This is just for residential use, but I would appreciate the advice anyone would be willing to provide. I am considering purchasing a slightly used (40 hrs) Scott's 17.542 lawn tractor (made by JD). It includes a pull cart and 46" snow blade. I have a few concerns: Does anyone have experience using a blade with this size engine (17.5 HP Kohler)....is this enough HP to do a decent job? Wouldn't rear weights and/or chains be needed? Is the Scott's brand still on the market as made by JD? If not, would it be difficult to get service? Anyone had experience with the Scott/JD tractors....how was the reliability? Maybe similar to the JD brand sold by Home Depot? (i.e. questionable quality) Thanks for the help!
