Summary:PURPOSE:To eliminate a trouble to change the fitting position of an angle sensor at the time of every shift of a lower link support point by fixing the angle sensor to the support pin of the turning plate of a three-point link device, and interlocking a sensor arm to a lower link. CONSTITUTION:Support pines 18 are projected from both right and left side walls of a transmission case 5, and a plate 19 is pivotally fitted to each of the support pins 18. In addition, the forward end of a lower link 17 is pivotally fitted to one end of the plate 15 with a set pin 20. Also, a lift cylinder 21 is fixed to the upper part of the transmission case 15, and right and left lift arms 22 are oscillated on the operation of the cylinder 21, thereby moving up and down the lower link 17 connected to a lift rod 23. Furthermore, an angle sensor 26 such as a potentiometer is fixed to one end of the support pins 18, and the tip of the sensor arm 32 thereof is interlocked to the lower link 17 via a connection rod 34 to use the output of the concerned angle sensor 26 for the horizontal control of a tractor for a ground work.
