In that situation, I guess it would make things eaier on you. Plowing snow is one thing, I just would not recommend one for off-road/recreational riding. Concerning the model, a TRX 300EX techincally fits your description, it is a 300cc Fourtrax 2x4, however, the EX is a sport quad. I am assuming that your machine is a utility type quad. It should have a model name like TRX 300 A or TRX 300 AN, do you know which one it is?
