If your show next year on on a well kept grass playing field then you should be OK, long grass on a farmers field/paddock will likely be a challenge and in either case wet weather could see you bogged down. A small engine will almost certainly need constant attention to keep the fire going and water at the right level so don't hope to be able to leave it parked outside the beer tent gently ticking over for half an hour.
