Ballbarrow

The Ballbarrow was a variation of the wheelbarrow design,[1] by James Dyson released in 1974 in the UK.

Dyson said that the surface area of the ball, larger than that of a conventional design, made the ballbarrow easier to use in soft soil and more laterally stable with heavy loads on uneven ground.

[3] The original design featured a galvanised steel or copper hopper, forming integral rear legs.

Later the design was changed to a plastic hopper, with an optional clip on height-extension piece.

[5] Dyson continued with the ball-wheel concept in his design for the Trolleyball boat launcher in 1978, and the DC15 vacuum cleaner in 2005.
