"That is a Redneck Riding Lawnmower," said Wall.
In a garage beside Wall's neat white house on a quiet side street in Worthington, Wall likes to tinker.
In years past, he used to work uptown in the local hardware store, before it closed down, so his fix-it skills are well-known to many townspeople.
His garage door is usually open when the weather's warm and passers-by glance in to see him hard at work on some project -- unless he's standing out front talking to friends or family that notice the open door and frequently pull over to chat.
The Redneck Riding Lawnmower took shape in Wall's garage after he got the idea from a picture and looked at a plan to build one.
"I saw a picture of one a few years back and so this year, I made one," said Wall.
The front end is a recycled reel-type grass cutter. It's powered by a coaster-brake-style old-fashioned bicycle.
It's a people-powered machine that doesn't use gas and doesn't make much noise.
In theory, one could use the lawnmower to pedal through the task of mowing the yard.
In reality, Wall confesses he uses a more modern lawnmower to take care of his own large yard.
But his Redneck Riding Lawnmower does work -- Wall's hands-on demonstration proved his creation does cut grass.
In this day of high gas prices and hard times, and all the talk about "going green," might Wall start selling these lawnmowers?
"Oh, I'd sell it if somebody wanted it," said Wall. "I'd sell about anything around here."
Wall knows his lawnmower does attract attention, but he doesn't think too many people would want to buy them to use on their yard.
However, in a corner of his garage, a couple of old bicycles and another rusty reel-type grass cutter are tucked away just waiting to be transformed into another Redneck Riding Lawnmower.
