Rock Dam for John Deere D Series Headers

The John Deere D Series header is one of the most established and widely used platforms across Prairie grain operations. For every season those headers have been running, rocks have been a threat to the combines behind them. The Rock Dam for John Deere D Series Headers is a purpose-built solution that puts that threat to rest with a simple, no-drill bolt-on installation that any farm crew can handle.

Manufactured by Trueline MFG and available through Leedale Colony on Hutterite Marketplace, this rock guard is designed to fit all D Series header configurations. It mounts directly to your header, requires no drilling or modification to your equipment, and is engineered to intercept rocks and field debris before they reach your combine’s feeder house, while maintaining smooth, unrestricted crop feeding throughout the day.

The D Series platform has served countless Prairie operations through thousands of harvest hours. Protecting that equipment from rock damage is not a complicated decision, and the Rock Dam makes the solution just as straightforward as the problem demands. Bolt it on, run your header, and harvest with confidence.

At $400 CAD, the Rock Dam for D Series headers is the most accessible unit in the Trueline MFG Rock Dam lineup, giving D Series operators a clean, practical entry point into combine rock protection without a significant upfront cost relative to the repair bills it prevents.
