🌾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.
-
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 is larger (5900×2640×2940mm vs. 5450×2520×2870mm), heavier (3935kg vs. 3500kg), has a wider cutting width (2400mm vs. 2000mm), higher feeding speed (7kg/s vs. 5kg/s), and a more powerful 110HP engine versus the 88HP engine in the 4LZ-5. The 4LZ-7 also features 360° multi-directional grain unloading compared to 270° on the 4LZ-5.
-
Q Is this rice combine harvester suitable for use in muddy or waterlogged paddy fields?Yes. Both models are specifically designed for paddy field conditions. They feature a raised ground clearance design (minimum 300–340mm), rubber crawler tracks with excellent anti-sinking performance, and an optional track configuration for improved traction and stability in soft, muddy, or waterlogged terrain.
-
Q Can this harvester be used for crops other than rice?Yes. The harvester supports multiple crop applications. Optional cutting stands can be installed for rapeseed, corn, millet, and other crops. This makes it a versatile multi-purpose agricultural machine suitable for a wide range of harvesting needs throughout different growing seasons.
-
Q What type of engine is used and what are the fuel consumption figures?The 4LZ-5 is powered by a CHANGCHAI 88HP-GII engine (turbocharging + mechanical injection, 64.7kW, 2600 r/min), while the 4LZ-7 uses a 110HP-GIII engine (turbocharging + high-pressure common rail, 80.1kW, 2400 r/min). Both models achieve a fuel consumption of ≤35 kg/hm², ensuring economical operation across large-scale harvesting tasks.
-
Q What safety and alarm features are included in these harvesters?Both models are equipped with a comprehensive alarm system including a grain tank alarm, coolant alarm, battery alarm, engine oil alarm, and blockage alarm. Additionally, the electrical components are fully waterproof, and the recessed start switch design prevents accidental activation, ensuring safe and reliable operation in field conditions.
-
Q How is straw handled after harvesting, and what maintenance is required?After harvesting, straw can be processed in two ways: crushed and returned directly to the field, or baled for collection. The spirally arranged crushing blades ensure even spreading with minimal vibration. For maintenance, the front-flipping hood design provides easy access to key components. The machine is built with a high-strength 16Mn steel frame, and the threshing chamber and straw crushing blades are made of tungsten alloy for superior wear resistance and long service life.
