I have a John Deere 335 that is in excellent condition other than the hood which is completely gone. I have been looking for a used one but not having much luck. I ran across a 345 that has a brand new hood but the engine is shot. My questions: Are there any differences other than the engine between the 335 and 345. If not, would the hood off of the 345 work on the 335? Would the engine from a 335 fit on the 345 if there are other features on the 345? I can pick up the 345 with new hood and good seat for less than it would cost me to buy a hood for the 345.
