I bought my rotovator off e-bay it's a 73 Mountefield but with a re-con Briggs&Stratton 5hp Quantum engine and it does a great job, I have also bought a set of traction wheels and engineered my self a ridging plough and a set of hoe's and I must say it has saved me loads of time, last week when I had to do some more heavy digging(65sq metres) yesterday I went to the lotty with the rotovator and broke it all down, if I can get on in the next day or so I will ridge it up and put some more spuds in, so whatever you buy go ahead and make the purchase :)
