As your work and hobbies change, so can Ursa. One look at the Ursa system and accessories will show you how Ursa grows with your needs. Ursa accessories are engineered specifically for the Ursa's unique design. So you know your Ursa will continue to perform with single-handed ease, even as you discover new ways to use it. Clevis Hitch Quickly (without tools) connects any Ursa Wagon frame or Cargo Sled to a lawn tractor or all-terrain vehicle (ATV). The Clevis Hitch can be left in handle with the foam grip so that it's always ready when you are. Trailering Arm This zinc-plated steel 18" arm shortens the standard arm for a tighter towing distance. Includes a standard 1/2" hitch pin that fits most applications. Pro Wings The Pro Wings give you the versatility you need to do the job right. The patented design encloses, heightens, or widens any Ursa Cargo Sled. Optional wing end panels (shown in photo at left) available. See details. Pro Wing End Panels These durable all-weather fabric panels connect the wing edges in the open vertical position, stabilizing Ursa's expanded cargo space and providing handy storage pockets for tools and wagon accessories. Pro Cargo Sled Interchanges with the Ursa Flatbed's platform. Or use as a stand-alone heavy-duty sled. Includes handle and mounting hardware. Ships in one box with easy-to-follow assembly directions. Tows by snowmobile with optional clevis hitch. Pro Flatbed Top Interchanges with the Pro Turf or Pro Field 4S Wagon's cargo sled. Large and stable, the Pro Flatbed Top carries bulky items, even mounted equipment, and tilts just like its sister Pro Cargo Sled to help you unload. What's more, the platform is made of recycled plastic, so it's sliver-free, rot-free, and eco-friendly to boot. Pro Flatbed Subframe Top this subframe with the material of your choice to build a custom platform. The aluminum subframe includes brackets to attach the platform to the Pro Wagon chassis. Pro Saddle Rack Perfect for moving saddles from the trailer or tack room to the arena, this saddle rack slides onto clips mounted in the Wagon's dump box. Two racks can fit per Wagon.

Pro Toolholder This durable all-weather-fabric Pro Toolholder mounts to the side of the Pro Cargo Sled and provides a handy place for Ursa accessories, components and tools. Chocks Heavy-duty yet lightweight chocks stabilize the Ursa Wagon wheels and are especially useful when working with heavy loads or on uneven terrain. Sold in pairs.
