Product Advantages
-
1Powerful Power Yuchai 320 horsepower engine, displacement of 8 liters, with large displacement plunger pump and drive motor, powerful, fast running speed and high operating efficiency.
-
2Fan Reversal Function The engine has a fan reversal function. When the water tank temperature reaches 92°C, it can automatically or manually blow back to quickly clean the corn husks adsorbed on the water tank to prevent the engine from overheating.
-
3Large Number of Peeling Rollers The number of peeling rollers reaches 20, with good peeling effect, which can effectively reduce the breakage rate of corn ears and improve the harvest quality.
-
4Full-Width Non-Row Header The full-width non-row header is suitable for large and small row spacings, with stronger adaptability, which can meet the harvesting needs under different planting modes.
-
5Large Hay Bin Volume The hay bin volume increases to 7.2 cubic meters, which is 16% larger than the industry's side-overturned 6.2 cubic meters. The hay bin has an inner flap with exclusive technology, hydraulically controlled and raised/lowered separately. Hay can be easily unloaded within 30 seconds without manual climbing.
-
6Convenient Grain Unloading The granary volume is 2.8 cubic meters, unloading height is 3.2 meters. After the hay bin is lifted twice, the unloading height can reach 4.3 meters, making it easy to unload even into earth-hauling vehicles.
-
7Hydraulic Stepless Speed Change Adopts hydraulic stepless speed change and one-lever operation of electric control handle, which is fast and more convenient. The driver can achieve precise control of speed and direction through simple operation, reducing labor intensity.
-
8Intelligent Control System After registering the mobile phone APP, the vehicle can be intelligently controlled and troubleshooted, improving the intelligent level of operation and facilitating users to understand the operating status and solve problems quickly.
-
9High-Strength Frame Chassis The frame chassis is made of 16 manganese material with good anti-bump and impact resistance. The configuration of Deere 1000 front axle and closed side reduction box makes it more suitable for complex working conditions, ensuring stability and durability of the whole machine.
