New Holland HW345, HW365 Self-Propelled Windrower PDF Repair Service Manual (Publication No. 87576216)

The New Holland HW345 and HW365 Self-Propelled Windrowers are designed for high-output forage operations where cutting speed, conditioning quality and machine reliability directly affect harvesting productivity. Developed for professional hay producers and custom operators, these windrowers combine a powerful self-propelled chassis with a high-capacity disc header, crop conditioning system and responsive hydrostatic drive to produce clean, uniform windrows across a wide range of forage crops.

Long harvesting days expose the cutterbar, conditioning rolls, header suspension, hydraulic pumps, hydrostatic transmission and steering systems to constant operating loads. This OEM Factory Repair Service Manual (Publication No. 87576216) provides detailed dealership workshop procedures for inspection, diagnostics, repair, calibration and complete component overhaul, helping technicians restore original factory performance while minimizing costly downtime during the hay season.

Engineered for Maximum Forage Productivity

The HW345 and HW365 are built to harvest large acreages efficiently while maintaining consistent crop conditioning. Their floating cutting platform follows uneven terrain for a clean cut, while the conditioning system accelerates crop drying by producing a uniform windrow. Combined with precise hydraulic controls and dependable hydrostatic propulsion, these machines deliver excellent productivity throughout demanding harvesting conditions.
