i'm sure this has been discussed many times, but i could not find much doing a search. what are advantages/disadvantages of gas/diesel? been looking for @40 hp tractor for a while now and in my head i was settled on a diesel, mainly because of the ethanol issues that could pop up, as tractor would sit for periods of time. but i've seen some good deals on gas tractors and am starting to change my mind. guy down the road from me has a good looking MF 35 gas burner for sale. i stopped and looked at it and told the guy i was interested in a diesel. $3500 which i'm not sure if that is a good price. someone give me some input, please. have seen several MF and fords gas burners on CL that appear to be in good condition.
