| Old friend from the dirty jersey called me yesterday. An estate near him is cleaning up and has a 190xt gas they want gone. ( too newfangled for me) did they make a lot of them with a gas engine? Got to be the most powerful tractor i have ever heard that is gas? |

| 190XT gas was 89 PTO HP. Deere 4020 and IH 806 gassers were in the 93 to 95 HP range. |

| So lets say something for reasons that don't make any sense wanted to try and start this tractor. It is under cover but hasn't run for years. What would you do? I am thinking 1. Change the oil 2. Drain the gas 3. Rebuild the carburetor 4. Change the plugs. Anything else? |

| Points will need filing. |

| If it was me, I'm cheap. I don't know anything about the tractor. Loosen the oil drain plug to the last thread and let out a couple of ounces, looking for antifreeze. If none...screw the plug back in, the oil is OK to start it. If antifreeze is there keep draining until you get nothing but oil and then tighten the plug. Hang a gas jug with a rubber hose up high and connect to the carburetor inlet to gravity feed it, bypassing the fuel pump. Crank the engine while someone holds the coil wire close to the cylinder head and see if there is good spark or not. Got spark?? try and start the engine.No spark?? new points or whatever it takes to get spark. You'll need a good battery I'm sure. |

| I love my 180 gasser, which had the same engine as the 190 gasser (non XT), and a very similar engine to that in the XT. A farmer near our Northern farm has a 190 gasser (non XT) and it's sure a sweet-running unit. With the price of diesel being so much higher than gas these days, I'd be happy to find another 180/190 gasser. If you're using one on a really heavy load like primary tillage, it certainly sucks back the fuel and is still perhaps a little more costly to run than a diesel. But if you're using one for lighter work (mowing, baling, etc.), I find the fuel use doesn't vary too much from a similar-sized diesel. Couple that with how simple and smooth those engines run, and they make for superb tractors. |

| 8.0 GPH for the XT gas @ 89 HP. 5.7 GPH for the XT diesel A 93 HP. Probably not much savings on the diesel at todays prices. |

| From the very little I've run the diesel next to the gas. The diesel is much louder and diesel sounding. Running it all day would drive me nuts. Gas is a bit quieter and not so rumbly smoother, I have run it for at least half a day and haven't gone crazy. |

Yup. I use a portable outboard motor gas tank with the little rubber squeeze priming bulb for starting anything old that has a questionable fuel system. I do use 2-stroke chainsaw mix as I believe it may help with initial lubrication of the top end, and I am confident that it does no harm.

If I’m not mistaken, IH did have an 856 gasoline. ------------- I tried to follow the science, but it was not there. I then followed the money, and that’s where I found the science. |

| Oliver 1850 and 1855 gas were 92 HP. Both 310 cubic inch engines. Almost 8 GPH at full load. |

| Going to go down next week and give it a try. Also found this cool antique wooden allis thing a mo bod. Will try and get a ten year old to teach me how to post pictures |

Yes they did. MM had the G-950 gas with 426 CI and propane models with a 504. Moline Dan on YouTube has a G950 gas with .030 (I think) over jugs from a 504. That's about 525 CI of gas loving engine! Glad I'm not buying the fuel for that!

According to my Nebraska Tractor Tests book the M-M G-1000 on propane at full boogy would burn nearly 10.5 gallons of LPG per hour!  |

My wife has acquired a Minneapolis Moline G 1000 Wheatland LP. Sounds like it's a good thing it's not going to be the main workhorse on the place Darrel |

Reckon it all depends upon the price and availability of LPG vs Gasoline vs Diesel. It is nice to have options. |

Oliver/Minneapolis Moline also made a 4wd tractor with an 8.3L LP engine. 169 HP. Low production. Territorial Trading on Youtube has one that he's made a couple videos on.

| Versatille model 125 tractor used a Ford Industrial model "391" engine. The 361/391 Industrial engines are often confused with 360/390 car/pickup engines. The Industrial engines have steel crankshafts, sodium filled exhaust valves, double roller chain and steel cam and crank timing gears, forged pistons and a longer crankshaft pulley system to be able to power pumps and air compressors. While still part of the "FE" family, they are clearly different than car engines. |

| Thanks for the updated information Dr. I believe those engines were used in the heavy trucks also. |

| Yes. Probably more in medium/heavy duty trucks than any other application. Then the big block 401-477-534 Super-Duty engines were the big dogs. |

I had a Ford L7000 Louisville with a 391 great motor and about the best driving big truck for that era.Got very good gas mileage too.

I had a 190XT gas a few years back and was going to turbo it - Doc answered back and said well, if you do - it burns 10 gallons/hr now - you will probably be a 12 + GPH. I sold the XT gas.. :-) ------------- When told "it's not the money,it's the principle", remember, it's always the money.. |

| Motor is free but i couldn't get a spark past the coil. Oil had just a little condensation. Boy, that tractor is a hunk of iron for 7500 pou ds |

Points need a light touch-up? It seems that every old gasser I buy or go to help with these days doesn't have spark and needs a quick touch with the points file to get good contact, as they oxidize after sitting. Back in the day you used to be able to remove the oxide layer by giving it a rub between the points with a piece of unbleached paper (like a brown paper bag) or dollar bill, but anymore I find a very light stroke with a points file is needed. Also check the carbon centre probe in the dizzy cap and where it contacts the centre of the rotor. Frequently some buildup of crudulence precents good contact, and those carbon pieces and springs can get rusted/brittle and break.

| In 1966 Dad bought a new 190 XT LP. That was a nice tractor. It was hard on distributor caps because of the high compression the spark liked to make a path to another spark plug with less resistance. |
