New Holland H8060, H8080 Windrowers PDF Repair Service Manual (Publication No. 84211407 | PIN Y8G661200 & Above)

Large-scale hay production demands more than cutting speed—it requires consistent crop conditioning, dependable hydraulic performance and a machine capable of operating long hours without sacrificing productivity. The New Holland H8060 and H8080 Windrowers were engineered for professional forage producers, custom harvesting contractors and large livestock operations that require exceptional daily output. Featuring powerful 6-cylinder diesel engines, dual-range hydrostatic propulsion and compatibility with disc, draper and sickle headers, these windrowers are designed to harvest thousands of acres with outstanding reliability. Machines covered by this manual begin with PIN Y8G661200 and above.

Designed for High-Output Commercial Hay Operations

The H8060 delivers approximately 190 horsepower while the flagship H8080 increases output to approximately 226 horsepower, allowing operators to run larger disc headers, wide draper platforms and high-capacity mower-conditioners. A suspended operator cab, hydrostatic steering, independent hydraulic header flotation and optional suspended rear axle improve ride quality during long harvesting days while maintaining excellent cutting performance across rough terrain. These machines are widely used for harvesting alfalfa, grass hay, forage crops and specialty crops.
