2027 New Holland MegaCutter 510 Front Mounted Disc Mower

UP TO 50 ACRES PER HOUR
 The importance of effective and efficient conditioning is clear. MegaCutter™ mounted disc mowers and disc mower-conditioners match capacity to your imagination. 

THE COMBINATION THAT’S RIGHT FOR YOU 
New Holland offers triple-swath productivity both with conditioning and without to fit your crops, your tractor horsepower and your budget.

DURABILITY TO HANDLE TOUGH CONDITIONS 
Every part of the MegaCutter™ system is ruggedly built for high-speed mowing. Keeping knives sharp is easy with the standard quick-change knife system.

ROLL OR FLAIL CONDITIONING 
If your crops require conditioning, MegaCutter™ disc mower-conditioners offer you the choice of gentle rubber chevron intermeshing rolls perfect for legume crops or steel V-tine flail conditioning for grass hay.

CAPACITY AS BIG AS YOUR HARVESTING AMBITIONS
Today’s commercial operations and custom harvesters know preserving forage quality is like money in the bank. It’s a process that begins when the first crop falls and only ends when the bales are stacked and the bunk is packed. New Holland can help you reach your goal with high-capacity MegaCutter™ solutions.

THE IDEAL LOW-HORSEPOWER PLAIN MOWING COMBINATION FOR SILAGE MAKING

MegaCutter™ 510 and 531 plain disc mowers give you the perfect balance of forage quality and a low power requirement when you’re making chopped hay silage that offers high retained quality without conditioning. These plain mower versions cut crop closely, cleanly and quickly, leaving it in a consistently wide swath. The non-conditioning MegaCutter versions cut over 30 acres every hour with as little as 150 horsepower. You cover more acres using less time and fuel to save money.

HARVEST FLEXIBILITY WITH EFFECTIVE CROP CONDITIONING

Quality starts with planting a good stand and then harvesting at peak quality and the ideal moisture. When your operation is a mix of chopped silage, baling, wrapping, and even late-season dry hay, and you have hundreds of acres to mow before lunch, the importance of effective conditioning is clear. Extra-wide MegaCutter™ 512 and 533 disc mower-conditioners give you the faster crop drying essential to reaching the ideal moisture fast so you can move on to the next field.

FINGERTIP-MANAGED PRODUCTIVITY ACRE AFTER ACRE

Simple, smooth management of large combination machines is essential for maximum productivity. The MegaCutter™ 533 is ISOBUS compliant, so it pairs seamlessly with the tractor. You can handle all critical machine functions through the IntelliView™ IV large color touchscreen display or using the optional joystick. For late-model tractors, an optional non-ISOBUS joystick control connects directly to the mowers. The MegaCutter 531 plain mower model requires only three double-acting hydraulic remotes with no need for a control box.

Features May Include: 

MEGACUTTER™ DISC CUTTERBAR

STANDARD QUICK-CHANGE KNIFE SYSTEM KEEPS YOU CUTTING SHARP

• Sharp knives give you the clean cut you want with less crop left behind. As a result, you harvest more tons, get fast regrowth and assure your forage quality for the next cutting. Keeping knives sharp is easy with the standard quick-change knife system. It allows you to change damaged knives fast or flip an entire set and get back to mowing pronto to keep on your mowing schedule.

CLEAN CUTTING AND RELIABILITY ARE STANDARD ON EVERY MODEL

• Whether you’re cutting your own fields or working as a contractor, clean cutting without slowdown is what you expect. The MegaCutter™ disc cutterbar provides a clean cut with minimal tilt, even in thick and tangled crops. The round disc profile is less susceptible to impacts than other disc shapes and each disc drive is fitted with a drive protection system.

RESPONSIVE SUSPENSION TO ADAPT TO CHALLENGING TERRAIN

• The MegaCutter™ 510 and 512 front-mounted models offer a broad suspension range, with up, back and angular motion to react to changing terrain and protect both machine and crop stubble.

PROTECTION, SPEED AND EFFICIENCY

• The MegaCutter™ 531 rear plain disc mower is equipped with a non-stop breakaway and automatic reset to protect the cutting heads. Each pendulum-arm-mounted head automatically swings up and back and then returns to the working position to maintain your pace.

ADVANCED 3D SUSPENSION

• The MegaCutter™ 533 rear disc mower-conditioner is fitted with an advanced three-dimensional suspension that assures clean cutting, machine protection, and high working speeds. Unlike the pendulum design, quad-link arms attach each head to the main frame so they are free to move independently up and back.

CONDITIONING SYSTEMS

STEEL FLAIL TINE CONDITIONING

• Steel flail tines are positioned at an angle to the rotor’s center, providing increased outward crop pressure against the adjustable conditioning hood and improving swath and windrow formation. You can adjust the hood to change the conditioning intensity. The semi-swinging flail tines allow obstructions to pass, for better protection compared to fixed poly or steel tines. And unlike conventional, free-swinging tines, they cannot swing back over center, but are held in the ideal place by centrifugal force for efficient and effective conditioning and uniform swath and windrow formation.

RUBBER CHEVRON INTERMESHING ROLLS

• Rubber chevron intermeshing rolls provide full-stem crimping and cracking with a scrubbing action while handling the leaves of high-value feeds delicately, making it the ultimate solution for alfalfa and clover. You get gentle handling while making fast-drying swaths.

HIGHER RETAINED QUALITY THROUGH FAST DRYDOWN

• Faster hay drying not only means beating the weather, it allows you to get crop out of the field with maximum feed quality. New Holland offers three effective solutions for fast drying of high-quality feed, including gentle rubber chevron intermeshing rolls for alfalfa and other legume crops, flail tine conditioning for grass hay, and a lower-horsepower model with no conditioning that’s ideal for silage making.

PRECISION TECHNOLOGY

FASTER SPEEDS, FASTER RESPONSE

• Automatic steering control maintains pass-to-pass accuracy, allowing operators to use faster working speeds and reducing fatigue. When operators are free from making continuous manual adjustments, they are better able to react to obstructions hidden in the field.

EFFICIENT CHOPPING

• The IntelliSteer™ system takes control to mow parallel swaths that are faster and easier to pickup with a merger so you get long, straight merged windrows that are efficiently handled by the self-propelled forage harvester.

MAXIMUM EFFICIENCY

• Maximize MegaCutter™ triple disc mower-conditioner productivity and performance with a New Holland tractor equipped with the IntelliSteer™ automatic steering system. New Holland Precision Land Management™ (PLM) solutions help you to improve overall operational efficiency resulting in the lowest possible cost per acre.

SMARTER MOWING

• The IntelliTurn™ Intelligent Automatic End of Row Turn System keeps control on headlands, automatically calculating and executing end-of-row turns, without the need for manual steering. IntelliTurn utilizes NHDrive technology, making practical automation possible today.
