New Holland Windrower Headers - Durabine™ 416 PLUS

To maximize productivity, the all-new MowMax™ II PLUS true modular cutterbar delivers a cleaner cut. Longer knives extend each module’s cutting diameter by nearly 1 inch (25.4 mm) and turn with a tip speed of 171 mph (275 kph) at 2300 rpm on the Durabine™ 413 PLUS and 195 mph (314 kph) at 2600 rpm on the Durabine 416 PLUS and 419 PLUS, which is 14 mph (22 kph) faster than the previous series (181 mph (291 kph)). For better crop-to-knife engagement, the cast rock guards were reshaped. To improve cutting in light- or late-season crops, the profile of the cutterbar was lowered by bringing the discs closer to the cutterbar with new low profile ShockPRO™ hubs. Along with the longer knives, this design is more productive in down and tangled crops as the cutting height was lowered nearly 30%, leaving less uncut crop behind.

With every Durabine™ PLUS disc head, you get the peace of mind provided by 36 months of cutterbar warranty coverage. Coverage includes one full year of base factory warranty, plus two additional full years of MowMax II PLUS disc cutterbar warranty. It’s a New Holland exclusive – you’re backed by the best in the business.

When it comes to haymaking, your time is precious. The patented QuickMax System is standard and allows you to quickly change a damaged knife or flip an entire set of knives so you’re back to clean cutting in seconds. Fast knife changes are done with a 180-degree rotation of the discs and the use of a special tool stowed on the head, which pries down the spring plate to release the knife from the knife nut. Knife-lock technology assures knife retention in the most difficult conditions.

Durabine™ PLUS Series headers can be equipped with knives that best fit your crop and soil types. 12-degree twisted smooth knives come standard for normal cutting conditions, while 7-degree twisted smooth knives offer clean cutting and reduced blowdown in light or short crops. University studies have shown that less knife twist can also help reduce ash content. New Holland recommends 7-degree smooth twisted knives in rocky or stony conditions. Both knife types work with the QuickMax™ knife change system and feature two cutting edges so they can be flipped for double the life.

A full-length constant flow auger quickly moves crop away from the cutterbar for increased capacity, optimum feeding, uniform conditioning, and an evenly-distributed windrow. This heavy-duty, 20-inch (508 mm) auger features thick, 5/16-inch  (7.9 mm) flighting with reinforced gussets on the back to handle the heaviest crops with ease. For optimal crop flow, multiple paddles are staggered throughout the auger. To protect the conditioning rolls, a rock door is located behind the auger, which can be opened to allow debris to drop out, as well as reduce turbulence in very light crop conditions.

Diverse crop harvesting is no problem for the Durabine™ PLUS Series. You can change conditioning modules quickly to suit crops and maximize quality or remove the conditioning module entirely and outfit the header with a closure kit for wide swaths of non-conditioned hay. The large, 10+ inch (254 mm.) diameter rolls with a chevron-lug profile grip the crop and provide even flow through the rolls for uniform conditioning and fast-drying swaths or windrows. Tailor roll pressure to crop yields without tools with the turn of a hand crank that delivers consistent, thorough conditioning for all crops. All systems feature the proven torsion-bar roll-pressure system with over-center linkage that momentarily releases roll pressure, allowing slugs of crop or foreign objects to pass without plugging for non-stop mowing.

• Rubber chevron rolls – Choose gentle chevron rubber rolls for full-stem crimping and cracking of high-value legume crops. The rubber compound and wide chevron lug profile provide gentle handling to protect delicate, high-value leaves for maximum forage quality.
• Steel chevron rolls – Durable chevron steel rolls are designed for use in all crop types but show a real advantage in cane-type crops, grain forages, and extra-tall grass crops. The steel chevron lug profile provides aggressive full-stem crimping, and the rugged, all-steel construction resists wear in abrasive crops and conditions.
• B&D Roller’s “The Crusher®” Rubber Conditioning Rolls (Durabine 416 PLUS & 419 PLUS) – If you need aggressive conditioning, B&D Roller’s proprietary, repairable rubber compound provides longer wear and softer hay. Effective for all forages, these factory-installed rolls completely flatten the stem with minimal loss to retain valuable nutrients for a higher Relative Feed Value (RFV).

Fast drying requires the crop to be evenly distributed over a wide swath. Durabine™ PLUS disc headers provide extra crop control surfaces behind the conditioning system. The new swath baffle is 8 inches longer and has additional adjustable control surfaces that let you form the perfect swath for nearly any condition. For wide swaths, the baffle is lowered so the adjustable swath spreading wedges engage the crop stream to improve uniformity. When windrowing, the baffle is raised so the adjustable windrow fins engage the crop and improve center fill. Windrow shields are optimized to create a tunnel effect with a fluffing baffle, guiding crop into the windrow and creating a well-defined windrow edge.

When the conditions get tough, rest assured that Speedrower® 220 PLUS and 260 PLUS windrowers will maintain impressive cutting performance. In comparison to prior models, the new Danfoss® Hydraulic electronically-controlled pump provides increased hydraulic flow while turning at a slower rated engine speed. To provide quieter header drive and improved oil flow, the header drive is transmitted through a hydraulic distribution block and low back-pressure flat-faced couplers. High-performance Bondioli hydraulic motors on the head increase the header drive working pressures and provide superior reliability.
