    摘要: An articulated tractor has left and right laterally spaced apart, fore-and-aft extending side frame members which are rigidly attached between front and rear drawbar supports. The tractor also includes left and right draft links, each draft link having a front end coupled to a corresponding one of the side frame members and a rear end for coupling to an implement. A draft force sensing mechanism includes a displacement transducer mounted on one of the side frame members. A lever is pivotally mounted near the transducer and carries a plunger or shaft which operatively engages the transducer. A rod has a first end fixed to the other side frame member and a second end coupled to the lever so that changes in draft force cause deflection of the side frame members and movement of the lever relative to the transducer. The transducer responds by generating a signal representing the draft force. Movement of the rod is amplified by the lever.
