Dongfeng Jingguan HF738G (4LBZ-148) Half Feed Harvester Product Features
1. High performance engine

High performance, high quality, low fuel consumption, powerful, National IV emission 73 horsepower engine. Achieve excellent work efficiency with a maximum working speed of 1.7m/s.
2. Rotten fields have good passability

230mm high ground clearance, suitable for various environmental operations, better passability in wet and rotten fields, and higher operational efficiency.
3. Centralized configuration of operations, saving time and effort

Centralized setting of operation seats, easy and convenient to operate. Say goodbye to tedious operations, users can get started faster, saving time, effort, and worry.
Equipped with automatic feeding depth function and improved electronic control level, even if the harvested crops are uneven, high-precision sensors can keep the depth of the fed crops consistent and enter the threshing drum, improving threshing accuracy and efficiency.

4. IQ throttle
Automatically maintain the engine speed that is most suitable for harvesting operations, without the need for adjustment, resulting in reduced fuel consumption.

5. Automatic cleaning device
Through electronic control, it can automatically adjust and select the appropriate air volume during turning to reduce threshing losses.
6. Improvement of threshing performance


Large diameter 462mm, extended threshing drum 1050mm, three drums, with secondary threshing and cleaning functions, good cleaning effect, and less scattering.
7. Large capacity grain tank

Large capacity of 1300L, reducing the number of grain releases, ensuring long-lasting harvesting operations, and improving efficiency.
8. Unique cross type finger tapping, continuous harvesting is more reassuring

The unique cross dial finger design in the industry makes it difficult to block the machine and provides a stable helper for work.
By continuously picking up crops and smoothly and neatly feeding them into the threshing section, it maximizes the satisfaction of the operator's long-term work needs.
Adopting reinforced resin materials, it is corrosion-resistant, has high strength, and good durability.
9. Imported vertical baler


A vertical baler that can be equipped with high-quality well closing technology, with electronic control design and adjustable baling position, integrating speed and accuracy, allowing straw to be fully utilized, saving time and effort, and having high economic value.
