Abstract
(EN)
Provided is a technology of reliably preventing a work machine from operating when an engine starts. In this tractor, a lifting/lowering valve of a hydraulic lifting/lowering system of a work machine is mechanically connected to a lifting/lowering lever. An engine start condition in the tractor is that a reverser lever is neutral, a PTO clutch is off, a seat switch is on, and the lifting/lowering lever is at the lowest position. A switch driving unit is provided on a side surface orthogonal to the turning direction of the lifting/lowering lever, and a switch is provided at a position so as to face the switch driving unit when the lifting/lowering lever is turned to the lowest position, so that the lifting/lowering lever at the lowest position is detected by the switch.

La présente invention concerne une technologie permettant d'empêcher de manière fiable une machine de travail de fonctionner lorsqu'un moteur démarre. Dans ce tracteur, une soupape de levage/abaissement d'un système de levage/abaissement hydraulique d'une machine de travail est reliée mécaniquement à un levier de levage/abaissement. Le moteur du tracteur est démarré à condition qu'un levier d'inversion est en position neutre, qu'un embrayage de prise de force est éteint, qu'un commutateur de siège est activé, et que le levier de levage/abaissement est dans la position la plus basse. Une unité d'entraînement de commutateur est disposée sur une surface latérale perpendiculaire à la direction de rotation du levier de levage/abaissement, et un commutateur est disposé en une position de manière à faire face à l'unité d'entraînement de commutateur lorsque le levier de levage/abaissement est tourné vers la position la plus basse, de telle sorte que le levier de levage/abaissement au niveau de la position la plus basse est détecté par le commutateur.

エンジンを始動する際に作業機の作動を確実に防止する技術を提供する。作業機の昇降油圧システムの昇降バルブと、昇降レバーとが機械的に連結されるトラクタにおいて、リバーサレバーが中立であり、PTOクラッチが切であり、シートスイッチがオンであり、かつ、昇降レバーが最下げ位置にあることをエンジン始動の条件とした。前記昇降レバーの回動方向と直交する側面にスイッチ駆動部を設け、前記昇降レバーが最下げ位置まで回動されたときに前記スイッチ駆動部と対向する位置にスイッチを設け、前記スイッチによって、前記昇降レバーが最下げ位置にあることを検出する。
