Went to carlise in early 80's north country cheviots in April hogs making 60 pounds plus sub on them this was just before easter vevers was buying a lot then. If you times up the value to now what would be the price today ?
Just get a pice of pipe about 7 feet long weld a lug on end and Sharpe up cuts bags a treat and no going under bags with a knife for safety's sake do that .if you use a pice of stainless steel to sharpen keeps sharper longer.
Do an experiment yourself only thing you need to do is walk a line yourself in a field with no cattle in it and the grass will nt grow the same it has to be a regular walk not just a one of in the same line cattle walk a lot over a field when grazing.
One idea is to make the standing area lower than the feed area if you put digonal bars in lean them away from the cows so they don't rub the shoulders if you put diagonal barriers in just go as high as you can as high as the cows so top bar does not rub on the cow neck shoulder..
