Hi Chris and Mod CJ,
My only objection to the Rover Thoroughbred is that the rear roller has a sharp edge to it which is an issue with it turning up the lawn nap when turning sharper corners as one has to do in the normal garden, thus the rear roller on the SB Model 45 is far forgiving with a radius-ed edge IMHO.
I have wrecked out about 3 of these and the only thing I've hung on to is the 3 Hp power plant which uses a 3/4 inch size PTO shaft opposed to the much more common 5/8 unit. Also finding a catcher is also rather trying I must ad with them being plastic units.
Cheers,
BB.
