Te Pari Drafting. With the two types of Te Pari Racewell selection boxes (Te Pari Racewell Sheep Auto Drafter) you can select up to 600 animals per hour. The criteria (weight, ear tag etc) for automatic selection can be set on the Te Pari T20 or T20E weighing indicator. Both selection boxes are robust and well tested in practice.
