I have a Kubota L175 and it has a front snow blade but only turf tires and chains. I don't like chains because they are a pain to get on, they are never tight, and they scrape up the driveway. So I was thinking to getting some ag tires instead. My concern is that they still won't give me good enough traction and I will have to use chains anyway. However, last year, I did plow about 6" of snow and with some rough spots and a little fairy dust, everything worked fine. That was with an approx. 450 lb. rototiller on the back, so if I get the ag tires, put calcium or other weight in them, and put on my 600 lb. woods mower, I think it would probably work pretty good. But my other concern is where to get ag tires that are in good shape and the cost. Please give me suggestions.
