New Holland Speedrower 220, Speedrower 260 Self-Propelled Windrower PDF Repair Service Manual (Publication No. 48126544) (PIN YGG677501 and Above) Tier 4B Final

Hay harvesting leaves little room for unexpected downtime. Whether you're cutting premium alfalfa, grass hay, or mixed forage crops, every hour counts toward preserving crop quality and nutritional value. The New Holland Speedrower 220 and Speedrower 260 were engineered to combine high transport speed, excellent field maneuverability, responsive hydrostatic propulsion, and precise header control into one self-propelled harvesting platform. When servicing these sophisticated machines, accurate factory procedures are just as important as quality replacement parts.

This OEM Factory Repair Service Manual (Publication No. 48126544) is written specifically for Tier 4B Final Speedrower 220 and Speedrower 260 windrowers with PIN YGG677501 and above. It contains dealership-level repair procedures covering complete machine disassembly, diagnostics, inspection, adjustment, testing, calibration, and component overhaul. Every section follows official New Holland workshop specifications, allowing technicians and experienced owners to repair the machine safely while maintaining factory performance standards.

Built for Professional Hay & Forage Operations

Unlike conventional pull-type mower conditioners, the Speedrower 220 and 260 integrate engine power, hydrostatic propulsion, hydraulic header functions, steering, braking, electronic controls, and operator comfort into a single harvesting machine. Their balanced chassis, responsive hydraulic steering, heavy-duty drivetrain, and excellent visibility allow operators to work efficiently across large acreages while producing uniform windrows. Because every major system works together, accurate diagnosis and repair procedures are essential after long harvesting seasons or heavy field use.
