John Deere T660 Combine Parts

T660 parts and accessories

The John Deere T660 combine, produced from approximately 2012 to 2015, offered farmers a powerful and efficient grain harvesting solution. Boasting around 360 engine horsepower and available with header widths up to 40 feet, the T660 featured a robust conventional threshing and separating system. Its reliability and high throughput made it a popular choice for harvesting wheat, soybeans, and other grains.

The John Deere T660 was introduced as part of the T-Series combine lineup, manufactured approximately from 2012 to 2015. Powering the T660 is a John Deere PowerTech 9.0L 6-cylinder diesel engine, delivering approximately 360 horsepower. This engine provides ample power for threshing and separating high volumes of grain. The T660 utilizes a conventional threshing system featuring a high-capacity cylinder and concave. Grain tank capacity is rated at approximately 300 bushels, and the unloading auger achieves a rate of around 3.3 bushels per second (200 bu/min), minimizing downtime during harvest. Available header widths range from 25 to 40 feet, catering to various field sizes and crop types. The T660 offered options for both straw choppers and spreaders to manage residue efficiently. The combine's cab is designed for operator comfort and visibility, featuring advanced controls and monitoring systems. The T660 excels at harvesting small grains like wheat and barley, as well as soybeans and other row crops.

Maintenance Tips

Concave Adjustment: Regularly inspect and adjust concave clearance to ensure proper threshing without excessive grain damage. Refer to the operator's manual for recommended settings based on crop type and conditions.
Belt and Chain Tension: Check belt and chain tension throughout the combine regularly, especially the header drive belt and feeder house chain. Loose belts and chains can cause slippage, reduced performance, and premature wear.
Sieve and Chaffer Cleaning: Clean sieves and chaffers frequently to remove debris and prevent plugging. This ensures optimal cleaning performance and reduces grain loss. Use compressed air or a brush to remove accumulated material.
Bearing Greasing: Follow the recommended greasing schedule in the operator's manual for all bearings. Proper lubrication extends bearing life and prevents costly breakdowns.
