Propane conversions

Hello,
I have two tractors that I am considering converting to propane. the first is a 1965 Massey Ferguson 85 that has a 4 cylinder perkins gasoline engine, and the second a 1945 John Deere A. I was wondering if anybody has any experience in converting tractors? If so what do I need to perform this conversion? Where can I get the parts? Also what are the pros and cons to doing so?
Thank You
Fred

Interesting subject, This does not have anything to do with your unit, but we have a Propane Laundry Dryer in our home, and I vent it into the garage.

I have been told that this is against the Law, but I cannot find any Law that states Propane Dryers should be vented to the out side in our State.

IF this was the case, then what about our Propane Cooking Stoves and ovens, why is that Not vented to the outside?

we have had our Laundry Dryer vented to the Garage for 23 years, and have not had any problems what so ever.

also, I see many Propane heaters that have NO Vent, or sold as Ventless. seems odd indeed..

The pros and cons are partly related to why would you want to??

Converted tractors were very common out here in west TX, but a lot of the conversions now have butchered hoods, homemade tank brackets, etc...

In other words, do you just want something out of the ordinary? Or do you just want an LP tractor? If so, I'd say it would be easier to just find a factory LP tractor...

just like forklifts.
pros:cheaper fuel,no more ware on cylinders, runs cooler.

cons: pressured fuel tank,25% less power,10%less fuel milage,price about $800.00 kits

Visit your local propane dealers. They may be running trucks on propane and should know who handles the conversion parts and kits. You'll need a vaporizer and a carburetor plus a tank, valves, and plumbing. If there were factory LP options for those tractors the parts book would give plenty details.

Someone out west or south plains areas already has one converted I bet to sell you. JD A would be a aftermarket conversion. The MF 85 I'm not so sure but probably a conversion too. Lots of companies made LPG conversions and parts back when butane blends were cheap but now it's all a propane blend and having to go buy it all to convert you aren't going to save anything. As far as all LPG engines having 25% less power that's a bunch BS talk because a engine built and designed properly for LPG will have just as much power if not more than a diesel or gasoline engine. Why do think the tractor pullers are converting them to LPG ? Leave the engine stock compression for gasoline and don't change the rest it may have less power though. You'll need higher compression pistons, special LPG or cooler running manifold, hard seats for the valves to make one run right to notice much difference or to take advantage of it. Google search LPG or propane conversions and will find lots of places that sell kits. There are many brands you might find on some conversions that parts are no longer made for so make sure it has converter regulator you can get parts for yet. Propanecarbs.com
LPG stuff

got a JD 730 ,720 ,630 ,530 ,60 ,"A" ,"G" on LP & LP is the only way to go...stick with Impco...parts are easy to find ..Google Impco...take care...Kent

The newer systems that use liquid fuel injectors actually gain about 5 to 7 percent in HP without any other changes. By injecting the fuel as liquid into the intake manifold it cools the fuel air charge going into the cylinders so that you get denser air entering the combustion chambers resulting in increased HP.

Last year I read that for every gallon of propane you burn you put .8 of a gallon of water in the air! Might be OK in the desert but here in MN we don't need it! Causes corrosion on vehicles and tools.

And what do you think is the main byproduct when you burn gasoline? Both fuels are hydrocarbons.
