Information

The 2026 New Holland 310R Plus Discbine is a robust, center-pivot disc mower-conditioner built for dependable hay cutting and conditioning on small to mid-size farms. It delivers a 10 ft 1 in (3.0 m) cutting width and is designed to operate efficiently with tractors in the ~80 hp PTO range, using a 1,000 rpm PTO (with 540 rpm optional). At its heart is the advanced MowMax™ II PLUS modular cutterbar with six discs and quick-change knives, offering smooth, consistent cutting and simplified maintenance. Cutting height is adjustable from approximately 0.5? to 2.6?, with optional adjustable skid shoes allowing higher lift where needed, and the header’s hydraulic tilt and adjustable flotation help the unit follow ground contours for reduced scalping and cleaner stubble.

The “R” unit includes rubber-on-rubber chevron conditioning rolls that aggressively crimp stems for faster dry-down while maintaining crop quality in sensitive hay types like alfalfa. Drive protection is enhanced by the ShockPRO™ system, which helps safeguard the cutterbar from impact damage. Operators can form a 6-foot maximum swath and adjustable 3'–6' windrows for efficient field flow and dry-down. The center-pivot hitch design improves visibility and maneuverability at headlands, and the mower-conditioner sits in a compact transport position with about 10 ft 4 in width for easy road travel. The machine typically weighs in the 5,700–5,800 lb (˜2,600–2,630 kg) range equipped with rubber rolls. Hydraulic hookups generally include at least one double-acting and one single-acting circuit for conditioning and flotation functions, plus a 7-pin electrical connector for transport lights.
