Abstract

PURPOSE:To aim at executing safe control of a farm tractor and as well to simplify the control by forcedly changing a transmission unit to a low speed position when it is set in a high speed position upon an advancing and reversing mechanism being set in a reversing position. CONSTITUTION:Switches S1, S2, S3 are provided in an advancing and reversing mechanism 5, and transmission mechanisms 6, 7, respectively, a control lever 12 or 15 of the transmission mechanism 6 or 7 is provided with a mechanism for forcedly changing the transmission mechanism to a low speed position. The forcedly changing mechanism is actuated when a reversing position and a high speed position are set, so that the low speed position is set for preventing the tractor from reversing at a high speed, thereby the safety is improved.
