The stones in the farmland have a great influence on the farmland's farming income, and also have great damage to mechanized sowing and receiving equipment. 

In order to solve the problem about difficult to clean the stones in the land, and control the cost of cleaning, our company has developed a new type stone cleaner.

The stone cleaner is motivated by tractor, there is a three-point suspension which has been connected to the stone cleaner. The stone cleaner will be dragged to move forward as the tractor move forward, meanwhile the digging knife will go deep into the soil to collect and transport stones and soil to the front chain, then those stones and soil will be sent to the rear rotating screen to separate the soil and stone. The stones will be transfer into the paralleled tractor bucket by belt conveyor. Stones will be carried away when the bucked is full. Generally, one main stone cleaner is equipped with at least two stone-carrying tractors which could transfer in turn.

The stone cleaner can also be used for cleaning potatoes, sweet potatoes and other bulk crops.
