Ford New Holland 4100 Tractor Parts
4100 parts and accessories
The Ford New Holland 4100, manufactured from 1965 to 1975, was a popular utility tractor known for its reliability and versatility. Equipped with a robust 3-cylinder engine producing approximately 39 horsepower (depending on the specific model), and boasting around 34 PTO horsepower, the 4100 became a workhorse on farms across the country. Farmers appreciated its compact size and ability to handle a wide range of tasks.
The Ford 4100 was introduced in 1965 as part of the 100 series Ford tractors. It remained in production until 1975, serving as a staple utility tractor for small to medium-sized farms. The tractor was typically powered by either a Ford 158 CID 3-cylinder gasoline engine producing around 39 HP, or a Ford 175 CID 3-cylinder diesel engine also around 39 HP. Both engines were known for their fuel efficiency and durability. The transmission was typically a 6-speed forward, 2-speed reverse gear transmission, providing ample speed options for various farming tasks. The PTO delivered approximately 34 HP at 540 RPM. The hydraulic system had a capacity of around 7.2 GPM, powering implements and loaders. The 3-point hitch was a Category I, providing good lifting capacity for its size. The 4100 found applications in row crop work, hay production, livestock operations, and general tillage. While other tractors in the lineup offered more horsepower or specialized features, the 4100 distinguished itself with its balance of power, economy, and ease of use.

- Engine Oil & Filter: Change the engine oil and filter every 200-250 hours of operation using the recommended oil type and filter specification for optimal engine health.
- Hydraulic System: Inspect hydraulic fluid levels regularly and change the hydraulic filter every 400-500 hours. Use the correct hydraulic fluid type to prevent damage to seals and components.
- Fuel System: Use clean fuel and inspect the fuel filter regularly, replacing it as needed, especially before seasonal storage to prevent fuel degradation and clogging. Drain any water accumulation in the fuel system.
- Seasonal Storage: Before storing the tractor for extended periods, drain the fuel tank (or add a fuel stabilizer), grease all fittings, and disconnect the battery to prevent corrosion and battery drain. Store under cover when possible.
