Rubber element connecting drivelines help absorb the sudden stress of impact loads. Chain couplers are used to maintain the driveline alignment.
A non-seize slip clutch used between the primary gearcase and power take-off (PTO) helps protect the driveline. Slip clutches feature a spring-compression adjustment used to ensure clutches are not seized.
Lift-type and semi-mount models feature an ASAE Category 4 driveline for added durability.
The pull-type model uses an equal-angle driveline for smoother, rattle-free turns.
A lightweight driveline with a lock-slide collar makes it fast and easy to attach.
The driveline provides long lubrication periods; a 50-hour cycle reduces maintenance time, making the cutting operation more efficient.
The patented Double-Decker design provides strength and superior cutting performance while reducing top deck rust. Two welded decks, each 3-mm (1/8-in.) thick, form the upper and lower surfaces of the rotary cutter frame.
Internal stiffeners are sandwiched between the two decks, providing superior strength and rigidity.
The top deck is domed. Water, grass, and crop debris tend to roll off the deck, reducing water buildup and deck rust. The domed shape and smooth profile of the top deck also make the deck easier to clean when trash does build up in adverse conditions.
The bottom deck is the main defense against rocks and field debris. Therefore, the top deck is continuously protected from impacts and tends to retain its smooth form.
Because the stiffeners are located between the two decks, the underside of the bottom deck is perfectly smooth; there are no structural frame members to interrupt airflow. This improves both cutting performance and distribution.
Standard material flow deflectors help channel the cut material, further improving material distribution.
John Deere is so confident in the reliability of the gearbox, the warranty has been extended. John Deere rotary cutters come with a 5-year limited gearbox warranty.
John Deere rotary cutters lead the way with innovative design, superior performance, and proven durability. Valuable features are included such as the Double-Decker™ design and Max Flow cutting chamber, which prevent water and debris from accumulating on the smooth, dome-shaped top deck while the flat bottom deck absorbs the punishment from rocks and stumps.
The top deck stays smooth - no dents, no dings, no holes. The internal supports sandwiched between the top and bottom decks are key to the smooth and structure-free Max Flow cutting chamber, while at the same time provide added strength and durability.
To help promote safe operation, John Deere rotary cutters are equipped with front and rear safety-chain shields. John Deere rotary cutters continue to advance in value with larger, more powerful gearboxes, redesigned blade holders, and updated constant-velocity (CV) drivelines (special to the flex-wing models).
Here are situations when a rotary cutter is needed:
John Deere rotary cutters are available in three duty-level categories, three different spindle configurations, four hitch types, and three flex-wing sizes.
NOTE: CX models are heavier built to cut at a 101.6mm (4 in.) capacity level more frequently and for longer durations.
Front and rear chain shields are standard equipment:
Round-pan blade holders (stump jumpers) are provided as standard equipment on most John Deere rotary cutter models. Stump jumpers increase the drivetrain reliability by providing protection against impacts such as stumps, rocks, and other obstacles.
