If you don't fancy breaking your back and can stretch to about £35 for the day, you can hire a rotavator. Look in yellow pages under 'Tool Hire'. They will probably want a bond as well, which is usually in the form of a cheque for £50 which they give back when you return the machine. Sometimes, they will even deliver and retrieve it all in the price
