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 CX Series Rotary Cutters are commercial-duty. CX models are available in 4.6-m (15-ft) and 6.1-m (20 ft) cut widths; they cut brush 101.6 mm (4 in.) in diameter.
NOTE: CX models are heavier built to cut at a 101.6 mm (4 in.) capacity level more frequently and for longer durations.
The patented Double-Decker design improves strength and cutting performance while reducing top deck rust. Two welded decks include a 3-mm (11-gauge, 0.118-in.) to 3.5-mm (10-gauge, 0.138-in.) thick upper deck, depending on the model, and a 3-mm (11-gauge, 0.118-in.) to 4.5-mm (7-gauge, 0.177-in.) thick lower deck, depending on the model.
Internal stiffeners are sandwiched between the decks to add extra strength and rigidity.
The Double-Decker design also provides a sturdy base to support the gearcases. Gearcases need this sturdy base to resist the bending loads imposed upon them when blades contact immovable objects or the ground.
The bottom deck is the main defense against rocks and field debris, to help protect the top deck from impacts so it will retain its smooth form.
The John Deere gearboxes:
Re-engineered gearcases and blade holders provide the following:
Suction blades provide additional lift action for picking up downed material. The blades are 1.3 cm x 10.2 cm (0.5 in. x 4 in.) in size and heat-treated for long wear life.
A fast blade-tip speed (up to 16889 fpm) ensures clean cutting and fine shredding of material.
Flat blades are effective for any materials not downed and require suction for lifting.
Flat blades require less horsepower and have a cutting edge on both sides. Only available with double-blade system.
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.
