I am experiencing problems with my Lawnflite 940. The mowing deck became beyond repair, so I thought I would take the deck off and use it as a mini tractor, as the engine is in good condition. However, it is really difficult to engage Forward, Neutral & Reverse. I have to fiddle with the selector and at times have to shut the engine off before I can change FN&R. Also, not sure if it is connected to the above problem, but it drives fine on ground anything up to about a 30 deg slope, anything above there is a clunking sound coming from the rear end and I couldnt get it to move, nor engage neutral or reverse. The only why I could solve the problem was to raise the rear axle off the ground. Can anybody give me any advice as to what might be the problem. Thanks, Terry.
