I have a 6 year old Craftsman Lawn tractor Model number 917.273750 I mowed the lawn without problem a day ago but when I came to move it again it will not drive forward or reverse The drive belt feels very loose (should it be?) and I have a nasty habit of changing the gear without using the clutch ( zips on flameproof suit) Ideas please
Oh when I use the clutch at startup having selected a gear it 'grabs' , the front of the tractor rears up like it was sharply engaged
