Product Advantages
-
1Powerful Power Yuchai 320 horsepower engine, displacement of 8 liters, with large displacement plunger pump and drive motor, powerful, fast running speed and high operating efficiency.
-
2Fan Reversal Function The engine has a fan reversal function. When the water tank temperature reaches 92°C, it can automatically or manually blow back to quickly clean the corn husks adsorbed on the water tank to prevent the engine from overheating.
-
3Large Number of Peeling Rollers The number of peeling rollers reaches 20, with good peeling effect, which can effectively reduce the breakage rate of corn ears and improve the harvest quality.
-
4Full-Width Non-Row Header The full-width non-row header is suitable for large and small row spacings, with stronger adaptability, which can meet the harvesting needs under different planting modes.
-
5Large Hay Bin Volume The hay bin volume increases to 7.2 cubic meters — 16% larger than the industry's 6.2 m³ side-overturned standard. With exclusive hydraulic inner flap technology, hay can be easily unloaded within 30 seconds, cleaner, without manual climbing.
-
6Convenient Grain Unloading The granary volume is 2.8 cubic meters with an unloading height of 3.2 meters. After the hay bin is lifted twice, the unloading height reaches 4.3 meters — even a large earth-hauling vehicle can be easily unloaded.
-
7Hydraulic Stepless Speed Change Adopts hydraulic stepless speed change and one-lever electric control handle operation — fast and convenient. Drivers achieve precise control of speed and direction through simple operation, reducing labor intensity.
-
8Intelligent Control System After registering the mobile phone APP, the vehicle can be intelligently controlled and troubleshot remotely, improving the intelligent level of operation and enabling users to understand operating status and solve problems quickly.
-
9High-Strength Frame Chassis The frame chassis is made of 16 manganese material with excellent anti-bump and impact resistance. Equipped with Deere 1000 front axle and closed side reduction box for stable operation under complex working conditions.

Frequently Asked Questions
-
QWhat engine does the 4YZPSJ-4C corn combine harvester use, and what is its power output?The 4YZPSJ-4C is equipped with a Yuchai 320GIII engine — a six-cylinder, in-line, water-cooled, high-pressure common rail engine with a rated power of 320HP (235.2KW) and a rated speed of 2300 r/min. The 8-liter displacement combined with a large plunger pump and drive motor ensures powerful performance and high operating efficiency.
-
QWhat row spacing is the 4YZPSJ-4C compatible with?The machine features a full-width non-row header with an adjustable row pitch of 550–650mm and a working breadth of 2600mm. This design makes it compatible with both large and small row spacings, adapting to various corn planting modes and field conditions.
-
QHow does the hay bin unloading system work on the 4YZPSJ-4C?The hay bin has a volume of 7.2 cubic meters — 16% larger than the industry-standard 6.2 m³. It is equipped with an exclusive hydraulic inner flap technology that raises and lowers separately. The entire hay unloading process can be completed within 30 seconds hydraulically, eliminating the need for manual climbing and ensuring cleaner unloading.
-
QWhat is the grain tank capacity and unloading height of this harvester?The grain tank has a capacity of 2.8 cubic meters. The standard unloading height is 3.2 meters, and after the hay bin is lifted twice, the unloading height can reach up to 4.3 meters — making it easy to unload into large transport vehicles such as earth-hauling trucks.
-
QDoes the 4YZPSJ-4C support smart remote monitoring?Yes. The 4YZPSJ-4C is equipped with an intelligent control system. After registering via the mobile phone APP, users can remotely monitor the vehicle's operating status, perform intelligent control, and conduct remote troubleshooting — greatly improving operational efficiency and reducing downtime.
-
QWhat measures are taken to prevent the engine from overheating during operation?The engine is equipped with an automatic and manual fan reversal function. When the water tank temperature reaches 92°C, the fan can automatically or manually reverse to blow back and clear corn husks that have accumulated on the water tank radiator, effectively preventing engine overheating and ensuring continuous, stable operation in dusty field environments.
