SPEED CHANGE CONTROL DEVICE FOR POWER VEHICLE

PROBLEM TO BE SOLVED: To provide a speed change control device, in which speed change through an accelerator pedal is possible, and in which speed change by manual operation based on the intention of an operator can also be conducted by priority. SOLUTION: This device is provided with main speed gears 10 and 11, an auxiliary speed gear 12, a forward/backward changing device 9, and the accelerator pedal 58. When the auxiliary speed gear 12 is changed over to a position suitable for on-road traveling speed, automatic speed increase/decrease operation to the main speed gears 10 and 11 through the accelerator pedal 58 becomes possible. Even when speed change operation through the accelerator pedal 58 is being conducted, speed increase/decrease operation by operation members 37 and 38 are possible. When a PTO speed gear 70 installed on a frame is at a neutral position, speed change operation through the accelerator pedal 58 becomes possible. COPYRIGHT: (C)2005,JPO&NCIPI
