swingletree การใช้

• The term swingletree is sometimes used for draught whippletrees generally.
• The action of a swingletree is to balance the pull from alternate shoulders as the animal walks.
• For this reason heavier vehicles may have no swingletree, as they are normally pulled with a horse collar.
• The centre of the swingletree may be bolted directly to the body of the vehicle, this bolt pulling the vehicle along.
