John Deere 430 Combine Parts

430 parts and accessories

The John Deere 430 combine, produced from 1977 to 1982, was a popular choice for farmers needing a reliable and efficient machine. With engine options delivering around 105-115 horsepower and available header widths up to 15 feet, the 430 was well-suited for smaller to medium-sized farms. Its conventional separator design provided a dependable harvesting solution for a variety of grain crops.

The John Deere 430 combine was introduced in 1977 and remained in production until 1982. Powering the 430 was either a John Deere 4276D 4-cylinder diesel engine delivering 105 HP (early models) or the John Deere 4276T turbocharged diesel engine producing 115 HP (later models). Both engines had a displacement of 276 cubic inches (4.5 liters). The 430 utilized a conventional cylinder and concave system for threshing, providing effective separation for various crops. It featured a grain tank capacity of approximately 85 bushels and an unloading auger capable of discharging grain at a rate of around 40-50 bushels per minute. Header widths varied but commonly ranged from 13 to 15 feet. Options included a straw chopper or spreader. The cab offered basic operator comfort and controls for adjusting harvesting parameters. The John Deere 430 excelled at harvesting wheat, soybeans, and corn in optimal conditions, establishing a reputation for durability and ease of maintenance.

Maintenance Tips

Concave Adjustment: Regularly inspect and adjust concave clearance based on the crop being harvested to optimize threshing performance and minimize grain damage.
Belt and Chain Tension: Check and maintain proper tension on all belts and chains, especially the header drive, separator drive, and unloading auger drive, to prevent slippage and premature wear.
Sieve and Chaffer Cleaning: Regularly clean the sieves and chaffer to remove debris and ensure proper air flow, maximizing grain cleaning efficiency and reducing losses.
Bearing Greasing: Grease all bearings according to the manufacturer's recommendations, paying close attention to the header, separator, and wheel bearings, to prevent premature failure and extend component life.
