Troy-Bilt, have been using them since 1973, have worn out two previous 8 hp Horse models. This is the first one since MTD took over. New one a lemon. Poorly assembled (loose nuts/bolts all over it), took it to garden after going over all nuts/bolts, fired it up, engaged tines and instant metal grinding noise from transmission. Into warranty shop with less that 5 min. on it. Depends on what shop says, you may be getting this one back.
