Abstract: In a snow removal machine, an adjustable snow directional discharge device having an upwardly directed snow discharge chute rotatable about an upright axis of rotation, a deflector pivotally mounted on the upper end of the chute, a retractor urging the deflector towards an upper position, a support bracket having a fixed bearing surface mounted on the axis of rotation of the chute, and a means for adjusting the deflector to lower positions including a lever secured to the deflector and a control cable extending between the lever and a rearward control station and passing over the bearing surface.

Abstract: A vehicle, such as a tractor, having propelling wheels connected by a differential, together with a traction control device for connecting the propelling wheels directly when the differential permits relative motion between the propelling wheels, including a rotatable shaft having friction rollers secured thereon at axially spaced positions to engage the propelling wheels, lever means pivotally mounted on the vehicle chassis and having bearings for supporting the rotatable shaft, and handle means connected with the lever means for moving the friction rollers into contact with the propelling wheels.

Abstract: A vehicle, such as a tractor, having propelling wheels connected by a differential, together with a traction control device for connecting the propelling wheels directly when the differential permits relative motion between the propelling wheels, comprising a torque transfer assembly including a rotatable shaft, friction elements fixed on the shaft spaced apart axially to engage the propelling wheels, and bearing means for supporting the shaft, resiliently flexible support means secured on the vehicle chassis and connected remotely to the torque transfer assembly to permit movement of the assembly between an inoperative position and an operative position and an actuating means adjacent the operator's station and secured to the support means to move the assembly to an operative position. Preferably the resilient support means urges the torque transfer assembly toward an inoperative position.
