Hi there from a wet Leicestershire,
I am still considering getting a rotovator for my plot along with the other helpful suggestions from the forum.
One brand of rotovator I have seen on Ebay is the 6.5hp maxtra heavy duty model from a company called Direct Power. It looks quite a sturdy bit of kit for the money but I would be grateful to hear opinions from anyone who has used or owns one of these machines. I haven't heard of this brand before but then I haven't been looking that long :

Have a good day,
Digger.
