okay,...but for pulling, it seems to me that it would be a simple matter to attach a chain to the drawbar mount under the differential with a heavy duty clevis.
Possible for a short pull like you were doing pulling a bush out. But if you try to make a turn with a chain secured under the tractor, it will get pulled into the tires where the traction bars will grab it and wrapp ytou all up in it. Bad ju ju!
