The Benny Bulldozer Fun Bounce is a theme playground spring rider built for children 2 to 5 years of age. The bulldozer shape improves your child's understanding of a common piece of machinery. The fun bouncer is crafted to imitate a real dozer. The gears and scoop are crafted so your kids will make-believe they are plowing right through the playground. It is durable and will be able to withstand all of the elements Mother Nature can throw at it. The Benny Bulldozer Fun Bounce includes a heavy-duty coil spring with mounting plate. Mount the ride to concrete or in-ground with j-bolts or similar hardware.
