Abstract
PURPOSE: To make the speed of turning during work proper, and to prevent an engine failure by connecting a travelling car body and the rice-transplanting machine by means of a lifting working mechanism and changing over a stepless variable speed mechanism of a drive system to the low speed side by lifting the rice-transplanting machine.
CONSTITUTION: When the depth of a paddy field varies during work and a soil preparation float 16 rises or falls, an oil pressure changeover valve 30 is automatically changed over, and the rice-transplanting machine 12 rises or falls. When a lever 31 is operated in the direction opposite to an arrow (a) in order to turn the travelling body 1, a wire 48 works a tension pulley 42 in the arrow (b) direction, and a belt 40 is stretched while the oil pressure changeover lever 30 is changed over. Accordingly, the stepless transmission 34 is operated in the deceleration direction and decelerated. Consequently, since the transmission is decelerated automatically when resistance at the time of turning increases, excessive force is not applied to a prime mover 6, and the engine failure can be prevented while an engine is turned at proper speed.
