Rock Dam Pro for HD Headers (2021 to 2024 Models)

The Rock Dam Pro for HD Headers is not just a rock guard. It is a heavy-duty combine protection system built for the HD header operators who push their equipment hardest, who run in fields where rocks are frequent, dirt volumes are high, and the standard rock dam solution gets tested to its limits every harvest day.

Manufactured by Trueline MFG and available through Leedale Colony on Hutterite Marketplace, the Rock Dam Pro is the upgraded variant of the HD Header Rock Dam, designed specifically for John Deere HD headers from model years 2021, 2022, 2023, and 2024. Where the standard HD Rock Dam handles typical field conditions with ease, the Pro version is built with a heavier, more robust construction to stand up to the most demanding harvesting environments Prairie operators encounter.

Installation follows the same straightforward bolt-on process as the rest of the Trueline MFG Rock Dam lineup. No drilling, no modifications to your header, no specialty tools. The Pro mounts cleanly to your 2021 to 2024 HD header and goes to work immediately, intercepting rocks, dirt, and debris before they reach the feeder house while maintaining smooth, uninterrupted crop flow throughout the day.

Important Compatibility Note: This product fits John Deere HD headers from model years 2021 to 2024 only. The 2025 model year HD header uses a different mounting configuration and requires the dedicated 2025 John Deere HD Rock Dam. Please review the product photos carefully before ordering to confirm this unit is the correct fit for your header. Contact Leedale Colony through the Hutterite Marketplace messaging system if you have any fitment questions before purchasing.

Understanding Your Order:

The Rock Dam Pro for HD Headers is sold as a single unit, per header. This product is confirmed to fit John Deere HD headers from model years 2021 through 2024 only. Buyers running 2025 HD headers should refer to the separate 2025 John Deere HD Rock Dam listing. Orders are fulfilled directly through Leedale Colony. Ordering before or early in harvest season is strongly recommended to secure your unit ahead of peak demand periods.
