Built for Real Hay Work
This knife fits John Deere mower conditioners that do the heavy lifting on dairy farms and hay operations. The 1209 and 1219 series mowers are workhorses designed for cutting everything from first-crop alfalfa to mixed grass hay, and this knife is engineered to keep up with that demanding work.
Made to Last
The riveted construction holds each section securely, even when you hit rocks or stumps that would loosen bolted sections. The fine serrated edge design cuts cleanly and conditions the crop as it cuts, helping you get better dry-down in the field.
Good to Know
Installation is straightforward—just remove the old knife and bolt this one in its place. The needle bearing head comes ready to install, and the 36 sections give you plenty of cutting edge to work with. Keep a few spare sections handy for field repairs when you inevitably find that hidden fence post.
