A novel method was introduced based on a type of profiling elastic press roller to solve the problem that soil compaction pressure is difficult to monitor in real time. The pressure real-time values were acquired through the measurement of the profiling elastic press roller’s eccentricity. In order to evaluate the relationship between the profiling elastic press roller’s eccentricity and the pressure,...
According to the characteristics of double row ridge cultivation technique, the profiling elastic press roller (PEPR) was designed. In order to further understand the performance of the PEPR, field experiments were conducted to investigate the effects of press roller types and forward velocity levels on seedbed properties and soybean emergence. The three kinds of press rollers were: conventional press...
