nath,
I have 5 of them here at the moment, one has a Kawasaki motor on it, 2 have Tecumesh and 2 have Briggs. One has the fixed front wheels. One I picked up a couple of days ago had been in the weather for some years. The transmission was rusted up badly (every bearing rusted solid. Took a while to get it all stripped down but with new bearings it is better than when it left the factory as I have fitted proper sealed bearings to the axle, not the flanged pressed metal ones the factory fitted. Once the transmission is rebuilt on these, put a new motor on it and you have an industrial grade piece of farm equipment, not just a self propelled mower. These are for serious people who want something to last them many years not just some cheap mower from a Hardware store. The drive gear in these makes the Honda self propelled look like some cheap Chinese rubbish. I had a bloke come here last week saying he bought 2 new Hondas at $1900 each. I told him to treat them with kid gloves because the transmissions are a disgrace
