MX15 Mower

15' John Deere Brush Hog Mower (3 Point) Medium-Duty Rotary Cutter

  • Constant-velocity (CV) driveline
  • Wings flex to follow any terrain
  • Front and rear safety chains
  • Standard lift and fold hydraulics


MX15 Rigid Axles

MX15 Rigid Axles Detail

The MX15 is equipped with four rigid axle assemblies. The severe-duty agricultural tires that are teamed up to the axle assemblies provide a smooth ride for the terrain type and duty level for which the MX15 is designed.

Gearcase with Oil-level Dipstick (A)

Oil-level Dipstick detail

Gearcases are provided with oil-level dipsticks.

Spring-loaded check valve vents are provided to release any air pressure that might build up within the gearcase and to keep the rotary cutter deck free of oil that would otherwise spew out of permanently open vents.

Wing hinge grease zerks

Bellcrank grease zerks

All pivoting points that would benefit from greasing are provided with grease zerks. Wing hinges in particular are provided with individual grease zerks. It is important to note that these points require greasing infrequently; lubrication is for protection against seizing, not wear

Tight turning radius (CX15 shown)

Hitches have a narrow profile and are 57.2 cm (22.5 in.) wide to allow a very tight turning radius.

Hydraulic Parking System

The MX15, like the HX15, CX15, HX20, and CX20, comes standard with an industry-exclusive hydraulically operated parking system with a swing-away parking stand that makes raising and lowering the cutter easy and safe. In addition, the manual implement jack is in base equipment so hitch leveling can be adjusted without hydraulics. With this addition, the cutter will remain in the same position for long time periods.

MX15 CV driveline

Six-lobe-star profile

The tractor power take-off (PTO) is connected to the MX15 splitter gearbox by a CV, Category 5, tubular six-lobe-star-profile telescoping driveline that provides smooth operation while turning and going over variable terrain:

  • Updated flex net design
  • Complies with industry standards ASAE S331 and ISO 5673

A lightweight driveline with a lock-slide collar makes it fast and easy to attach.

MX15 round-pan blade holder (stump jumper)

Gearcases and blade holders provide the following:

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

The MX15 is equipped with a round-pan blade holder for optimum cut performance, material distribution, and gearbox protection.

The MX15 gearcases comes standard with a five year warranty.

John Deere rotary cutters lead the way with innovative design, superior performance, and proven durability. Valuable features are included such as the Double-Deckerâ„¢ 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 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 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.

Rear cylinder transport lock in locked position

A transport lock flips over the lift cylinder for backup to the hydraulics when transporting the cutter.

The MX15 wing locks are located at the front-bottom section of the wings.

The wing cylinders lift and support the wings and the locks provide a secure wing-up position for transport, storage, and servicing.

The heavier HX and CX flex wings have spring-loaded wing arms with wing locks.
