Anti-Backer Four Arm - Pair
Anti-Backer is an easy solution based on a simple yet operational design; angled arms on the unit involve the sheep moving forward but once past the arm the sheep can no longer move backwards. This incredibly easy but pertinent solution is so effective as you can use multiple Anti-Backer units to line a whole race so your sheep are always moving in the direction you want.
Anti-Backer is an incredibly efficient and super easy way to keep you sheep moving forwards and not backing up.
This is for two x Anti-Backers.
