When you’re dealing with chain-driven systems on your tractor or implement, keeping that chain properly tensioned and guided is critical. This idler sprocket does the important job of guiding and tensioning 50 chain systems found on planters, drills, and other farm equipment. It’s the kind of part that keeps everything running smooth and prevents costly breakdowns when you’re in the middle of fieldwork.
What You’re Getting
- Perfect fit for 50 roller chain with precise 13-tooth engagement that keeps the chain tracking properly
- Standard 5/8-inch bore that mounts on most common shaft sizes without modifications
- Smooth rotation that reduces chain wear and extends the life of your drive system
- Durable construction built to handle the vibration and stress of field conditions
Built for Real Farm Work
This size idler sprocket is commonly used on planting equipment like John Deere 1700 and 7000 series planters, as well as various drill models. The 50 chain size is popular in seed delivery systems, drive mechanisms, and other applications where you need reliable power transmission without the bulk of heavier chains. Whether you’re planting corn, beans, or small grains, this sprocket keeps the chain systems working like they should.
Made to Last
Farm equipment sprockets take a beating from dust, moisture, and constant use. This idler is machined to proper tolerances and built with quality steel that won’t wear out prematurely. The 13-tooth design provides good chain engagement while still being compact enough for tight spaces in machinery.
Good to Know
Installation is straightforward—just slide it onto your 5/8-inch shaft and secure it in position. Make sure to check your chain tension after installing any new idler sprocket. A good rule of thumb is about 1/2 to 3/4 inch of deflection when you press on the chain midway between sprockets.
