Can anyone tell me if my Weibang Lawnmower is faulty. It is the first lawnmower i have owned and i have only used it a couple of times. The problems is with the gears and the self propelled function. I thought that having a self propelled lawn mower was supposed to make the job easier but it is making it more difficult to control the mower. It has seven gears and it does not matter what gear i use it takes of in front of me and is so hard to control that it feels like it is about to do a wheelie as it makes the front of the mower seem so light. It is actually easier to push manually than to us the self propelled function. Is this a fault with the mower or am i doing something wrong? Thanks
