Fuel Type:

The Farmall is a row-cropped tractor with three engine variations: the kerosene, gasoline, and the distilled engine. All were four-cylinder C-152 engines.

The introduction of the letter series in the late 1930s was because of the need to create medium-sized tractors that could still achieve a lot. Thus, Farmall H was built by the International Harvesters from the year 1939 till 1953 in Rock Island, Illinois, USA.

The tractor was built as general-purpose machinery to handle a large number of farming activities. It succeeded the Farmall F20 and preceded the Farmall Super H in 1953. It has a sliding gear transmission with 6 gears—5 forward and 1 reverse gear and an open operator cab type.

The 2-wheel drive has a cylinder bore/piston stroke dimension of 88 x 106mm (3.39 in x 4.75 in). It is steered manually and has mechanical brakes. Its fuel tank is a medium-sized 66litres.

Any effectively maintained Farmall H could cultivate over 35 acres of land daily of high row crops. These crops can include sugar beets, maize, buckwheat, potato, or soybeans. The Farmall H is famous as an all-purpose farm tractor that can be used for numerous farm activities. These may include seeding, disking, towing, planting, cultivation, mowing, making hay balls, and even cropping.

History of the Farmall H

Farmall H Tractor Review

The production of the Farmall H began in the year 1939. The company sold over 390,000 of the 2WD row crop tractor, making the most sales of all IH‘s letter tractors. It was styled and designed by the renowned “Father of industrial designs,” Raymond Loewy. Initially, the Farmall H was called McCormick-Deering Farmall H by International Harvester.

It was created within the same time span as the Farmall M tractor—the largest row crop tractor by International Harvester. Throughout the final years of its production, Farmall H was sold as Super H. There wasn’t much distinction between the two, but notably, the Super H had larger engines and larger power.

If you are ready to know more about the Farmall H, read on as we describe the specifications in a table for you.

This medium-sized row-crop tractor has a huge functional advantage compared to its predecessor, the Farmall F20. It has 5 forward gears and delivers at an RPM of over 1650, towering over the Farmall F20’s 4-gear and 1000RPM.

Features of the Farmall H


As we already know, this 2-wheeler can be equipped with any of the three International C-152 engines. Their similarities are much, but there are some differences you shouldn’t miss to outline:

  • The International C-152 Kerosene Engine

This engine was created by the International Harvesters. Its displacement is 152.1 cubic inches (2.5 liters) and 2,492 cm2. Its cylindrical bore is 3.39 inches, and its piston stroke is 4.25 inches. The engine is cooled by liquid cooling, and it cleans its air through oil bathing.

For a medium-sized tractor, Farmall, H has a 6-volt hand-starter electrical system. The compression is 4:5:1, and its RPM rating is 1650. It also has a 24.17hp (18kW) horsepower at the drawbar and 26hp (19.4kW) at the belt.

  • The International C-152 Gasoline Engine

This is a very similar engine to the Kerosene engine. Its displacement, cylinder bore, and stroke are all the same; however, its compression rate is different at 5:9:1. Also, its power rating is 25.50hp (19.0kW) at the drawbar and 27.90hp (20.8kW) at the belt. The coolant capacity and oil capacity are the same for all three engines at 15.6L and 5.7L, respectively.

  • The International C-152 Distillate Engine

The distillate engine also has similarities with the other engines in displacement, cylinder bore, piston stroke, and RPM; the compression is 4:75:1. The distillate engine has a horsepower of 24.34hp (18.1kW) at the belt and 22.65hp (16.89kW) at the drawbar.


The Farmall H is a 2-wheel drive (2-WD) that is manually steered, as we have said before. Its transmission is a sliding gear dry disc clutch that is a bit mechanical in control.

The tractor has 6 gears— 5 forward gears in the firing order of 1-3-4-2. It has a forward speed of 26.3kmh and on reverse 4.4kmh. The capacity for its transmission oil is 22.7L.


The Farmall H tractor was created to be a medium-sized tractor in architecture and in activities. Its tire dimensions are as follows:

  1. Front tiresAg:50-16, 6-16
  2. Rear tiresAg:00-36, 8-38, 9-38, 10-38 or 51×6 (steel)

How Much Does the Farmall H cost?

The Farmall H sold at a price of $2,000 in the year 1939, which is equivalent to $38,111.80 as of today. Though, it’s highly possible to get a fairly used Farmall H in a great condition for an average of $1,000.

It’s also advisable you run a proper check on any tractor you desire to get.


This Farmall H tractor is an 82-year old rugged machinery. With enough horsepower to work adequately on 163-acre farmland while putting manpower to ease. It wouldn’t be a bad consideration. However, there are a couple of factors to consider before acquiring the property, as conditions may vary. If you desire to go an affordable row-crop tractor with sufficient power, then it is a great choice. But if you need a mega tractor for a much larger set of tasks, then you can consider another product.
