John Deere flex-wing rotary cutters lead the way with innovative design, superior durability, and proven performance. Valuable features are included such as a dome-shaped smooth deck, which prevent water and debris from accumulating on the top of the machine and makes it easy to clean up.
Built with a superior structural design that will satisfy different applications and segment desires, the single deck on the flex-wing cutters adds volume on the cutting chamber, allowing the machine to process more material and translating into an improvement in cut quality. The cutting chamber design allows the material to flow through the area and be discharged evenly throughout the width of the machine.
To help promote safe operation, John Deere rotary cutters are equipped with front and rear safety-chain shields and lighting kits to comply with U.S. regulations. John Deere rotary cutters continue to advance in value with larger, more powerful gearboxes, redesigned blade options, and updated constant-velocity (CV) drivelines.
Here are situations when a rotary cutter provides value:
Decide what model to use based on:
John Deere flex-wing rotary cutters are available in three duty-level categories and four width sizes.
John Deere flex-wing rotary cutters are equipped with chains and lights as standard in all models.
Chain shields offer protection to the operator and the area surrounding the cutter, yet allows uncut material to pass into the cutting chamber with minimal restriction.
Lights are required for U.S. regulations on implements wider than 3.05 m (10 ft). All cutters come standard from the factory with lights.
Always use the transport lock on the wings and back axle while transporting or moving the machine.
John Deere is so confident in the reliability of the gearbox that rotary cutters come with a 5-year limited gearbox warranty.
There is also 1-year warranty on the complete machine, as well as drivelines and other components.
John Deere flex-wing rotary cutters are equipped with a single dome deck to allow material debris and water to be easily removed from the top of the machine.
R-spec machines come standard with these features that will reduce overall maintenance time.
There is no need for greasing, as the machine includes internal pre-greased bushings and sealed hinges.
There are no falling caps, as they are sealed for no greasing.
This requires minimal maintenance; operators only need to check that bolts are tightened every 40 hours.
