When your flail mower isn’t cutting like it should, worn or dull side knives are usually the culprit. These sideslicer knives do the heavy lifting when you’re chopping up brush, thick grass, or cleaning up fence rows. A sharp set of side knives makes all the difference between a clean cut and leaving behind stringy, half-cut material that looks unprofessional.

Built for Real Farm Work
This knife works on John Deere flail mowers where you’re tackling everything from roadside maintenance to pasture brush hogging. Whether you’re cleaning up after cattle, maintaining fence lines, or keeping ditches clear, these side knives handle the tough cutting jobs that regular blades can’t touch.
Made to Last
Farm equipment takes a beating, and flail mower knives see some of the worst conditions. This blade is built tough enough to slice through saplings, brambles, and thick grass without dulling quickly. The steel construction holds its edge well and won’t crack or chip when you hit the occasional rock.
Good to Know
Installation is straightforward with basic hand tools—just make sure the mower is completely stopped and the PTO is disengaged before you start. It’s a good idea to replace all the worn knives at once rather than doing them one at a time. Keep a few spare knives on hand since hitting buried fence posts or rocks can damage a blade without warning.
