From my childhood...picture a snowblower without the rotary blades, chute, and hood over the blades. That's what Granddad had along with various garden attachments such as a tiller, spring tooth, disc, and sickle mower.
Well, without ANY of the attachments the old 5 or 6 hp Briggs & Stratton on those two mini-tractor tires and frame would pull a little red wagon with me in it ALL OVER town in the summer time. I was 10 to 11 years old. Even had a classmate who's dad had a very similar unit.
We tooled up and down the streets in our little, rural Iowa farming community, racing each other and being general nuisances but enjoying every second of it.
Every time I fire up my 9.5hp snowblower, now, at 61y.o., I think what fun it would be to rip the rotary plow off the front, get a Red Flyer wagon and drive around town. They'd probably lock me up for being crazy. But that's what I want to do.
eta: Scout (poster above me) included a video of what I'm talking about...but I was already out of high school when that 1974 unit was new. Granddad's 'power head' (good descriptor) was more likely 1940's or 50's vintage. Picture that without the tiller and your red wagon tied or wired to the chassis somewhere underneath. I know, I know...nobody cares but this is triggering some great memories here. Bear with me.
