Rotary Disc Mowers 

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 

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

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 shoes
  • 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

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
  • Greaseable, 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
  • 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
  • No shields to remove
• A tethered pin activates the flotation spring for cutting and is repositioned when using the parking stand
