This lawn I do has a very steep hill and when I take my Scag 61" hydro WB down it to start going from side to side the engine spits and sputters. I guess I flooded it or something along the lines of that. I would go up and down but, there is a wood fence at the bottom and I'm afraid that it would act up again and I would go plowing right through the fence; Plus I'm not sure it would even make it. I am forced to use my 21" on this hill which is a pain. The mower has a 20 HP Kohler magnum engine. Can someone help me figure out whats wrong with this thing? If anybody could help me out I would Greatly appreciate it! Thanks!!!
