One rock through the feeder house can cost you thousands in drum repairs and stall your harvest for days. If you farm rocky ground in Saskatchewan or Alberta, you already know the sound — that sickening bang followed by silence.
The fix more prairie farmers are bolting on is the Rock Dam Pro: a rock guard that mounts to your MacDon or John Deere header and intercepts stones before they reach the combine.
How rocks damage combines
Rocks lifted by the cutterbar travel straight into the feeder house, where they hammer the drums, damage the stone trap, and can plug or break internal components. A single bad stone in canola or pulse harvest can end your day.
How the Rock Dam Pro stops them
It mounts directly in front of the center canvas using existing bolts. Welded fins catch lifted rocks and vibrate them off the header, while dirt passes through and crop feeds normally. No drilling on most headers, under an hour to install.
What it costs vs. what it saves
Feeder house repairs run into the thousands, plus lost harvest days. The Rock Dam Pro costs a fraction of one repair bill — cheap insurance for rocky quarters.
