Abstract
Description
また、このように構成された本発明によれば、芝刈り機を前進させながら芝を刈るときに、後列を構成するヘッドの刈り終わり位置を、前列を構成するヘッドの刈り終わり位置と揃えることができる。これにより、複数のヘッドが前後方向に分けて配置された芝刈り機において、使用者が芝を刈りたい領域(例えば、フェアウェイ領域)と、芝を刈りたくない領域(例えば、ラフ領域)との境目をより確実に区別して刈り込むことができる。

Claims (5)
- リール型の刈り刃と、刈り刃と近接して設けられた固定刃とを有するヘッドを複数個備える芝刈り機であって、
複数個の前記ヘッドは、各々の前記ヘッドによって芝を刈り取れる範囲が部分的に重複するように、前記芝刈り機の前方に配列された前列と、前記芝刈り機の後方に配列された後列との二列に分けて配置されており、
前記芝刈り機は、さらに、前記刈り刃を水平軸周りに回転させるための出力を提供する流体装置と、
前記流体装置を制御するための流体制御装置とを、備え、
前記流体制御装置は、前記刈り刃の回転時には、前記流体装置内の流体流れを制御して前記刈り刃を回転させ、前記刈り刃を停止させる際には、前記流体装置内の流体流れを逆転させ、
前記流体制御装置は、前記後列を構成するヘッドによる刈り終わり位置と、前記前列を構成するヘッドによる刈り終わり位置とが揃うように、前記後列を構成するヘッドを、前記前列を構成するヘッドよりも所定時間だけ遅れて芝を刈り終えるように制御する、ことを特徴とする芝刈り機。 - 前記後列を構成するヘッドは、前記前列を構成するヘッドよりも所定時間だけ遅れて芝を刈り始めるように制御される、請求項1に記載の芝刈り機。
- 前記所定時間は、前記前列を構成するヘッドの刈り刃と前記後列を構成するヘッドの刈り刃との間の距離を前記芝刈り機が移動するのにかかる時間である、請求項2に記載の芝刈り機。
- 前記前列を構成するヘッドの始動時には、前記後列を構成するヘッドを上昇させておき、前記前列を構成するヘッドの始動後、所定時間経過したときに前記後列を構成するヘッドを降下させることにより、前記後列を構成するヘッドの刈り始めを遅らせる、請求項2又は3に記載の芝刈り機。
- 前記前列を構成するヘッドを停止させた際に、前記前列を構成するヘッドを上昇させ、前記前列を構成するヘッドの停止後、所定時間経過したときに前記後列を構成するヘッドを上昇させる、請求項1乃至4の何れか1項に記載の芝刈り機。
