New Holland Speedrower 160 Self-Propelled Windrower PDF Repair Service Manual (Publication No. 47824873) Tier 4B Final

For premium hay producers, harvest timing is measured in hours—not days. A failed hydrostatic transmission, inaccurate header flotation or hydraulic fault during peak cutting season can reduce forage quality and increase operating costs. The New Holland Speedrower 160 was developed as a highly maneuverable self-propelled windrower that combines fuel-efficient power, smooth hydrostatic travel and precision header control into a compact harvesting platform. To keep every system operating at factory performance, New Holland produced this OEM workshop manual for dealership technicians and professional repair facilities.

This OEM Factory Repair Service Manual (Publication No. 47824873) provides detailed repair procedures for the Tier 4B Final New Holland Speedrower 160. From engine diagnostics and transmission calibration to steering repairs, hydraulic testing and complete machine overhaul, every repair sequence follows official New Holland workshop standards. Rather than simply replacing parts, the manual explains how to inspect, measure, rebuild and verify each system before returning the machine to the field.

Built for Smaller Fields Without Sacrificing Productivity

The Speedrower 160 is engineered for livestock farms, dairy operations and commercial hay producers looking for excellent fuel economy and reliable harvesting performance. Powered by a 4.5 L turbocharged Tier 4B engine producing 150 rated horsepower and up to 161 maximum horsepower, it features a dual-range hydrostatic transmission, 120-gallon fuel tank, electronic engine management and compatibility with New Holland Discbine®, draper and sickle headers. Its compact footprint allows excellent maneuverability while maintaining high field productivity. :contentReference[oaicite:2]{index=2}
