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”
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.

1. A turf maintenance vehicle comprising: a chassis comprising a front end and a rear end, the rear end spaced-apart from the front end along a longitudinal axis of the vehicle;a support platform retained by the chassis, the support platform comprising a footrest portion and a floor portion located
1. A turf maintenance vehicle comprising: a chassis comprising a front end and a rear end, the rear end spaced-apart from the front end along a longitudinal axis of the vehicle;a support platform retained by the chassis, the support platform comprising a footrest portion and a floor portion located aft of the footrest portion, wherein either the chassis or the floor portion comprises a tab protruding from the chassis or the floor portion, respectively, and the other of the chassis or the floor portion defines an opening adapted to receive therein the tab when the support platform is joined to the chassis, wherein the tab defines, in cross section, a Z-shaped member, wherein a first tab portion of the Z-shaped member is positioned above a first surface of the chassis and a second tab portion of the Z-shaped member is positioned below a second surface of the chassis when the tab is received in the opening;elastomeric first and second forward isolators positioned between the chassis and the support platform at or near the footrest portion; andan elastomeric rear isolator also positioned between the chassis and the support platform at or near the floor portion, the rear isolator comprising a grommet positioned along a periphery of the opening. 2. The vehicle of claim 1, wherein the forward and rear isolators are adapted to: locate the support platform, relative to the chassis, along longitudinal, transverse, and vertical directions; andattenuate vibration transmitted from the chassis to the support platform. 3. The vehicle of claim 1, wherein the opening is formed in a chassis plate of the chassis, the chassis plate parallel to the floor portion of the support platform. 4. The vehicle of claim 1, wherein the first and second tab portions of the Z-shaped member are parallel to each other. 5. The vehicle of claim 1, wherein the second tab portion of the Z-shaped member extends from an intermediate tab portion towards the rear end of the chassis when the tab is received within the opening. 6. The vehicle of claim 1, wherein the first and second forward isolators each comprise a frustoconical surface. 7. The vehicle of claim 1, wherein each of the first and second forward isolators is positioned near a forwardmost end of the footrest portion of the support platform when the support platform is joined to the chassis and in a normal operating position. 8. The vehicle of claim 1, wherein the rear isolator is positioned near a rearmost end of the floor portion of the support platform when the support platform is joined to the chassis. 9. The vehicle of claim 1, further comprising a second, elastomeric rear isolator positioned between the chassis and the support platform at or near the floor portion.
