John Deere 7300 Combine Parts

7300 parts and accessories

The John Deere 7300 combine, manufactured from 1983 to 1989, quickly became a favorite among farmers due to its reliability and efficient harvesting capabilities. Powered by a robust John Deere diesel engine producing around 175 horsepower, the 7300 offered header widths up to 22 feet, allowing for considerable field coverage. Its conventional separator system provided excellent grain quality, contributing to its widespread adoption.

The John Deere 7300 combine was introduced in 1983 as part of the '00 Series' combines, replacing earlier models and bringing updated technology to the field. Production continued until 1989. Powering the 7300 was a John Deere 6.6L (404 cu in) 6-cylinder diesel engine, delivering approximately 175 horsepower. This engine provided ample power for threshing and propulsion. It uses a conventional threshing system with a 47-inch wide cylinder. The grain tank capacity is around 150 bushels. Unloading auger speeds were typically in the range of 45-50 bushels per minute, allowing for quick unloading into grain carts or trucks. Available header widths ranged from 13 to 22 feet. Options included a straw chopper or spreader for residue management. The cab offered basic operator comfort and controls. The 7300 excelled in harvesting a variety of crops, including wheat, soybeans, and corn, thanks to its adaptable header and threshing system.

Maintenance Tips

Concave Adjustment: Regularly inspect and adjust concave clearance based on the crop being harvested. Proper adjustment minimizes grain damage and maximizes threshing efficiency.
Belt and Chain Tension: Check and maintain proper tension on all belts and chains before and during harvest. Loose belts and chains can lead to slippage, reduced performance, and premature wear.
Sieve and Chaffer Cleaning: Periodically clean the sieves and chaffer to remove debris and ensure proper airflow. This prevents grain loss and maintains separation efficiency.
Bearing Greasing: Grease all lubrication points, including bearings, before each harvest season. Proper lubrication extends bearing life and prevents costly repairs.
