Crop harvesting machinery for harvesting grains and straws of cereal crops such as rice and wheat. The development trend of harvester is to use new materials to further reduce weight; Adopt low vibration engine, advanced vibration reduction and isolation device and reasonably configure parts to reduce the harm of vibration to human body.
