I installed these weights on my 42" Craftsman Professional Garden Tractor for use while plowing snow. First, I do not understand why one user complains about the installation process -- I installed the weights in my garage, wheels on the tractor, in 18 degree temperatures (so I was in a hurry) and had no problem doing so. Possibly the person that had installation issues did not have the proper tools. Second, my driveway is over 130 feet long, with a curve, and slopes down to the street -- to date, it has not been necessary for me to use tire chains, despite the fact that Sears did recommend use of chains, and traction has been great!
