Description
本発明による作業車の実施形態の一例を説明する。本明細書では、特に断りがない限り、「前」は車体前後方向(走行方向)に関して前方を意味し、「後」は車体前後方向(走行方向)に関して後方を意味する。また、左右方向または横方向は、車体前後方向に直交する車体横断方向(車体幅方向)を意味する。「上」または「下」は、車体の鉛直方向(垂直方向)での位置関係であり、地上高さにおける関係を示す。
図3,図4を用いて、操舵レバー18の位置検出構成と、操舵レバー18による走行制御構成について説明する。
(1)電動草刈機は、さらに警報装置37を備えても良い。操舵レバー18が停車位置に操作されたことを制動用位置センサーが32検知している際に、ニュートラル位置以外に操舵レバー18が位置することを走行用位置センサー30が検出すると、制動制御部35は警報装置37を作動させ、警報を発して警告を行う。
