Built for Real Farm Work
This chain fits planter drive systems that use #40 roller chain with 109 links. Whether you’re running corn, soybeans, or other row crops, the precise link count ensures proper timing between your seed meter, drive wheels, and other planter components. It’s the exact replacement length for systems that came with this configuration from the factory.
Made to Last
Diamond chains are built to handle the dirt, moisture, and constant flexing that comes with field work. The rollers are heat-treated for wear resistance, and the rivets hold tight even when the chain picks up debris or gets a little sideways tension from worn sprockets.
Good to Know
Count your old chain’s links before ordering to make sure 109 is the right length for your setup. The connecting link makes installation straightforward—you don’t need special tools to join the ends. A little chain lube on the pins and rollers before you install it will help everything run smoother from day one.
