Product advantages
Highly adaptable chassis for paddy fields: Featuring a raised ground clearance design, with a minimum ground clearance of 330–340mm, and optional track configuration, it offers excellent anti-sinking performance in muddy fields and strong maneuverability. The header is compatible with plate or cage-type dividers, providing good harvesting results for lodged rice. The blade guard design allows for low-cutting operations and reduces the risk of weed entanglement.
Highly efficient threshing and low-loss cleaning: Long-axis flow extended drum (2.2 meters and above), with an arc-shaped thickened stainless steel plate at the threshing chamber feed inlet; equipped with a new adjustable fish-scale screen and high-efficiency blower, ensuring thorough secondary cleaning with low breakage and entrainment losses; pre-drilled holes for cutting long stalks effectively address the problem of blockage caused by high humidity and long straw.
Powerful power and high operating efficiency: Powered by a Yuchai National II engine, providing ample power reserves and economical fuel consumption; a large feed capacity combined with a wide header, optimized and upgraded conveyor bridge, and floating wheels that adapt to the feed volume; precise matching of the hydraulic system and gearbox ensures fast transfer speeds and stable and reliable operating efficiency.
Comfortable and easy-to-maintain operation: The panoramic sealed positive pressure air-conditioned cab features dual-screen monitoring and an ergonomic handle for convenient operation; electrical components are waterproof, and the recessed start switch prevents accidental operation; the entire machine uses a high-strength 16Mn steel frame, and the threshing chamber and straw crushing blades (made of tungsten alloy) are highly wear-resistant; the front-flipping hood design facilitates daily maintenance and repair.
Multi-purpose and straw processing: Multiple crop cutting stands can be optionally installed for rapeseed, corn, millet, etc.; straw processing supports crushing and returning to the field or baling, with spirally arranged crushing blades for even spreading and minimal vibration during operation.
