Abstract
(EN)
[Problem] To provide an electric work machine capable of preventing erroneous operation even if the key switch has been set to the ON state before drive or other preparations are complete. Lever sensors (23, 24) are provided which detect the operation position of pivoted levers (21, 22), and a control device (50) is provided which energizes the electrical path (32b) between a battery (31) and travel unit motors (15, 16) after detecting the neutral position of the pivoted levers (21, 22). Further, this lawnmower work machine (1), which is an electric passenger vehicle, is provided with a sitting sensor (33) for detecting sitting in a seat (5), and the condition of detecting sitting in the seat (5) is added to the conditions under which the electric path (32b) between the battery (31) and the travel unit motors (15, 16) and the operation unit motors (28, 29) is energized.

L'invention a pour but de proposer une machine de travail électrique apte à éviter un fonctionnement erroné même si le commutateur de la clé a été mis sur l'état MARCHE avant que les préparations à la conduite ou autres préparations n'aient été exécutées. Des détecteurs à levier (23, 24) sont utilisés pour détecter la position de manœuvre de leviers montés pivotants (21, 22), et un dispositif de commande (58) met en circuit le trajet électrique (32b) entre une batterie (31) et des moteurs unitaires de marche (15, 16), après la détection de la position neutre des leviers montés pivotants (21, 22). En outre, cette machine de travail de tondeuse à gazon (1), qui est un véhicule électrique autoporté, est munie d'un détecteur d'assise (33) destiné à détecter le fait que quelqu'un soit assis sur un siège (5), et l'état de détection de l'assise dans le siège (5) est ajouté aux conditions sous lesquelles le trajet électrique (32b) entre la batterie (31) et les moteurs unitaires de marche (15, 16) et les moteurs de l'unité de commande (28, 29) est fermé.
