Description
When your planter’s insecticide or herbicide pump starts missing application rates or stops completely, it’s often the drive chain that’s the culprit. This 109-link precut chain keeps your chemical application system running smoothly, ensuring you get the coverage you need for a successful crop. No more guessing about chain length or dealing with oversized chains that need cutting.
What You’re Getting
- Pre-cut to exactly 109 links with one connector included—saves you time and eliminates cutting
- Heavy-duty construction designed to handle the constant operation of chemical pumps
- Direct replacement for worn or broken chains on insecticide and herbicide drive systems
- Quality materials that resist stretching and wear from pump operation
Built for Real Farm Work
This chain fits the chemical application systems on John Deere 7000 and 7100 series planters—machines that have planted millions of acres across the corn belt. Whether you’re applying starter fertilizer, insecticide for rootworm control, or herbicide for early weed suppression, this chain keeps your application system turning at the right speed for accurate rates.
Made to Last
Chemical application pumps run continuously during planting season, which means this chain sees a lot of action. The AgSmart construction holds up to the constant cycling and the agricultural environment, so you can count on consistent chemical application from first row to last.
Installation Notes
Installation is straightforward—just remove the old chain and install this replacement using the included connector link. Check your pump timing after installation to make sure everything’s synchronized properly. A little chain lube on the sprockets helps everything run smoother and extends chain life.
