Product Selection · Application Guide
Header reel, straw chopper, and steering — three hydraulic functions, one supplier: BM3Y, ZBMR, and the BPBS steering unit on a combine harvester.
Harvest windows are short: a combine runs long shifts through dusty, high-vibration conditions, and every hydraulic function has to keep pace with the crop. Sourcing the drives from one maker keeps interfaces matched and procurement simple.
Motor roles in this machine
- BM3Y — header reel drive: Direct-flange orbital motor turns the reel at crop-matched speed with steady torque as feed density varies. BM3 reference →
- ZBMR — straw chopper drive: Orbital motor with integrated brake stops the chopper quickly and safely for clearing blockages.
- BPBS — steering unit: Full-hydraulic steering holds a straight cut line for hours with light effort. BPBS reference →
