We went from a manus abreast with very heavy claws into a gea herringbone with adf and they weighted our units up with 4 weights to match the manus ones but we took all the weights off before the first milking as it seemed stupid to have heavy claws increasing liner slip etc. Scc increased abit when we first went into the new parlour as stale cows didn't milk out properly but we just dried them off early. Mastitis rate dropped from 38% to 9% in the new parlourHow many weights do people have on there adf units? Or are they all the same
