Quality of Cut

You want to be proud of the way the job looks whether you are mowing along a road, mowing a pasture, or mowing around your house. The John Deere line of flex-wing cutters has these key features that will ensure you can take pride in a job well done:

  • High blade-tip speed: This allows you to mow faster without sacrificing cut, saving you time and effort, especially when covering large areas.
  • Tall deck height: Ensures even, streak-free material dispersal by allowing optimal airflow.
  • Optional 540 or 1000 RPM PTO speeds available; Offers flexibility to match your mowing and equipment needs.
  • Many blade combinations: Customize your mower to handle different mowing conditions.
