| Abstract: | According to the demand of developing a permanent raised beds （PRB） wheat planter, a combined press device is developed to press ridge sides and planting zones at the same time. Compacting wheels are designed to compact the ridge sides to ensure the reshaping effect, while press roller Ⅰ and press roller Ⅱ are designed to press the planting zones. Two tubes are used to make the maize stubbles pass unobstructed. In field trials it is proved that the press effect of the combined press can satisfy the agricultural requirements. |
