Ford New Holland 851 Tractor Parts

851 parts and accessories

The Ford New Holland 851 tractor, produced from 1957 to 1962, was a popular choice for farmers needing a reliable and versatile machine. Powered by a gasoline engine producing around 55 horsepower, its robust design and live PTO made it well-suited for various agricultural tasks. The 851's ease of operation and relatively low maintenance contributed to its widespread adoption across American farms.

The Ford 851 tractor was part of the Hundred Series introduced by Ford in the mid-1950s. It followed the earlier 800 series, bringing improved features and a more modern design. The 851 was manufactured between 1957 and 1962. The engine powering the 851 was typically a 172 cubic inch Ford inline 4-cylinder gasoline engine producing around 55 horsepower. A diesel variant was not available. The transmission was a 4-speed manual gearbox, providing adequate speed ranges for most farming operations. The 851 featured a live 540 RPM PTO, a significant advantage for operating implements like mowers, balers, and rotary cutters. The hydraulic system had a capacity of around 5 GPM, powering the 3-point hitch and any remote hydraulic cylinders. The 3-point hitch was a Category I type, suitable for many implements of the time. Common applications for the 851 included row crop cultivation, haying operations, livestock feeding, and light tillage work. Compared to the smaller 600 and 700 series, the 851 offered more power and PTO functionality, making it more capable for demanding tasks. The Select-O-Speed transmission was also an available option, adding to its versatility.

Maintenance Tips

Change the engine oil and filter every 100-150 hours of operation using a quality oil and filter. This helps maintain optimal engine performance and longevity.
Inspect and maintain the hydraulic system regularly. Check for leaks, ensure proper fluid levels, and replace the hydraulic filter per the manufacturer's recommendations.
Before storing the tractor for the off-season, drain the fuel tank and carburetor to prevent gum and varnish buildup. Add fuel stabilizer to the fuel system if it cannot be completely drained.
Regularly inspect and clean the air filter to ensure proper airflow to the engine. A clogged air filter can significantly reduce engine performance and fuel efficiency.
