(1)拖拉机配上背负式联合收割机,质心高度显著提高,在道路较窄的情况下跑偏,极易翻车。而且,由于在割台和脱粒装置之间有一个长长的输送槽,使得在翻车时驾驶员很难跳车。因此,驾驶员首先要摸清收割机行走路线上的道路情况,在道路较窄的地方应预作处理,不要冒险行驶。 (2)割台本来就是一个容易损坏的部件,工作和转移时极易碰坏,而背负式联合收割机的割台提 (1) Tractor coupled with knapsack combine harvester, the centroid height significantly increased, in the case of narrow road deviation, easily overturned. Furthermore, due to the long trough between the header and the threshing device, it is difficult for the driver to jump in during rollover. Therefore, the driver must first find out the road harvester walking routes in the narrow roads should be pre-treatment, not to take risks. (2) The header is an easily damaged part that can be easily damaged during work and transfer, while the header on a piggyback combine harvester
