Never heard of suitcase weights and I've had tractors a looong time. If Digger has them and if I was plowing snow, would buy them. Great idea, easy install.I had a bracket made to hold 4 small suitcase weights (40 lbs each). I have another bracket for the front, made from an old mule drive, so I can use the same weights on front for plowing with the moldboard plow. I also have a pair of the cheap plastic wheel weights, and 2-link chains, to go along with my 275 lbs of bodyweight, so traction is not a problem. lol.
