We have had various discussions about using a petrol cultivator and the health and safety implications. This might include the need for training. There is nothing stop someone from bringing on their own machine. However it is very physical and there is an alternative. We could arrange to hire a worker (who will be insured) to come and do the job. Anyone interested in having their plot done please respond in the comments. We can combine 2 or more plots in one visit to keep costs down.
