Brave 4YZ-5A/5B/5C/5D self-propelled corn harvester product introduction

1. Adopting a blade pulling type ear picking box and cutting platform, the stem pulling speed is fast and the ear picking effect is good; The elevator floats and removes impurities, with a dedicated support device for forced feeding, making it more suitable for harvesting fallen corn with high harvesting efficiency;
2. The cutting speed of the harvester is adjustable, which is more suitable for harvesting operations under different crop maturity and straw conditions;
3. Adopting a peeling structure consisting of 6 sets of rubber rollers and cast iron rollers, the peeling effect is good, with a peeling rate of over 95% and no grain breakage;
4. Add a grain impurity removal fan to ensure clean and debris free grain recycling;
5. The engine adopts double-sided power transmission, with strong power and smooth transmission; Adopting electronic fuel injection technology to ensure optimized configuration of power, fuel consumption, and emissions;
6. Adopting a tightly sealed engine fireproof cover to effectively prevent debris from entering the enclosed space of the engine; Adopting a dedicated water tank for National III engines and an integrated intercooler combination water tank, with high heat dissipation efficiency and equipped with a reversing fan for easier cleaning;
7. Adopting a vertical control box for more comfortable and convenient operation;

1. Fast peeling speed, high peeling rate, and no cracking.
2. Strong power, using a 190 horsepower six cylinder engine, with high work efficiency.
3. Knife pull stem type ear picking box and cutting platform have fast stem pulling speed and good ear picking effect.
4. The overall appearance design of the vehicle provides a more cohesive and coordinated body.
5. Grain fan is standard, making the grains cleaner.
6. Floating sorting is standard, and the secondary cleaning effect of corn stalks is stronger.
