Features include:

• Two high-quality, reversible knives per disc on four, five or six oval cutting discs
• Rock guards and skid shoes to protect discs and carry the cutterbar over uneven ground
• An enclosed gear-driven cutterbar that provides years of reliable service
• A 540-rpm PTO driveline with overrunning clutch to protect the tractor driveline
• Adjustable flotation springs for changing cutterbar ground pressure
• An articulation joint that allows mowers to operate above and below horizontal
• A spring-loaded breakaway latch that protects the cutterbar
• A single-acting hydraulic cylinder that easily lifts the cutterbar after each pass
• 3-point hitch mounting

Heavy-Duty MD72, MD82 AND MD92

• Cutterbar shock protection standard
• Handles most any crop condition, from wet field to downed crops
• Built with heat-treated components to stand up to extreme conditions
• Uses a close-coupled design for maximum ride stability, especially in tight turns?

Modular Cutterbar

• Results in superior crop flow that reduces streaking
• Ensures quick mowing
• Heavy-duty frame and rugged canopy use a cantilevered design for smooth crop flow across cutterbar?

Smooth-profile Discs

• Lift crop into the cutting zone for plug-free mowing, provides a consistent swath for more even drying
• Each disc is 3/16-in (4.8-mm)-thick and heat treated to resist damage
• Discs are shielded by 1/4-in (6.4-mm)-thick by 8-in (203-mm)-wide skid shoe. The shape of skid shoes work with the tilt of the cutterbar to provide a wide range of mowing heights
• The gearbox oil in modular cutting discs performs up to 200 hours between changes ?

Rotating Modular Knife Blades

A rotating modular knife blade provides thorough and uniform crop cutting.

• Each disc houses two knife blades
• Blades rotate at 3,000 rpm
• Disc hardware is specially designed and treated for extreme durability to resist abrasive conditions

Independent, Sealed and Self-Contained Modules Resist Damage

• Short, independent splined driveshaft sections link modules
• Shafts are made from alloy steel with roll-formed splines for strength and are hardened for added durability

Maintenance

• MD72, MD82 and MD92 — engineered for ease of maintenance
• Reversible knife blades change quickly without raising the cutterbed
• Knife bolts are located on top of the modular discs for easy access
• Discs can be in any position when performing maintenance
• If an object is struck during operation, a spring-loaded cutterbed breakaway latch releases
• Greasable, sintered bushings ensure the cutterbar releases fully when the breakaway latch is activated
• A heavy-duty, puncture-resistant curtain provides protection for operator and bystanders
• A polyester-vinyl curtain tilts the crop forward for better flow across the cutterbar
• High-stress components are protected from debris by T-seal washers and lip seals

Hassle-free Transport

• When in the transport position, the MD72, MD82 and MD92 become compact packages with ride stability and plenty of ground clearance.
• The cutterbar transport lock automatically engages for a secure hold
• The cutterbar is spring-balanced from end to end: allows the mower to glide over uneven terrain smoothly and can be adjusted for all conditions.
• The V-belt tension spring has an easily visible indicator for quick inspection of belt tension: changing belt tension is convenient with single-point adjustment and no shields to remove.
• A tethered pin activates the flotation spring for cutting and is repositioned when using the parking stand
