Hello all, I just bought a new L3800 tractor with the front end loader, a snow plow and a box scraper. The dealer told me that I would need chains for plowing snow which I bought, a set of walco chains. Today I tryed to install the chains but they rub on the inner fender. Not much clearance there...am I doing something wrong? Do I need wheel spacers to clear the chains? Thanks for any help.
