OK just done that with a Harrison m300 over a sloping lawn . First thing it WILL fall over if you are not very careful . I got mine round the back of house and bolted some very strong bits of wood through the bed held in place with strong rope. If it goes it can only go so far . Pull it on sheet metal as wood will dig in. Get people (strong not a girl) on rope either side of the lathe and use anchor points to steady it . Then pull nice and steady a bit at a time. My first go at this was about 5 years with a Colchester student and it fell over. it took a long time and a lot of effort to get it back up .Don't lift it on the lawn with an engine hoist or similar as it will sink in and the whole lot may go over Good luck .
