The Farmall H was a row-crop tractor that was produced from 1939-1953. The H was a fairly successful tractor, having over 390,000 sold. There were three different International Harvester engines used in the Farmall H: gasoline, distillate, and kerosene. They were all liquid-cooled four-cylinders with a bore/stroke of 3.375 x 4.25 inches and a displacement of 152.1 cubic inches. In fact, the only difference came in the compression ratio. The gasoline-ran H had a ratio of 5.9:1, the distillate-ran H had a ratio of 4.75:1, and the kerosene-ran H had a ratio of 4.5:1.
The Farmall H had a sliding gear transmission with five forward gears and one reverse. In a Nebraska Tractor Test on the gasoline-ran Farmall H in October 1939, it produced a max belt power of 26.20hp, and a max drawbar power of 24.17hp. Max belt fuel use was 2.3 gallons/hour. When the distillate-ran H was tested in November 1939, it had a max belt power of 23.3hp and a max drawbar power of 21.4hp.
The H had a typical red Farmall paint job. It had a wheelbase of 88.33 inches and weighed 3,875 pounds. The serial number was located on the left side of the transmission housing, and corresponds with the production year as follows:
1939: 501-10652
1940: 10653-52386
1941: 52387-93236

Hello,
I’m kind of throwing out a long shot but I am trying to locate a 1954 Farmall H Serial # 21342. My Grandpa had bought it new in 1955 and sold to a guy who was going to restore it back in the late 80’s or early 90’s when he sold his farm. I just bought my other grandpa’s 1944 John Deere B and it got me wondering where this Farmall might be. Is there any chance anyone might be able to help me locate it? Call @ 1-763-494-1940

I recently received a job of taking down an old barn inside I found what I think is a 1938 farmall tractor. I do not have the time or money to restore it for it has sat for at least 40 years. If anyone is interested please send me an email.

@Dean, you would need to find and email or call the owner of the photo and ask for their permission. If you click on the image, it will take you to their photobucket account.

I grew up on H tractors. My Dad had 3 of them. He still has 1. They are excellent tractors, never had a problem. I wish I had a brand new one.

If I split a 1941 Farmall H and a 1949 Farmall H, will the 49 rear end match up to the 1941 or is the pilot bearing a different size?

I also have a Farmall H stuck in gear. Shifter feels like fork broke or came out of position. Thank you for any help.

I am looking for Farmall H to fix & ride it cross country for pancreatic cancer awareness. My mother in law suffered from this horrible disease for 8 months. Any assistance getting rolling across the USA will be greatly appreciated. Thank you!! The milk man.

Barbara the hydraulic system on a H uses the same oil the motor uses, the owners manual says 30 weight NON detergent motor oil. Odds are the motor has b33n switched to detergent oil which is fine I wouldn’t suggest putting it in the lift all as it could break loose some sludge and plug up the pump
