Hello, been browsing around forums for a while now and finally have something to post. Purchased 25 high impact plastic wheels with sealed bearings a while back. Question is do i let it ride on the ground or about a inch off the ground? It will be pulled behind a ztr. Plan on having it to where it will flip up and mount behind seat when not in use. And when in use need to know a height for the wheels. Any oppinions would be great.
