Built with a heavy-duty pickup reel, synchronized auger feeding system and reliable driveline components, these headers are engineered to deliver smooth crop flow into compatible FR Series forage harvesters. When operating in dusty, high-acreage harvesting conditions, regular servicing is essential to maintain pickup performance and prevent costly downtime. This OEM factory repair manual provides dealership-level repair procedures for accurate diagnostics, professional repairs and complete header overhauls.

Built for Efficient Windrow Pickup

The 300FP and 380FP pickup headers are engineered for high-capacity forage harvesting where smooth crop transfer directly affects chopping efficiency. Their wide pickup reels with closely spaced spring tines gently lift hay, grass and wilted forage from the windrow before transferring material through a large-diameter cross auger into the forage harvester feed rolls. Heavy-duty drive chains, reinforced side frames and adjustable gauge wheels help maintain stable operation across uneven terrain while reducing crop contamination and improving harvesting productivity.
