Will this product fit on a 3/4 inch riding lawnmower axle and will craftsman gt 3000 rear wheels fit?
This hub features a 1" inner (or inboard) shaft diameter with the axle turned down to a 3/4" outer diameter so it may work with your 3/4" axle. We are unable to advise on compatibility with Craftsman GT 3000 rear wheels unfortunately, we'd recommend performing further independent research and/or comparing the images & specifications of this hub to what you need.
