What is the best cutter for your job?

NOTE: Only for single spindle and multi-spindle.


John Deere rotary cutters lead the way with innovative design, superior performance, and proven durability. Valuable features such as the Double-Decker™ design and Max Flow cutting chamber 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 powerful gearboxes, blade holders, and compatibility with a wide range of tractors.


Here are situations when a rotary cutter provides value:

  • Clipping pastures encourages grass growth, optimizing valuable pasture acreage.
  • Cutting grass and stalks 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 such as cotton, corn, or milo speeds up decomposition. This is essential in no-till and minimum-till fields.
  • Clearing out brush.
  • Control undergrowth and grass in orchards, vineyards, and groves.

Decide what model to use based on:

  • The size of the area to mow versus the size of the machine – the bigger the area to mow, the bigger the mower needs to be in order to be efficient during mowing hours. Similarly, the limitation of a small area will guide operators to use a smaller mower.
  • The amount of time and frequency it will be used – for longer hours and more frequency, choose a heavier duty machine.
  • Tractor compatibility – if there is a tractor the operator will be using, look for the tractor compatibility sheet to identify appropriate options.

John Deere rotary cutters are available in two duty-level categories:

  • Mid-duty
    • RC M models are available in 1.5-m (5-ft), 1.8-m (6-ft), 2.1-m (7-ft), 2.5-m (8-ft), and 3.2-m (10-ft).
    • This duty-level category cuts brush up to 50.8 mm (2 in.) in diameter.
  • Heavy-duty
    • RC R models are available in 3.2-m (10-ft) and 4.2-m (14-ft).
    • This duty-level category cuts brush up to 76.2 mm (3 in.) in diameter.
    • RC6R is available in 1.8-m (6-ft) and the RC7R is available in 2.1-m (7-ft) cut widths; they cut brush up to 101.6 mm (4 in.) in diameter.

NOTE: R Series are heavier built to cut at a 101.6 mm (4 in.) capacity level more frequently and for longer durations.

Front and rear safety chain shields are standard

Rear safety chains (RC6M shown) Rear safety chains (RC6M shown)

Front and rear chain shields are standard equipment:

  • Offer protection for the operator yet allow uncut material to pass into the cutting chamber with minimal restriction
Standard suction blades provide additional blade lift

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.


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

  • Up to 88.5 m/sec (17416 fpm)
Five-year limited gearbox warranty provided on every John Deere rotary cutter
Five-year warranty on all flex-wing gearboxes Five-year warranty on all flex-wing gearboxes
Five-year warranty on all rotary cutter gearboxes Five-year warranty on all rotary cutter gearboxes

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, including drivelines, clutches, and many other components.

Good Rotary Cutter

I use the MX6 with a JD 5300 (w/FEL); the perfect complement. I formerly used an MX7 which was oversized (no PTO margin) resulting in slow cutting and tractor wear. With the MX6, I can top the pasture in B/3, and have 20 hp of PTO margin. Dragging at ground level results in very nice finish cut. The archtop geometry with integrated deck stiffeners appears to be an efficient design; more stiffness with less mass. The box volume seems to have more vertical height compared to flat box cutters; I think this reduces box congestion resulting in reduced power consumption; also mulches well. I've gotten into some saplings without any shutter. I compared to others brands; for me, the MX6 was the best value.

Output shaft breaks or bends

Google John Deere MX6 problems before you buy this, a lot of these have bad gearbox's. I bent the output shaft with in 10 hours of use and John Deere wants over $2000.00 for the parts to fix it plus labor, I paid less than $2900.00 for the cutter new. It would be nice if John Deere would step up and stand behind there products.
