Description
When your planter’s jackshaft isn’t turning smoothly, you’ll notice it right away—uneven seed spacing, missed hills, or that grinding noise that means trouble. A worn or stretched drive chain is usually the culprit, especially on planters that have covered a lot of ground. This 66-link precut chain gets your jackshaft system back to transferring power the way it should, keeping your seed meters running at the right speed for consistent planting.
What You’re Getting
- Precut to the exact 66-link length—no measuring or cutting needed
- Quality steel construction that handles the stress of constant flexing and loading
- Includes connecting link for easy installation
- Direct replacement for John Deere AA38451
Built for Real Farm Work
This chain is designed for the jackshaft drive systems on John Deere 1770 planters—machines that are workhorses in corn and soybean country. The jackshaft transfers power from your ground drive wheels to the individual row units, and when that chain starts wearing or stretching, your whole planting operation suffers.
Made to Last
Planter drive chains take a beating from dirt, moisture, and the constant flexing that comes with covering acres day after day. This chain’s built with quality materials that resist stretching and wear, keeping your planter running smoothly through long planting seasons when time is everything.
Good to Know
The precut design saves you time—just remove the old chain and install the new one. While you’ve got the drive housing apart, it’s a good time to clean out any dirt buildup and check your sprockets for wear. Proper chain tension is critical for smooth operation, so follow your manual’s specs when you’re putting everything back together.
