1. Efficient homework
By using a vertical axial flow threshing drum, efficient threshing can be achieved with minimal loss and clean threshing;
The new adjustable double-layer vibrating screen has better cleaning performance;
Side high position mechanical automatic unloading device with hydraulic control, saving manual unloading labor;
Mingyou Power, turbocharged, up to 88 horsepower, powerful;
2. High quality and reliable
Enhanced walking chassis, reliable operation;
Imported high-grade transmission belt with long service life;
Imported bearings and oil seals for more reliable use;
Enhanced heat treatment of agitator blades, concave plate screens, drum cover guide bars, threshing drums, etc., resulting in a longer service life
3. Easy to operate
Adopting a continuously variable transmission walking device, only one handle is used to control forward and backward, and the HST with increased capacity is more effortless to operate than before;
One lever control, using one handle to achieve left and right turning and lifting of the cutting table, comfortable operation;
Install comfortable seats to ensure that the operator is not easily fatigued even after prolonged work
4. Easy to maintain
The threshing drum cover and side cover can be easily opened without tools;
The grain box can also be cleaned and inspected, and the cleaning and inspection of the large grain box and threshing section are very simple;
It is easy to clean and inspect the interior by simply loading and unloading the sorting boxes;
The engine hood can be opened without tools, making maintenance convenient
5. High ground clearance, low specific pressure, good passability
The ground clearance is up to 300mm, with a wide track configuration and a low grounding ratio, making it easy to pass through muddy fields;
