When your combine starts leaving ragged stubble or you’re getting uneven cuts in your crop, the problem often traces back to a worn knife head that’s not making clean cuts anymore. This critical component at the end of your sickle assembly does all the heavy lifting, guiding sections through tough crop stems and keeping everything aligned for smooth operation. A fresh knife head gets you back to making clean, efficient cuts that leave proper stubble height and keep your header running like it should.
What You’re Getting
- Precision-built replacement that matches OEM specifications and fit
- Hardened steel construction designed to handle continuous cutting action
- Smooth mounting surface that guides sickle sections without binding
- Direct bolt-on replacement that saves downtime during busy harvest season
Built for Real Farm Work
This knife head is engineered for John Deere’s popular 600 and 700 series rigid draper headers found on combines throughout grain country. Whether you’re cutting wheat, soybeans, or other small grains, these headers see some of the toughest conditions during harvest – rocks, dirt, tough stems, and marathon days that put serious stress on cutting components.
Made to Last
Harvest doesn’t wait, and neither should you when it comes to knife head replacement. This part uses heat-treated steel that holds its edge and mounting points through thousands of acres. The AgSmart manufacturing meets the demanding tolerances needed for smooth sickle operation and reliable performance when every day of good weather counts.
Good to Know
Replacing a knife head is straightforward but requires attention to proper alignment with your sickle sections. Make sure the header is completely shut down and locked out before starting work. Clean the mounting area thoroughly and check that sickle sections slide smoothly before reassembly. It’s worth inspecting your entire sickle while you’ve got things apart – catching worn sections early prevents costly downtime later.
