Motorized wheelbarrows have been around for years, but the uninitiated might want to check out the Honda HP450 and its 163cc, 5.5hp 3-stroke engine. It can haul nearly 1000 pounds on level ground.
It can also haul over 550 pounds up a 25-degree incline, so it's not bad on slope either. Plus, the entire load can be dumped easily using the controls. Not a bad idea if you have some projects that involve heaving lifting—and the $4000 price tag beats the hell out of a hernia. [Honda via TRFJ]
