Has anybody ever converted a tractor to run on propane? I have been thinking about doing a propane conversion and wondered how others did their conversions.

Maybe you could adapt a set-up from a RV propane generator .Do you think it would be cheaper then gas ? Al

I once rebuilt a Kohler K 321 for a guy. It was used on a power sweeper in their plant and ran off propane. I didn't get to see how they rigged it up on propane, but it used the stock Carb., maybe only as a air metering valve?? It was very clean inside the engine because propane has no carbon residue like gasoline does.

Most any engine can be run on propane. There are carburetors made for this and they can also be multi-fuel {Gasoline -propane}.
Straight propane engines can be run at a higher compression ratio because it has a high octane rating.

I found this site:

http://www.propanecarbs.com/

It has information on different types of propane conversions, one modifies the existing carburetor, another uses an adapter plate with the original carb and the last uses a dedicated propane carb.

Al, the cost of propane varies quite abit, at least in TN. The cylinder exchange racks are too expensive. Refueling your tank at the local utility or hardware store costs about the same as gasoline. There is one boat and RV center here that is selling propane at a $1.99/gal.

I can understand the benefits of using propane on small engines. Especially ones that are not used for long periods of time.

I wonder if running a small engine without hardened valve seats on propane would cause premature wear on the seats more quickly than running the same engine on the gasohol we have now.
