Description
When you’re out cutting hay or managing pastures, you need sharp, reliable disc mower knives that stay in the cut. A dull or damaged drum knife means ragged cuts, missed grass, and more work for your tractor. This left-hand disc mower drum knife with its 18-degree twist design gives you the clean cutting action your AGCO Hesston or New Holland disc mower was designed to deliver.
What You’re Getting
- Precise 18-degree twist angle engineered for optimal cutting performance on rotating drums
- Proper bevel orientation – down on the front side of rotation, up on the backside for consistent cutting action
- Durable KONDEX construction that holds its edge through long cutting sessions
- Standard 0.728-inch bolt hole size for easy installation with existing hardware
- Pairs with right-hand knife 798-RM575 for complete drum setup
Built for Real Farm Work
This knife fits AGCO Hesston, Case IH, and New Holland disc mowers – the workhorses you’ll find cutting hay fields, maintaining pastures, and cleaning up roadside ditches across farm country. These machines see everything from thick alfalfa stands to tough roadside grass, and they need knives that can handle the variety.
Made to Last
Farm cutting equipment takes a beating from rocks, dirt, and constant use. This KONDEX knife is built to maintain its sharp edge and proper twist angle through season after season of cutting. The steel construction resists chipping and holds up to the vibration and impact that comes with disc mowing.
Installation Notes
Use bolt kit RF11964K for proper installation – having the right hardware ensures your knife stays secure during operation. Always replace knives in pairs to maintain proper balance on your cutting drums, and check that the twist direction matches your drum rotation for best results.
