International Harvester 544 Overview
The International Harvester 544 was built from 1968 through 1973 with both four-cylinder gasoline and diesel engine choices. The listed diesel is the 238.6 cu in (3.9 L) D-239, while the gasoline version uses the 200.3 cu in (3.3 L) C-200. Both are listed at 2,400 rpm, but engine, fuel capacity, cooling capacity, and test information need to stay matched to the tractor in front of you.
Published configurations include a five-speed gear drive, a 10-speed Torque Amplifier version, hydrostatic drive, and a five-speed shuttle. The 544 is listed with independent 540/1000 PTO equipment, a Category II rear hitch, and 6 gpm pump flow with 12 gpm total hydraulic flow. Match the installed transmission and engine before relying on a capacity, adjustment, or parts detail.
There are three official Nebraska records for Farmall 544 configurations: diesel and gasoline tests dated 1968, plus a hydrostatic-diesel test dated 1969. They are linked as individual records rather than blended into one generic horsepower number. The reviewed IH-O-544 preview and the operator, service, and parts-manual listings give owners clearer routes to the right literature.
International Harvester 544 Quick Answers
- What engines were offered in the IH 544?The listed engines are the International Harvester D-239 four-cylinder diesel at 238.6 cu in (3.9 L) and the C-200 four-cylinder gasoline engine at 200.3 cu in (3.3 L). Both are listed at 2,400 rpm.
- How much horsepower does an IH 544 have?Published claimed ratings are 52 PTO hp and 45.4 drawbar hp. Three separate Nebraska records exist for Farmall 544 diesel, gasoline, and hydrostatic-diesel configurations, so a tested value must be matched to the exact version.
- What transmissions were offered?The published choices are five-speed gear drive, 10-speed Torque Amplifier, hydrostatic drive, and a five-speed shuttle. Identify the installed version before using gear-count, clutch, or parts information.
- What PTO does an IH 544 use?The 544 is listed with an independent rear PTO and 540/1000 PTO speeds. Confirm the shaft and equipment fitted to an individual tractor before matching an implement.
- What is the IH 544 engine oil capacity?The listed engine oil capacity is 7 quarts (6.6 L) for both published engine variants. Capacity alone does not establish the correct oil grade or fill procedure.
- Where are IH 544 serial numbers located?The serial-number plate is listed on the right side of the tractor at the clutch housing. Published year-start numbers run from 10250 for 1968 to 17341 for 1973.
- Which Nebraska tests cover a Farmall 544?The University of Nebraska archive lists Test 983 for a Farmall 544 diesel and Test 984 for a Farmall 544 gasoline tractor, both dated 1968, plus Test 1029 for a Farmall 544 hydrostatic diesel dated 1969. These are separate configurations.
- Which manuals are available for the IH 544?The reviewed IH-O-544 operator-manual preview identifies publication 1084061R1. Separate commercial listings identify a 176-page operator manual, a 304-page multi-model service manual, and a 544 parts-catalog reproduction.
Engine and Power
The 544 has separately listed D-239 diesel and C-200 gasoline four-cylinder engines. Both are shown at 2,400 rpm, but their displacement, compression, fuel capacity, and cooling capacity differ. Keep the engine type with the tractor when using a specification or manual.

Manufacture years
Transmission
The published 544 configurations include five-speed gear drive, 10-speed Torque Amplifier, hydrostatic drive, and five-speed shuttle versions. The 1969 Nebraska record is specifically a Farmall 544 Hydrostatic Diesel, so it should not be used as a general gear-drive result.

PTO and Hitch
The model is listed with independent rear PTO equipment and 540/1000 speeds. PTO and transmission details should be checked on the individual tractor before selecting an implement or ordering configuration-sensitive parts.

Hydraulics
Published hydraulic figures are 6 gpm pump flow and 12 gpm total flow, with a Category II rear hitch. Those figures are useful for a baseline comparison, while installed remotes, equipment, and condition still matter in use.

Fluids, Battery, and Service Facts
The listed crankcase capacity is 7 qt (6.6 L) for either engine. Fuel capacity is listed as 15 gal for diesel and 23 gal for gasoline; coolant is listed as 15 qt for diesel and 14 qt for gasoline. Use the complete matching operator manual for fluid grades and procedures.
Configuration-specific values are split out where the same model has documented differences by engine, transmission, or equipment.
Fuel tank

Tires and Dimensions
The listed agricultural tire sizes are 6.00-16 front and 14.9-28 rear, with a 73-inch wheelbase. Front axle, wheel, and tire choices can vary by configuration, so use the actual tractor for final fitment.

Serial Number Lookup
The serial plate is listed on the right side of the clutch housing. The published year-start sequence is 10250 (1968), 12699 (1969), 14589 (1970), 16018 (1971), 16838 (1972), and 17341 (1973). It is the starting point for matching literature and parts.

Manuals, Parts, and Nebraska Tests
The IH-O-544 PDF is a reviewed seven-page commercial preview. It identifies the 544 operator manual as publication 1084061R1 and visibly includes the cover, terminology, a diesel gear-drive view, hydrostatic-filter material, and index pages. It is not the full operator manual.
The University of Nebraska archive keeps separate Farmall 544 records: Test 983 diesel and Test 984 gasoline, both dated September 1968, and Test 1029 hydrostatic diesel, dated November 1969. Use the exact record and its configuration when comparing tested performance.
Commercial listings also point to a 176-page operator manual, a 304-page multi-model service manual, and a 544 parts-catalog reproduction. They are literature-access references; a full serial-matched publication remains necessary for a repair setting, part number, or procedure.

Parts Checks Before Ordering
Start with the serial plate and engine type, then identify the five-speed, Torque Amplifier, hydrostatic, or shuttle transmission. PTO equipment, front axle, and tire configuration can also affect a parts match.
The parts-catalog listing is a useful starting point, while the multi-model service-manual listing covers 544 gasoline and diesel machines. Neither listing should be treated as a substitute for a serial-matched catalog or complete manual when choosing an individual part or repair procedure.

Accuracy Note
Tractor specifications can vary by year, region, factory configuration, installed equipment, and later repairs. Match serial range, engine, transmission, PTO setup, and model code before ordering parts or doing service work.
