随着耕作制度的改革,少耕法的试验和推广,愈来愈迫切地需要具有高效率、高效益的定型少耕机具来适应生产的新发展。我场新近采用的佳木斯第二农业机械厂制造的牵引式1 BJ—4.4四十片中型圆盘耙,不仅具有液压操作、运输方便、保养维护简便等优点,而且经试验使用表明是适应少耕作业的农艺要求的。该机可与东方红—75拖拉机配套,用于麦茬、豆茬等耙茬整地的效果良好。现将该机的性能和结构特点及试验使用
With the reform of the tillage system and the experiment and promotion of the less tillage method, there is an ever-increasing need for a set of less tillage machines with high efficiency and high efficiency to adapt to the new development of production. The newly adopted 40 Class 1 BJ-4.4 medium-sized disc harrow manufactured by Jiamusi Second Agricultural Machinery Factory in our field not only has the advantages of hydraulic operation, convenient transportation and convenient maintenance and maintenance, but also has been proved to be suitable for less tillage Agro-industry requirements. This machine can be matched with Dongfanghong -75 tractor, which has good effect on wheat stubble, stubble and other stubble land preparation. Now the aircraft performance and structural characteristics and test use
