To provide a grass mower capable of advancing in a travelling direction without deviating from a predetermined travelling passage, a grass mowing system, and a drive control method of a grass mower.SOLUTION: A grass mower 10 includes drive parts 14R and 14L provided on right and left sides respectively, which are driven separately, an inclination estimation part for estimating an inclination in a slope of a travelling passage, and a drive control part for driving the right and left drive parts 14R and 14L with different drive force so that the grass mower does not slip down the slope when the grass mower advances in a direction crossing the slope according to the inclination estimated by the inclination estimation part. Therefore, even if there is an inclination on a travelling passage of the grass mower 10, an advancing direction of the grass mower 10 is corrected by the drive parts 14R and 14L being driven with different drive force according to the inclination when the grass mower advances in a direction crossing the slope. Thus, the grass mower 10 is prevented from slipping down to the lower side of the slope, thereby causing the grass mower 10 to advance in a travelling direction without deviating from a predetermined travelling passage.SELECTED DRAWING: Figure 8

    【課題】予め定められた走行路から外れることなく進行方向に進むことができる草刈り機、草刈りシステム、及び草刈り機の駆動制御方法を得る。【解決手段】草刈り機10は、左右両側にそれぞれ設けられ各々別駆動される駆動部14L、14Rと、走行路の斜面における勾配を推定する勾配推定部と、勾配推定部により推定された勾配に応じて斜面を横切る方向に進行する際に斜面においてずり落ちないように左右の駆動部14L、14Rを異なる駆動力で駆動させる駆動制御部と、を含む。従って、草刈り機10の走行路に勾配があっても、斜面を横切る方向に進行する際には、勾配に応じて駆動部14L、14Rが異なる駆動力で駆動することにより草刈り機10の進行方向が修正される。これにより、斜面において草刈り機10が斜面下にずり落ちるのを防止することができるので、草刈り機10を予め定められた走行路から外れることなく進行方向に進ませることができる。【選択図】図8
