John Deere 3641 Tractor Parts

The John Deere 3641 tractor was manufactured between 1980 and 1983, filling a need for a mid-size utility tractor capable of handling various farm chores. The engine was a Yanmar 3T90J diesel, a 1.6L (97.4 cu in) three-cylinder engine producing approximately 41 horsepower. The transmission was a gear-type with 8 forward and 2 reverse speeds, providing a good range for different applications. The PTO delivered around 35 horsepower at 540 RPM, suitable for operating implements like mowers, tillers, and balers. The hydraulic system had a capacity of approximately 7.9 gallons per minute, powering two remote outlets. It features a category I 3-point hitch, which can lift approximately 2,100 lbs. Farmers commonly used the 3641 for hay production, livestock operations, light tillage, and general utility work. Compared to smaller models, the 3641 offered more power and hydraulic capacity, while being more compact and fuel-efficient than larger row-crop tractors.
