We all need a better spreader cover--for hand spreaders as well as ride-ons. I wish there was a better cover; one that was easy to get off--one that was hinged, yet fully waterproof, and easy to open with one hand. (A hand that was wearing a glove.) It needs to be transparent to view the remaining product, if possible. And easy to fill from a 50 pound bag. If it did not get stiff in cold weather--that would help. Anybody seen a good one?
