An improved front hitch assembly is provided for mounting a snowplow to the front of a vehicle. The hitch assembly includes a pair of mounting brackets secured to the vehicle frame, and a pair of receivers releasably connected to the mounting brackets. The plow includes a frame with a pair of horns which are releasably received in the receivers. A pad is provided in each of the mounting brackets and is engaged by each of the receivers to absorb impact forces when the plow hits an object. The brackets include pairs of forward and rearward slots for supporting the receivers in the brackets, with the pads being mounted on the rearward pins. The pads are made of polymeric or urethane material so as to absorb the forces of impact when the plow hits an object.

What is claimed is: 1. A front mount snowplow impact resistance system, comprising: left and right mounting brackets adapted to be secured to a vehicle frame, and each mounting bracket including slots; left and right receivers slidably connected to the left and right mounting brackets by pins extending through the slots and through each receiver; a plow with a frame having left and right horns extending rearwardly and being removably received in the left and right receivers; and left and right impact-absorbing pads mounted in the left and right mounting brackets to absorb forces of impact resulting from the plow hitting an object by compressing the pads such that the receivers slide relative to the brackets, so as to minimize transfer of the impact forces to the vehicle frame. 2. The system of claim 1 wherein each bracket has a rear wall and each pad is mounted adjacent the rear wall. 3. The system of claim 1 wherein each pad has a bushing, and each bracket includes a slot, and further comprising a pin extending through the bushing and slot to mount the pad to the bracket. 4. The system of claim 1 wherein the pads are a polymer material. 5. The system of claim 1 wherein the pads are a urethane material. 6. The system of claim 1 wherein the receivers are free to move rearwardly relative to the vehicle frame upon sufficient force of impact. 7. The system of claim 1 wherein the receivers are not fixed to the vehicle frame. 8. An improved front hitch assembly for mounting a snowplow to the front of a vehicle, the hitch assembly including a pair of the receivers slidably connected to a pair of mounting brackets connected to a frame of the vehicle, and the plow including a pair of horns releasably received the receivers, the improvement comprising: front and rear slots in each bracket sidewall, and front and rear pins extending through the front and rear slots, respectively, and through each receiver to slidably connect the receivers to the brackets; a pad in each mounting bracket and engaged by each receiver to compress and absorb impact forces when the plow hits an object as the receivers slide relative to the brackets; and the pads being located forwardly of the connections between the brackets and the vehicle frame, such that the absorbed forces are not transmitted to the vehicle frame. 9. The hitch assembly of claim 8 wherein the pads are mounted on the rear pins between the sidewalls of the bracket. 10. The assembly of claim 8 wherein the receivers are adapted to slide relative to the vehicle frame during use of the plow. 11. The assembly of claim 8 wherein the receivers are not fixed to the vehicle frame. 12. An improved front hitch assembly for mounting a snowplow to the front of a vehicle, the hitch assembly including a pair of the receivers slidably connected to a pair of mounting brackets secured to a frame of the vehicle, and the plow including a pair of horns releasably received in the receivers, the improvement comprising: a pair of pads mounted in one of the pairs of brackets or receivers to compress and absorb impact forces when the plow hits an object and allow the receivers to slide relative to the brackets; and the receivers being free to slide forwardly and rearwardly relative to the vehicle frame during use of the snowplow. 13. The hitch assembly of claim 12 wherein the pads are mounted in the brackets. 14. The hitch assembly of claim 12 wherein the pads are mounted in the brackets. 15. The hitch assembly of claim 12 wherein the brackets include slots, and the receivers are slidably mounted to the brackets using pins extending through the slots and through the receivers. 16. The hitch assembly of claim 15 wherein each pad is mounted on one of the pins. 17. The hitch assembly of claim 12 wherein the pads are a polymer material. 18. The hitch assembly of claim 12 wherein the pads are a urethane material. 19. The assembly of claim 12 wherein the pads minimize transfer of impact forces to the vehicle frame. 20. The assembly of claim 12 wherein the receivers are not fixed to the vehicle frame.
