As a farming tool, 1LYQ-320 type walking circle tray plough with two trays is fit to 6-12 horsepower walking tractors, it may be used to turn up the soil, either in water or not. Because the circle tray turns up the soil rolled, the stems and straws are cut up and thrown down the gully. The plough is more suitable to the farm with many straws and the stems high and the stems returned to the field, it is not easy to be stopped up and pulled, the soil. With the turning up the soil rolled, the frictional force is lower, the depleted efficacy is lower, so its efficacy is higher and the depleted oil is less than the plough share.
