I gotta tell you, since I bypassed the seat kill switch and I added wheel weights to the lawn tractor, I have really enjoyed the thing. The 4500 feels a lot more stable when on a slope and when towing the lawn sweeper the traction is way better. If anyone is considering weights for this model, go for it. I think I might also want to go with a wider tire, this thing only has 8 inch width tires on the back, my fathers Husqvarna has 10 inch tires, but what benefit would it really give me? around here they are about $60.00 each, and I gotta figure they are a pain in the butt to change, or I could take them to the garage so they can do it..
