John Deere 942 Combine Parts

942 parts and accessories

The John Deere 942 combine, produced in the late 1970s and early 1980s, was a popular choice for farmers seeking a reliable and efficient grain harvesting solution. Powered by a robust diesel engine providing ample horsepower, the 942 accommodated a range of header widths to suit various field sizes. Its conventional separator system made it well-regarded for clean grain samples and ease of maintenance.

The John Deere 942 combine harvester was introduced as a successor to earlier John Deere models, aiming to provide improved harvesting performance and operator comfort. Production years spanned from approximately 1978 to 1984. The 942 typically featured a John Deere 6-cylinder diesel engine, producing around 145 horsepower, with a displacement around 466 cubic inches. It used a conventional cylinder and concave system for threshing, relying on a straw walker system for separating grain from the straw. The grain tank capacity was approximately 125 bushels, with an unloading auger speed around 25-30 bushels per minute. Available header widths ranged from 13 to 20 feet. Chopper and spreader options were available to manage residue. The cab offered basic operator comfort with features like air conditioning and a comfortable seat, but was more rudimentary than modern combines. The 942 was especially well-suited for harvesting wheat, soybeans, and other small grains. While not as sophisticated as later models, the 942 provided a good balance of reliability and performance for its time.

Maintenance Tips

Concave Adjustment: Regularly check and adjust the concave clearance according to the crop being harvested. Proper concave settings are crucial for efficient threshing and minimizing grain damage.
Belt and Chain Tension: Inspect all belts and chains for proper tension. Loose belts and chains can slip, causing reduced performance and premature wear. Adjust tensioners as needed.
Sieve and Chaffer Cleaning: Regularly clean the sieves and chaffers to ensure proper airflow and separation. Clogged screens reduce cleaning efficiency and increase grain loss.
Bearing Greasing: Grease all bearings regularly according to the manufacturer's recommendations. Proper lubrication extends bearing life and prevents costly breakdowns.
