Though this technical scheme can once complete rotary tillage, ridging operation, and finish fertilization work in the process of rotary tillage, ridging. However, this rotary tiller does not have the functions of harvesting and ditching. When harvesting and ditching, it is necessary to repurchase or manufacture corresponding equipment, thereby increasing the input of farming costs. At the same time, when working, it is necessary to manually operate the ridge-supporting device, and the manual standing operation is time-consuming and laborious.

The power rotation torque is transmitted to the walking wheels after being decelerated by the walking gearbox. The front, rear, left, and right sides of the rotary tiller are respectively equipped with driving half shafts and walking wheels to form a four-wheel drive. The walking wheels are composed of blades, rims, hubs, rubber When working in paddy fields, the blades of the walking wheel play the role of loosening and crushing the soil while walking to make slurry. Replace the ditching knife or ridging knife to perform ditching or ridging, rotary tillage, rolling Plowing, ditching, and ridging are integrated to perform dry farming and hydroponics. But this rotary cultivator can't realize harvesting function, adopts four-wheel walking ability to be poor simultaneously, and the passing ability is not good under the poor situation of soil condition.

To sum up, the existing rotary tillers have a single function, and each has different functions and application ranges, but they cannot realize harvesting, rotary tillage, ditching, ridging and underground harvesting as a whole, and their running ability is poor.
