A mechanism for absorbing impacts encountered by a mower deck coupled with a vehicle, including an arm operatively coupled with the vehicle, a longitudinally extending first tube member coupled with the arm and defining a generally linear axis which extends rearwardly and inwardly toward the vehicle, a second tube member operatively coupled with the mower deck, the first tube being slideably received within the second tube for allowing the second tube to shift linearly along the axis as the mower deck encounters frontal impact loads, a compression spring positioned within the tubes for biasing the second tube and mower deck forwardly with respect to the first tube, and the second tube member is allowed to pivot with respect to the first tube member for allowing the mower deck to pivot from side to side to follow undulating ground contours. |
