I’ve been working on mowers for over 60 years and have never seen or heard of 3 wheeled Swisher push mower. Hope someone can help you out, as I’m never too old to learn something new.
Had a customer that had one. Vertical shaft Briggs engine, 2 large spoke rear wheels and a single wheel in the center front. Probably one of the easier pushing mowers around.
This is interesting, there was a three wheel and the drive wheel was in the back. I will try and find a picture from someone that may know in Warrenburg.
