I have an older type Murray with 17 hp motor and I think the model # is 46569x92a dont know for sure as the number has rusted off the body . It will run ok on the level but will not pull up a slight incline . I have put a new drive belt on it and tried adjusting the clutch rod , all to no avail . Does the transmission have a replaceable clutch plate and if so how do you change it .:banghead3 :banghead3 :banghead3
