How wide do you have the track? I don't want to give my mare access to too much grass when they first go out but I need it wide enough so that she can roll. How wide will it need to be?
Mine is about 12 feet at the narrowest points wider near the gateways mainly because I am not the greatest with the tractor and roll/harrows! My brother decided the width really so that it is easy to get machinery round the track when necessary.
