Lying on your back with bits of rust, mud and oil falling on your face, while trying to undo the bolts, yes easy enough but can be frustrating. Just take care when you throw the spanners down to the bottom of your garden in frustration. Soak the nuts/bolts in WD40 first and ensure the correct fit of spanners. Some of the lock nuts will round off so have a supply of spares. Good luck...oh yes, Welcome to the nut house.
