It is suggested that you weld all the various components together when making the parlour, taking especial care that the reinforcing / earth under the cows feet is not pushed down too deep into the poured concrete ( needs to be about 1.0 to 1.5 inches max from the surface of the concrete). Often it has been found that their is a current "gap" between the collecting yard and the parlour. This can be overcome by grooving the collecting yard in a fan shape from the parlour and sinking a copper or other good conducter into the surface of the concrete ( again shallow ) and by connecting it up to the parlour earthing so creating a more gradual "current gradient" into the parlour. It can sometimes also be an issue at the parlour exit, causing cows to hang back / stop exiting and thus slowing up milking routines.<br />This has had a major impact in improving situations on some parlours over here and in Ireland.<br />Ian BrowneIan Brownenoreply@blogger.com
