4010 LP Question

schultz47 · Posted: Fri Jan 11, 2013 7:04 am Post subject: 4010 LP Question

With all the LP questions on here I thought I would ask. A few years back tried to use a friends 4010 LP when my tractor quit. It didn't have enough power to pull a 4 bottom semi-mount plow, or a Vermeer round baler. When it started pulling hard it would start to misfire and lose power. He filled the tractor from his LP tank with a hose off the top. Wondering if that was the problem, he was only getting vapor and no liquid in the tractor? Tractor started and ran good until you put a load on it.

The 4010 system, like any properly installed LP system, will have two valves, one liquid (off the bottom of the tank) and one vapor (off the top of the tank), and when LP is pressurized, it will liquify, even if it is introduced in a vapor form, or is introduced in liquid form into the top of the tank (which is normally the only way you can fill the tank.) Do you remember whether you switched it to liquid once you started it? Normally they are started on vapor and then switched to liquid within a few minutes. But nevertheless, it should have run okay to pull a four bottom plow or a baler, vapor or liquid. Sounds like a problem with the system that needed professional attention, not anything that you did wrong. Just sayin'.

wonder if it could be something in the ignition system. Bill

probably ignition problem. the propane system very seldom is the problem but it always gets blamed first. propane needs a hot spark. missing under load is almost always cheap plug wires, bad plugs{dont use champions}, or worn points. if the propane system has a problem you should notice it when it is not under load also.

I had a 4020 LP and overhauled it. In reading the manual it said to put the flywheel at the TDC position and do this and do that.

I had every JD jock in the county out here trying to figure out why it just wouldn't work to no avail.

One day I decided to go back to the manual and read through the setup again and WALA. A one liner that said: "When you have finished with the preceding procedures, SET THE TIMING TO 25 DEGR. BTDC...........................DUHHHHHHHHH!!!!!

That was that.

My personal experience with that fuel was very disappointing. The tractor was very picky and was hard to start after running. The fuel ran hot and sitting in the open station, as compared to a comparable diesel was extremely uncomfortable in the summer.

I had a nurse tank on wheels that I towed around to service it. In the summer, when working the tractor, unlike diesels I had later, it had to be refueled at least twice a day and to refuel a propane tractor in 100 degree heat with the engine hot was more than I could stomach.

I fired it.

You sure got that right--all of it.

Something that seems to always be ignored is the strainer in the lockout solenoid. The fibers of the filter plug up with rust as well as ice if there is a restricion.

Yes, always started it on vapor and then switched to liquid.
