Overview
Wuzheng MD554 wheeled tractor
Product Details
Product Highlights:
The MD series tractor is a high-end medium horsepower tractor jointly developed by Wuzheng Group and Europe. It is the first product in the same horsepower range in China to adopt synchronizer shifting technology. It has humanized design and excellent manufacturing technology. During use, you will experience excellent overall performance and fuel economy.
Equipped with domestically renowned engines, the whole machine has low vibration, low noise, and low fuel consumption.
Adopting a fully enclosed cab, all noise and vibration are cut off, providing the most comfortable driving environment for drivers.
The transmission system adopts a three-axis layout, and the box body is a cylindrical structure. The chassis structure has high strength and reliability.
The whole machine adopts a 16+8 variable speed gear setting (optional crawl gear is 24+12), which enables the best performance of various operations.
The tractor has a wide speed range, which can adapt to heavy-duty crawling operations of 0.2~0.3km/h, as well as road transportation operations of 35~40km/h.
The speed shift of the transmission system adopts synchronizer shifting, which feels like driving a car, and is the first time that a domestic medium horsepower tractor adopts synchronizer shifting.
Adopting an independent clutch control, the operation of the working machinery is not affected by gear shifting and parking.
The front drive shift of the tractor is operated by a clutch, which can be switched at any time during field work.
The power output can adopt three speeds of 540/750/1000, and can be optionally equipped with synchronous power output to meet special field operation requirements such as precise sowing.
Assemble 2 sets of external hydraulic output valves for easy installation of various work tools.
