Answer: Didn't see the movie, but I looked up the specifications for the John Deere model 200 on TractorData. It was the first of the series and manufactured from 1975-1976. It had a Kohler one-cylinder 305cc 8 HP 4-cycle engine that runs on regular gas and a surprising maximum speed in 4th gear of 7 miles per hour! No one seems to rate lawn tractor MPGs, but similar-sized engines running generators at full load might use about 3/4 to 1 gallon per hour. So, he should be able to go at least 3 and 1/2 hours on a tank, or about 25 miles. He could fill up at a gas station without having to add oil to the gas.
