If the two large tires can fit on the rack......the rear tire only needs support. The rear tire sits in a bracket by turning is sideways. There is a rear steel bar that goes behind the two large tires that locks the machine in place.
Will get pictures up soon.
But yes.....the Ecolawn is very light....which makes moving it super easy! I'm sure you could modify your PG Rack to fit a Ecolawn.
