A support platform isolator system for a turf maintenance vehicle. The isolator system may include one or more rear isolators, and one or more forward isolators, the isolators positioned between a chassis of the vehicle and a support platform. The isolator system may not only reduce “metal-on-metal” noise between the chassis and the platform, but may also attenuate vibration and/or shock loads transmitted to the platform. In addition, the system may assist in locating the platform on, and retaining the platform to, the chassis. The isolators of the system may form primary contact areas between the chassis and the platform.
