Combine Grain Tank Extensions & Hopper Toppers

A diagram describing combine grain tank extensions

Demco combine grain tank extensions and tip-ups are an excellent addition to any combine, and many of our dealers commonly call them the best in the industry. Great looking, durable and efficient, these Demco factory replacements add more capacity to your John Deere, Case IH or New Holland combine, and they're as economical as they are useful.

Replacing the factory extension for added bushel capacity and lower clearance of the combine, Demco grain tank extensions provide superior fit, finish and quality, so you don't have to risk your combine's safety or looks just because you want increased harvest efficiency. On the other hand, our combine hopper toppers or grain tank tip-ups are an inexpensive way to add capacity to a factory extension.
