🌾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 their size, power, and capacity. The 4LZ-7 features a larger cutting width (2400mm vs. 2000mm), a longer threshing drum (2200mm vs. 2000mm), a more powerful engine (110HP vs. 88HP), a wider rubber track (550mm vs. 450mm), and a 360° multi-directional grain unloading system compared to the 270° system on the 4LZ-5. The 4LZ-7 is better suited for large-scale operations requiring higher productivity.
-
Q Is this rice combine harvester suitable for muddy or waterlogged paddy fields?Yes. The machine is specifically designed for paddy field conditions. It features a raised ground clearance of 300–340mm, rubber crawler tracks for superior flotation, and an anti-sinking chassis structure. The optional track configurations further enhance performance in extremely soft or waterlogged soil conditions, preventing the machine from getting stuck during operation.
-
Q Can this harvester be used for crops other than rice?Yes. The rice combine harvester supports multi-crop harvesting. By installing optional cutting stands, it can be configured to harvest rapeseed, corn, millet, and other crops. This makes it a highly versatile machine for farms that grow multiple types of crops throughout the year.
-
Q What type of cab does the harvester have, and is it comfortable for long working hours?Both models are equipped with a luxury air-conditioned cab featuring a panoramic sealed positive pressure design. The cab includes dual-screen monitoring, an ergonomic operating handle, waterproof electrical components, and a recessed start switch to prevent accidental activation. These features ensure operator comfort and safety during extended working hours in the field.
-
Q How is the straw handled after harvesting?The machine supports two straw processing methods: crushing and returning to the field, or baling for collection. The spirally arranged crushing blades ensure even spreading of straw across the field with minimal vibration during operation. This flexibility allows farmers to choose the most suitable method based on local agricultural practices and soil management needs.
-
Q What alarm and safety systems are included in the harvester?The harvester is equipped with a comprehensive alarm system that monitors multiple critical parameters, including grain tank level, coolant temperature, battery status, engine oil pressure, and blockage detection. These real-time alerts help operators respond quickly to potential issues, reducing downtime and preventing mechanical damage during field operations.
