🌾 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 & 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 Engine & 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 & 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 & 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.
-
Q What is the difference between the 4LZ-5 and 4LZ-7 rice combine harvester models?The main differences lie in size, power, and capacity. The 4LZ-7 features a larger cutting width (2400mm vs. 2000mm), a more powerful engine (110HP vs. 88HP), a longer threshing drum (2200mm vs. 2000mm), and wider rubber tracks (550mm vs. 450mm). The 4LZ-7 also supports 360° multi-directional grain unloading compared to the 270° unloading of the 4LZ-5, making it better suited for larger-scale operations.
-
Q Can this rice combine harvester be used in muddy or waterlogged paddy fields?Yes. The machine is designed with a raised ground clearance (minimum 300–340mm depending on model) and rubber crawler tracks, providing excellent anti-sinking performance and strong traction in soft, muddy, or waterlogged paddy fields. The optional track configurations further enhance stability in challenging terrain.
-
Q What crops can this combine harvester handle besides rice?While primarily designed for rice harvesting, this combine harvester supports multiple crop cutting stands that can be optionally installed for rapeseed, corn, millet, and other crops. This multi-purpose capability makes it a highly versatile investment for diverse farming operations.
-
Q How is straw handled after harvesting?The machine supports two straw processing modes: crushing and returning to the field (for soil enrichment), or baling for collection. The spirally arranged crushing blades ensure even spreading of straw across the field with minimal vibration during operation, reducing operator fatigue and improving field uniformity.
-
Q What safety and alarm features are included on this harvester?The harvester is equipped with a comprehensive alarm system including: grain tank full alarm, coolant temperature alarm, battery alarm, engine oil pressure alarm, and blockage alarm. Additionally, the electrical components are fully waterproof, and the recessed start switch design prevents accidental activation, ensuring safe operation in all field conditions.
-
Q Is the cab comfortable for long working hours, and how easy is maintenance?Yes. The machine features a panoramic sealed positive pressure air-conditioned cab with dual-screen monitoring and an ergonomic control handle, ensuring operator comfort during extended working sessions. For maintenance, the front-flipping hood design provides easy access to key components. The high-strength 16Mn steel frame and tungsten alloy threshing/crushing blades deliver exceptional durability and reduced maintenance frequency.
