a mechanism for suspending a mower deck from a vehicle , including a suspension member having a longitudinally extending axis and a laterally extending portion which supports the deck at a plurality of spaced locations . a structural member fixed with the vehicle includes an opening within which the suspension member is positioned . a position retainer is coupled with the suspension member and abuts the structural member for blocking the suspension member from shifting along its longitudinal axis out of the opening . engagement of the suspension member within the opening of the structural member is the sole location at which the suspension member is connected to the vehicle . a removable blocking member is positioned adjacent the opening for generally blocking the suspension member from shifting laterally with respect to its axis and out of the opening . the opening is defined in a surface oriented generally perpendicular to the axis of the suspension member .
