I second murphy 1244. The bucket needs to be much flatter to get a good finish. If you have double action lift rams this is easy. If you have single action lift rams then you need to get some ballast in the bucket (not so much it falls out) . I used to drive an mf240 fel and back blade on foot path ,and car park and sand pad (foundations) work . That tractor had a change over valve to operate the 3ph OR the fel.
