Abstract
A pivotally mounted hood for a tractor is disclosed wherein a gas spring, provided to offset the weight of the hood to facilitate the movement of the hood between opened and closed positions, is mounted to the chassis via a multi-position bracket having more than one hole therein for the selective connection of the gas spring. The bracket holes are arranged in a configuration defining a progressively increasing distance from the pivot connecting the hood to the chassis, thereby providing alternative mounting positions for the gas spring which have different moment arms for the application of the force exerted by the gas spring about the hood pivot. The gas spring can be remounted to a hole providing a larger moment arm relative to the hood pivot as the gas spring weakens over time due to the loss of gas therefrom, which enables the effective spring force offsetting at least a portion of the weight of the hood to remain substantially constant even though the gas spring weakens.
