4UX-120 Potato Harvester is a new potato harvesting facility. This equipment can better adapt to the requirements of potato planting agronomic and growth characteristics in China. It can realize the functions of excavation, soil removal and laying. The whole process is smooth and the single ridge double ridge or single ridge single crop can be harvested. This machine is used for potato harvest, can greatly reduce the human demand, reduce the shortage of rural labor, reduce the cost of harvest operations.

The main features of the machine:
1) High harvest efficiency, low breakage rate, low breaking rate 
2) Using the excavation device into the angle and transport separation device litigation angle consistent with the design, an effective solution to the problem after the shovel;
3) Using overload protection, effective protection equipment; 
 

The machine is attached to the tractor
1. Adjust the tractor back to the middle of the potato harvester to raise the tractor down lever to the appropriate height and reverse it to the left and right hooks of the potato harvester.
2. After the harvester is installed, the tractor lifts the harvester to adjust the length of the tractor left and right, so that the harvester reaches the left and right levels. At the same time with the universal joint to the tractor after the output shaft and the harvester's power input shaft connection. Hand section of the universal joint, check whether the card, touch the phenomenon. If so, should be promptly excluded. The tractor's power output shaft speed adjusted to 540r / min, ready to work.
3. The operation of the tractor is operated according to the instructions of the tractor.
 

Operation and use
1. According to the need to adjust the vibration size, will support the rubber tire bolts, rubber wheel up, vibration becomes smaller, rubber tire down, vibration becomes larger.
2. Chain drive device with overload protection, when the harvester overload, the main passive side of the friction between the slip, to protect the machine parts from damage. The overload torque can be adjusted by adjusting the nut. When the nut is rotated counterclockwise, the overload torque becomes smaller and the overload torque becomes larger when clockwise is rotated. Note that the adjustment of the three bolts should be consistent.
3. Adjust the tractor's three-point suspension and limit the height of the wheel, and its lock, so that digging shovel excavation depth of 20 to 30 cm.
