What model of loader is on your tractor? What bucket is on it now? Are the loader lift cylinders single or double acting? Photos would be a help. I understand the one of the most important things when mounting a plow on a loader is that the plow can float independently of the loader arms so only the weight of the plow is on it and not the weight of the loader arms too. Loaded tires, rear weights, and tire chains are all also a help when snow plowing.
