Product Features: |
"Gold Dafeng"4LZ-9AThe self-propelled grain combine harvester adopts the tangential flow + transverse axial flow threshing and separation technology. The feed rate reaches 9 kg/second, which can quickly process grain and improve harvesting efficiency. The one-lever control system is adopted, which is simple and efficient to operate. The chassis is made of high-strength material and is more durable. The threshing and separation method of tangential flow + transverse axial flow is adopted, and the threshing effect is good. |
1. The grain unloading height is 3.4 meters, and the inner diameters of the vertical and horizontal unloading cylinders are thickened to 300mm and 260mm respectively, making the grain unloading more efficient;
2. The grain bin is lengthened in the left and right directions, the overall height is increased, the volume is increased, and more loading and less unloading are allowed.
3. The 350L fuel tank meets the endurance of one day's operation.
4. The 10-inch display, engine and reverse two-way 720P high-definition video monitoring.
5. The key parts such as the intermediate shaft, drum shaft, and bridge driving shaft are imported maintenance-free bearings with strong load-bearing capacity and long durability.
6. The transmission belt adopts a black toothed belt with high transmission efficiency, strong tension, good heat dissipation, no slipping, and no speed drop.
7. The cutting table returns to its position with one button, and the cutting height adjustment is more convenient.
8. One-lever control, efficient and convenient.
9. The standard air conditioner and washbasin save the need for later installation.
10. The walking clutch hydraulic power assist is light and labor-saving. |
