Ford New Holland TR70 Combine Parts

TR70 parts and accessories

The Ford New Holland TR70, produced from the late 1970s to the mid-1980s, was a popular combine among farmers due to its reliable performance and innovative design for its time. Powered by a robust diesel engine, typically around 155 horsepower, it could handle a variety of header widths, adapting to different field conditions. The TR70 utilized a rotary separation system, offering improved grain separation efficiency compared to traditional conventional combines.

The Ford New Holland TR70 was introduced as part of the Twin Rotor series, marking a significant advancement in combine technology. Production spanned from approximately 1979 to 1984. It was generally equipped with a Ford 6.6L 401 CID inline 6-cylinder diesel engine producing around 155 horsepower. The heart of the TR70 was its twin longitudinal rotor system, designed for more efficient grain separation and reduced grain loss compared to conventional cylinder combines. This system featured two rotors that gently rubbed the grain out, minimizing damage. The grain tank capacity was approximately 200 bushels, and it boasted an unloading auger capable of emptying the tank at a rate of around 50-60 bushels per minute. Available header widths ranged from 13 feet to 20 feet, catering to different field sizes and crop types. Chopper and spreader options were available to manage residue effectively. The cab, while not as advanced as modern combines, provided a reasonable level of comfort and visibility. The TR70 was well-suited for harvesting wheat, soybeans, corn, and other small grains.

Maintenance Tips

Concave Adjustment: Regularly check and adjust concave clearance according to the crop being harvested. Proper adjustment minimizes grain damage and loss.
Belt and Chain Tension: Inspect all belts and chains for proper tension and wear. Loose or worn belts and chains can lead to reduced performance and component failure.
Sieve and Chaffer Cleaning: Clean the sieves and chaffers regularly to ensure proper airflow and separation. Clogged sieves can result in grain loss over the back.
Bearing Greasing: Grease all bearings according to the manufacturer's recommendations. Proper lubrication prevents premature bearing failure and extends the life of the combine.
