of the first and the second trnasmission mechanisms 8, 9 is provided at the upstream side of the branching part of the axle with the power pickup section 10, the transmitted torque can be selectively regulated. Therefore, for instance, the tractor can be smoothly extricated from damp ground.
