Unexpectedly Intriguing!
13 August 2021

We've reached the dog days of summer, when the hot sun combines with thick humidity to make just being outside a miserable experience. It might be different if you were doing something fun, but no, you have grass to mow.

Meanwhile, your little one is over there, having fun, riding their tricycle. That's when a spark of genius arrives, unleashing the inspiration of innovation. What if you took their tricycle, attached a mower to the back of it, then made them mow the grass for you?

The Inventions in Everything team imagines something like that must have happened to lead to today's featured invention, the tricycle lawnmower. Or as it's properly identified in U.S. Patent No. 4,455,816, the Pedal Operated Mower. Here's Figure 1 from the patent - tell us what we just described is not how this invention was inspired!

U.S. Patent 4,455,816 Figure 1

The summary of the invention identifies physical fitness, injury avoidance, and environmental benefits, but does nothing to dispell our idea of how this invention came to be:

An object and advantage of the present invention is to provide a pedal operated mower that does not consume fuel or make noises corresponding to engines for mowers, but provides an arrangement that is conveniently an exercising assembly for operators, both young and old.

Another object and advantage of the present invention is to provide a man powered machine in which the operator need not be required to start an engine and to endanger pulling his arm out of socket in order to crank the mower, but the invention provides a tricycle frame and pedal operated mower arrangement so that a young person or an older person is capable of operating the assembly for purposes of conveniently cuttingthe grass while at the same time obtain exercise while grooming the yard.

We don't see many adult size tricycles like that presented in the invention's illustration available for sale in today's marketplace, so we can only assume the primary operators of the invention will be in the Age 4-6 demographic. To which we say to inventor Deanna Porath, well done!
