Case IH 300 Tractor Parts

300 parts and accessories

The Case IH 300 tractor, produced from 1955 to 1956, was a workhorse for many farms. It was powered by a 35 horsepower engine and had a PTO horsepower of around 30. Its versatility in row crop and general farm tasks made it a popular choice for farmers seeking a reliable and affordable tractor.

The Case IH 300 was introduced in 1955 as part of the International Harvester (IH) Farmall line, later becoming Case IH. Production lasted until 1956. It was designed as a utility tractor for various agricultural tasks. The engine was a 144ci IH C-144 gasoline engine producing approximately 35 engine horsepower. Some models were later equipped with diesel engines. The transmission was typically a 4-speed gear transmission, providing adequate speed ranges for field work. The PTO delivered around 30 horsepower, suitable for operating implements like rotary cutters and small balers. Hydraulics offered a flow rate of about 6.5 GPM. The 3-point hitch was Category I, allowing for the use of a range of implements. Common applications included row crop work, hay production, and general farm maintenance. The 300 differed from larger IH models by its smaller size, lower horsepower, and simpler design, making it ideal for smaller farms or secondary tasks on larger operations. The 300 set itself apart in the compact tractor segment.
