    • A method of transferring weight between a tractor and an agricultural toolbar is provided. The method comprises determining a net toolbar ground force acting on a plurality of toolbar wheels supporting a toolbar. The method further comprises determining an estimated tractor weight carried by the rear tractor wheels of a tractor based on a user input. The method also comprises determining an estimated tractor weight transfer amount transferred between said tractor and said toolbar based on a pressure in an actuator configured to transfer weight between said tractor and said toolbar. A further step is provided of calculating a net tractor ground force by adding said tractor weight transfer amount to said estimated tractor weight. The method further comprises comparing said net tractor ground force to said net toolbar ground force. A further step of modifying a pressure in said actuator so that said net toolbar ground force more closely approximates said net tractor ground force is provided.
    • 提供了在拖拉机和农业工具栏之间传递重量的方法。 该方法包括确定作用于支撑工具栏的多个工具栏轮上的净工具栏地面力。 该方法进一步包括基于用户输入来确定拖拉机的后拖拉机轮所携带的估计拖拉机重量。 该方法还包括基于配置成在所述拖拉机和所述工具栏之间转移重量的致动器中的压力来确定在所述拖拉机和所述工具栏之间转移的估计的拖拉机重量转移量。 通过将所述拖拉机重量转移量加到所述估算的拖拉机重量来计算净拖拉机地面力的步骤。 该方法还包括将所述净拖拉机地面力与所述净工具栏地面力进行比较。 提供了修改所述致动器中的压力以使所述净工具栏地面力更接近所述净拖拉机地面力的另一步骤。
