作業車の電子制御式自動変速装置。 Accelerator sensor 1 that detects accelerator operation amount
1 and a vehicle speed sensor 12 that detects the actual vehicle speed. The electronically controlled automatic transmission for a work vehicle is provided with a control device 13 that determines a shift point of an automatic transmission mechanism 5 based on the detection result of a vehicle speed sensor 12 that detects the actual vehicle speed. A manually operated sub-shift mechanism 6 is provided in series with the control device 13, and the control device 13 is controlled so that the shift point is at the second shift point by cutting off the power supply.
An electronically controlled automatic transmission device for a work vehicle, which is configured to be set to a low speed position, and is provided with means for cutting off power to the control device 13 in conjunction with switching of the sub-transmission mechanism 6 to a low speed position. .
