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.
Dual blades are effective for increased shredding of crop residue.
The dual blades consist of a 1.3-cm x 10.2-cm (1/2-in. x 4-in.) lower suction blade and a 1.3-cm x 7.6-cm (1/2-in. x 3-in.) upper suction blade.
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.
The lift-type versions fit tractors with Category 2, 3, or 3N 3-point hitches (with or without Quick Hitch).
NOTE: The lift-type versions require a larger tractor than other versions. For HX10 Lift-Type Rotary Cutters, the minimum-size tractor recommended is a 6020 Series or equivalent. For HX14 Lift-Type Rotary Cutters, the minimum-size tractor recommended is a 7720 or equivalent. Refer to the tractor's operator's manual for ballasting instructions. The pull-type versions of the HX10 Multi-Spindle Rotary Cutter require a tractor with a minimum of 50 power take-off (PTO) hp. The HX14 pull-type versions require a tractor with a minimum of 60 PTO hp. Note that the type and volume of material being cut affect horsepower requirements.
Parallel lift linkage helps keep the cutter level through all height adjustments. Cylinders are John Deere manufactured, meaning more reliability and durability.
Gearcases are John Deere designed for reliability and dependability:
Heavy-duty, tapered roller bearings and precision gears help ensure long life.
Output shafts are splined, not just keyed, for extra strength and durability.
Gearcases mount on heavy-duty bowl supports, which are continuously welded to the top and bottom decks. These bowls provide a lifelong base of support for the gearcase/blade holder mechanism.
The HX14 comes standard with five year warranty.
The John Deere gearboxes:
Re-engineered gearcases and blade holders provide the following:
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.
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.
