Reversible snow plow attachment for wheeled vehicles

Abstract

Abstract A reversible snow plow attachment for wheeled vehicles is provided in which a generally U-shaped frame is detachably connected to the vehicle by a trunnion mount which is located under the vehicle and to the rear of the front wheels. The frame includes straight drive bars on each side pivoted to the trunnion and extending forwardly outside of the ''''cramp'''' line of the front wheels. A mold board is pivotally connected to the frame to swing rearwardly to either side for reversible plowing. The mold board is especially long and arranged so that the resultant forces during plowing pass through or near to the center of traction of the wheels. Special arrangements are provided for high speed plowing with a long mold board including lateral abutment between the board and the frame for side plowing, and including a bridge structure on the back of the mold board which sandwiches the frame above and below and both supports the board longitudinally and restrains it from tipping forward or backward. The position of the trunnion mount is low and the drive bars transmit their force to a low point on the mold board. This improves the structural arrangement of the supporting elements against tipping of the board, and it minimizes the tendency of the board to lift the front wheels during plowing. Since the front end of the vehicle is not used for supporting the plow, the mold board can therefore be close to the wheels. Also, for vehicles having front end loader attachments, plowing can be done without removing the bucket, and the bucket can remain full, also improving traction. Standard hydraulics can be used for reversing the blade angle, and for lifting the blade.
