Abstract

PURPOSE:To reduce the operating load by turning a control lever kept at a neutral position to the right or the left to set it at a forward or backward moving position for interlocking with a hydraulic control part via a forward or backward moving system attachment/detachment arm and turning the controlling lever along a forward or backward system stepless speed changing groove to secure a stepless speed changing operation. CONSTITUTION:A control lever 16 kept at a neutral position N is turned to the right or left in a forward/backward switching mode. In a stepless speed changing mode the lever 16 interlocking a forward or backward moving system attachment/detachment arm 26 or 27 is turned forward and backward along the corresponding forward and backward moving system stepless speed changing grooves 21 and 22. Then an hydraulic operation is carried out via a hydraulic control part 32. Thus it is possible to perform a stepless speed changing operation in an easy and smooth way without increasing the operating load of the lever 16 in a stepless speed changing state.
