My guess is that it was built for bird hunting as 2 shooters would sit on the front. Not saying that's a smart thing... just a guess.
I would be interested in knowing what the purpose behind that was? I know of an Asparagus Farmer who modified a Snapper mower, so he could drive between the rows and harvest spears w/o getting off the machine in Brooklyn,Iowa.
When I worked for Farmhand, inc. We had a Tricycle machine called a FarmHandy(built in Greely,Co) with side by side seating. I was told it was used out west in sugar beet fields. Two men rode on it with weed hooks and cut weeds out of the rows.
