Description
When you’re cutting hay in tough conditions, every blade matters. A dull or damaged disc knife can leave your grass cut ragged or missed entirely, which means lower quality feed and more time in the field. This left-hand drum knife is built to keep your Krone or Fella mower cutting clean and efficient, so you can get the job done right the first time.
What You’re Getting
- Precision-engineered 11-degree twist that slices through grass cleanly instead of tearing it
- Balanced left-hand rotation that works perfectly with your mower’s drum system
- Durable steel construction that holds its edge through season after season of use
- Direct replacement design—bolts right on with no modifications needed
Built for Real Farm Work
This knife fits Krone and Fella disc mowers that are workhorses in hay operations across the country. Whether you’re cutting alfalfa for dairy cows, making grass hay for beef cattle, or handling mixed forage, these mowers are built to cover ground fast while maintaining cut quality.
Made to Last
The KONDEX steel construction can handle rocks, stumps, and the occasional fence post that somehow gets in your path. The 11-degree twist angle gives you the perfect balance of cutting efficiency and durability, while the precise thickness ensures it spins true even at high speeds.
Good to Know
Make sure you’ve got the right bolt kit—this knife uses RF137 bolts specifically designed for Krone systems. When replacing knives, it’s smart to check the condition of your bolts and nuts too, since a loose knife can damage your drum housing. Always replace knives in pairs to keep your drum balanced.
