小麦联合收割机前进速度的选择主要应考虑小麦的产量、小麦的自然高度、小麦的干湿程度、作业地点的地面情况、发动机的负荷及驾驶员自身的技术水平等因素。但无论是悬挂式还是自走式小麦联合收割机,作业时的喂入量都是决定联合收割机前进速度的关键因素。联合收割机作业时前进速度的选择不能单纯以小麦产量为依据,还应考虑小麦切割高度、地面平坦程度等因素。一般小麦亩产量在300～400千克时可 Wheat combine harvester forward speed of the main choice should consider the wheat yield, the natural height of wheat, the degree of dry and wet wheat, the job site ground conditions, the engine load and the driver’s own technical level and other factors. However, whether it is hanging or self-propelled wheat combine harvester, the amount of feed during operation is the key factor that determines the speed of the combine harvester. Combine harvester operating forward speed selection can not simply based on wheat yield, but also should consider the wheat cutting height, the ground level and other factors. General wheat mu yield 300 to 400 kg can be
