Paul, the only one I have used was a 550 non self propelled and that was heavy to use, I can't understand why they made that model. I have a self propelled F/C here but I have only got the motor running, the cable to the gearbox has been disconnected and that required removing the box to re connect it and that was going to take time I didn't have to get it sorted so I can't comment on how well they work. The 24's big rear wheels are a big advantage, problem with the new ones fitted with a Honda motor are I believe around the $1800 mark. I have watched my grandson using his F/C 24 on 45 degree slopes that I could hardly walk on. He and another mate of mine use theirs regularly in their lawn mowing businesses
