I have a JD 3010 LP. its a really good running tractor, but I have only ran ii on vapor. It does have a liquid handle but have never ran in on liquid. Can anybody tell me if you can run it on liquid and if so what is the advantage. I also read somewhere that if it is a factory standard lp it may be rare and worth more? Any knowledge and help would be appreciated.
 
I do not know what is involved in operating an LP tractor. I believe you are correct in that your 3010 LP is considered a bit on the rare side, especially if it still has the original LP fuel tank that is completely hidden under the hood, rather than a "butchered up" model with a larger LP fuel tank where the hood was cut open to allow for a larger fuel tank. I have gone on a couple trips to look at a 3010 LP tractor to find both to not be original and a "hack job" done on the hood.
 
Yes, you can run on liquid LP for maximum power . It takes warm coolant flowing through the vaporizer / regulator to turn liquid LP into vapor to run the engine.
Back in the day, It was common to run on vapor until the engine was warm, then switch to liquid.

Most modern century or IMPCO LP systems don't even have a vapor valve to allow running on vapor, they have only the liquid valve. They work fine starting on liquid as long as you do not put the machine under a heavy load until the coolant is warm / hot.
 
I have an original one with the factory tank. I have never ran it on liquid. Will get give me considerable more power? I just use it with a small disc to plow food plots. Anybody have any idea what value to the tractor might be?
 
Here in Ohio any and all LP tractors are very rare. Only ones around would be brought in from someplace else by collectors. Only ever was one LP for use around that I ever heard of and it did not stay around long. A Moline and they had to pull it every time to get it started.
 
A few neighbors had LP tractors they used, but that was many, many years ago. They used them for running LP corn dryers in the fall, as the tractor on the dryer could be tied into their 1000 gallon LP tank, too. No need to disconnect the tractor from the dryer and fuel it up multiple times each day. They had "Murphy Switches" on them so the tractors could be run all through the day and night without an operator. That was the only draw for LP tractors I ever saw in Minnesota in my lifetime. These were Oliver and Minneapolis Moline tractors. Cannot say I ever saw any other brands set up to run on LP.
