2024 New Holland Discbine 312R+

New Holland Agriculture North America is once again redefining the disc mower-conditioner with the introduction of the new Discbine® PLUS Series. For modern hay producers, New Holland understands they need equipment that improves their productivity and optimizes their quality to preserve valuable feed nutrients. That’s exactly what New Holland designed the Discbine PLUS Series to help customers do.

“A disc mower-conditioner isn’t a genuine Discbine unless it’s built and backed by the best in the business. From the hitch to the swath doors, these four models are designed and built with pride in New Holland, Pennsylvania,” says Sally Johnson, Vice President for New Holland Agriculture North America.

“The Discbine PLUS models have bold, new styling and yellow accents to signify commercial-grade performance. They’re built with the same DNA, durability and superior quality that customers know and expect, but we’ve focused on enhanced cutting and swath controls for greater overall performance,” states Jordan Milewski, Conventional Haytools Marketing Manager for New Holland Agriculture North America.


These machines include a maneuverable center-pivot tongue and standard swivel gearbox hitch that permit confident, fast operation and easy, trouble-free headland turns.

“When it’s your crop on the line, it’s about easier harvesting, better yields and improved feed quality. These Discbines help customers check all three boxes,” Milewski says.

High-capacity, clean-cutting, and durable mowers
All Discbine PLUS models utilize the MowMax™ II PLUS disc cutterbar with the QuickMax™knife-change system. This newly redesigned cutterbar delivers the cleanest cut yet from New Holland and commercial durability. It is similar to the cutterbar featured on Durabine™ PLUS disc headers for Speedrower® PLUS self-propelled windrowers.

Delivering a faster tip speed, the cutterbar comes equipped with longer knives. This slimmer cutterbar improves cut quality, while a 30% lower cutting height leaves less behind in down and tangled crops. For cleaner cutting in light or late-season crops, the reshaped rock guards enhance crop-to-knife engagement.

Saving hassle, time and repair costs by fending off potential damage, these models utilize ShockPRO™ disc drive hubs that absorb impacts to protect drive components. These components are also quick to replace in the field, enabling haymakers to keep mowing when conditions are right. For additional peace of mind, all Discbine PLUS models come with 36 months of factory cutterbar warranty coverage.

Better control equals better windrows
For the best conditioning and fast dry down, the WideDry™ conditioning system is sized for each model to deliver uniform conditioning and smooth crop flow. Conditioning system options include New Holland’s chevron intermeshing rubber rolls or chevron intermeshing steel rolls* with proven torsion bar pressure system for non-stop mowing. For optimal grass hay conditioning, the LeaningEdge™ flail tine conditioning system is available**.

Improving crop dry down, Discbine PLUS models offer increased crop control when windrowing or swathing. A 5-inch longer horizontal swath gate fitted with adjustable crop spreading wedges help break up crop streams. They're also fitted with adjustable crop fins for added windrow control.

“Discbine PLUS models can make narrow windrows as small as 3-feet wide or up to 8-feet wide for fast drying with the two widest models,” Milewski states.

The windrow forming shields are also 5-inches taller than previous Discbine models and work with the swath gate to produce a tunnel effect. Specifically, this taller design, with greater curvature at the bottom provides more precise windrow control, helping to tuck the edges in for neater-looking swaths with improved dry down.
