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:

• Clipping pastures encourages grass growth, optimizing on valuable pasture acreage.
• Cutting grass and stocks helps control insects.
• Routine cutting keeps weeds from reseeding.
• It is the most cost efficient way to cut roadsides, parks, cemeteries, airport fields, hydro, gas, and telephone easements, and all other types of open properties.
• Cutting grass waterways encourages root development and helps prevent erosion.
• Knocking down stalks is essential in no-till and minimum-till fields.
• Shredding stalks such as cotton, corn, and milo speeds up decomposition.
• Clearing out brush is easy.
• Use a rotary cutter to control undergrowth and grass in orchards, vineyards, and groves.

John Deere rotary cutters are available in three duty-level categories, three different spindle configurations, four hitch types, and three flex-wing sizes.

• Mid-duty
  • MX models are available in 1.5-m (5-ft), 1.8-m (6-ft), 2.1-m (7-ft), 2.5-m (8-ft), 3.2-m (10-ft), and 4.6-m (15-ft) cut widths.
  • This duty-level category cuts brush up to 50.8 mm (2 in.) in diameter.
• Heavy-duty
  • HX models are available in 3.2-m (10-ft), 4.2-m (14-ft), 4.6-m (15-ft), and 6.1-m (20-ft) cut widths.
  • HX6 is available in 1.8-m (6-ft) and the HX7 is available in 2.1-m (7-ft) cut widths; they cut brush up to 101.6 mm (4 in.) in diameter.
• Commercial-duty
  • CX models are available in 3.2-m (10-ft), 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 101.6mm (4 in.) capacity level more frequently and for longer durations.

Exclusive double-deck in HX6

All the MX, HX, and CX Rotary Cutters have the patented Double-Decker™ design. The smooth
dome-shaped decks provide easy cleaning and water runs off for longer product life. Deck thickness increases as the size and cutter duty level increases.

Gearcase and blade holder shown

The John Deere gearboxes:

1. Large seals
2. Large housing
3. Large output shaft
4. Precision forged bevel gears
5. Large bearings
6. Stump jumper

Re-engineered gearcases and blade holders provide the following:

• More horsepower
• Faster blade-tip speed
• Better performance
• Quieter operation
• Increased durability

Front safety chain shield

Rear safety chain shield

Front and rear safety chain shields are standard equipment. They offer protection yet allow material to pass into the cutting area with minimal obstruction:

• They help deflect thrown material and improve shredding.

Five-year warranty on all flex-wing gearboxes

Five-year warranty on all rotary cutter gearboxes

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.

HX6 and HX7 deliver a clean cut

The fast blade-tip speed ensures clean cutting and fine shredding of material.

• HX6: 13,623 fpm (69.2 m/sec) and 155 mph
• HX7: 16,061 fpm (81.6 m/sec) and 183 mph

A forward tip adjustment allows the cutter to be tilted forward slightly, so most of the cutting occurs in the front while the shredding action occurs toward the rear:

• Improves cutting job
• Reduces horsepower requirements

The tapered rear opening spreads shredded material across entire width of cut:

• Reduces windrowing
• Leaves an even blanket of mulch

Heavy-duty gearcase

The heavy-duty gearcase with non-seize self-adjusting slip-clutch driveline is shown at left.

The gearcase horsepower rating is as follows:

• 150 hp (112 kW) continuous
• 210 hp (157 kW) peak

Cast-metal gearcase features:

• Tapered roller bearings and forged gears for longer life (forged gears are stronger because as the gear is heat-forged into shape, the grain of the metal actually changes to follow the outline of the teeth).
• Output shafts are splined, not just keyed, for extra strength.
• Gearcase is solidly mounted to the frame for a long, trouble-free life.
  • Six mounting bolts (not four) are used.
  • Possibility of flange locknuts fracturing from stress or working loose in tough operating conditions is reduced.
  • Frame metal underneath the gearcase is double thickness for more strength.

The factory preset, four-plate slip clutch protects the driveline:

• Especially valuable when operating in brush
• Preset at the factory and never needs adjusting
• Fully shielded driveline for safety

The HX6 and HX7 gearcases come standard with a five-year warranty.
