A tensioner mechanism adapted for placing tension in a drive belt of a mower deck, the tensioner including an elongate member operatively coupled with an idler arm, and slidably mounted with a support member operatively carried by the mower deck. A compression spring carried on the elongate member between the idler arm and the support member operatively presses the idler arm away from the support member and is completely compressed during normal mowing operations for generally blocking the idler arm from swinging toward the support member during operation. A threaded member within which said elongate member is slidably received is adjustably fixed with the support member by a pair of nuts that can be adjusted on the threaded member to alter the position of the threaded member with respect to the mower deck for adjusting the tension that the idler pulley places in the belt during normal mowing operations. The position of an indicator adjacent to the threaded member serves to visually indicate to the operator that the tensioning mechanism has been properly adjusted to place the appropriate amount of tension in the belt.
Mécanisme de tension adapté pour appliquer une tension sur la courroie d'entraînement d'un châssis de tondeuse. Il comprend un élément allongé relié à un levier de direction et est monté de manière à glisser sur un élément d'appui porté par le châssis de la tondeuse. Une bague de compression, fixée sur l'élément allongé entre le levier de direction et l'élément d'appui, exerce une pression sur le bras de direction en direction opposée de l'élément d'appui et est complètement comprimée pendant que la tondeuse fonctionne normalement, pour empêcher le levier de direction de tourner en direction de l'élément d'appui pendant l'utilisation de la tondeuse. Un élément fileté, dans lequel ledit élément allongé est glissé, est fixé de façon réglable à l'élément d'appui au moyen de deux écrous pouvant être ajustés sur l'élément fileté pour en modifier la position par rapport au châssis de la tondeuse de manière à régler la tension exercée par la poulie de tension sur la courroie d'entraînement pendant que la tondeuse fonctionne normalement. Un indicateur placé à proximité de l'élément fileté indique à l'utilisateur que le mécanisme de tension est réglé de façon à appliquer la tension appropriée sur la courroie.
