New Holland 346W, 356W, 366W Headers SP Forage Pickup PDF Repair Service Manual (Publication No. 87576103)

The New Holland 346W, 356W and 366W SP Forage Pickup Headers are designed to maximize the productivity of self-propelled forage harvesters by collecting pre-cut windrows cleanly and delivering a smooth, uninterrupted crop flow into the feeding system. Built for high-volume forage harvesting, these pickup headers efficiently gather hay, straw and other windrowed crops while minimizing field losses and maintaining consistent feeding performance under varying crop conditions.

Daily harvesting exposes the pickup reel, tine bars, augers, feed drums, chain drives, hydraulic lifting components and driveline assemblies to continuous wear. Accurate servicing requires factory repair procedures and precise adjustment specifications. This OEM Factory Repair Service Manual (Publication No. 87576103) provides dealership-level instructions covering inspection, diagnostics, adjustment, overhaul and complete component rebuilding, helping technicians restore reliable pickup performance and reduce downtime during forage harvesting.

Optimized for Uniform Crop Feeding

The 346W, 356W and 366W pickup headers are engineered to deliver smooth crop transfer from the windrow to the forage harvester without plugging or excessive crop loss. Adjustable pickup tines, reinforced augers and durable feed components allow the headers to maintain consistent feeding across different crop volumes while protecting valuable forage quality.
