Make sure that the clamp is slightly domed and has been well sheeted in the normal way. Secure Covers should then be fitted across the clamp starting at the back and working forward, so that they can be rolled back as the clamp is fed.
Keep the Secure Cover smooth and stretched tight using suitable weights around the edge and across joins. As the silage settles ensure the Secure Cover remains taut.
Replace tyres entirely. The filled bags fits into the shoulders of the clamp providing a very effective seal. When filled each 1m long bag weighs between 15-20kg.
