Gleaner R52 Combine Parts

Jump to Parts

The Gleaner R52 combine, produced from 1993-2003, was a workhorse in the fields, powered by a robust engine offering around 250 HP. Known for its transverse rotor design, this combine delivered exceptional grain quality and reduced header losses. Available with header widths up to 30 feet, the R52 earned a reputation among farmers for its reliability and efficient harvesting capabilities, particularly in challenging crop conditions.

Introduced in 1993, the Gleaner R52 replaced earlier models and quickly became a popular choice due to its advanced features for its time. The R52 is powered by a Cummins 8.3L diesel engine, delivering approximately 250 horsepower. Its transverse rotor design offers a unique approach to threshing and separating grain. This design contributes to lower grain loss and higher quality output. The grain tank holds approximately 300 bushels, and the unloading auger empties at a rate of around 2.5 bushels per second (150 bu/min). Header widths available ranged from 20 to 30 feet, accommodating various field sizes and crop types. Options included straw choppers and spreaders for residue management. The cab offered enhanced comfort and controls, including air conditioning and monitoring systems, making long harvest days more manageable. The Gleaner R52 excels at harvesting a wide variety of crops, including wheat, soybeans, corn, and sorghum.

Maintenance Tips

Concave Adjustment: Regularly check and adjust concave clearance according to the crop being harvested to optimize threshing efficiency and minimize grain damage.
Belt and Chain Tension: Inspect and maintain proper tension on all belts and chains. Loose belts or chains can lead to slippage, reduced performance, and premature wear.
Sieve and Chaffer Cleaning: Clean sieves and chaffers frequently to prevent buildup of debris, ensuring proper separation and reducing grain loss.
Bearing Greasing: Grease all bearings regularly according to the manufacturer's recommendations to prevent friction, overheating, and premature failure. Conduct a pre-season inspection and lubrication of all moving components.
