From the side 5

  1. Ramp The horse walks up it into the trailer. With only a rear ramp, the horse has to back out again.
  2. Vents They let air through while the horses travel. Some trailers have more vents along the side panels.
  3. Coupler It fits over the tow vehicle's hitch ball and locks on.
  4. Tongue jack It holds the front of the trailer up when it is unhitched. It is wound right up before towing.
  5. Safety chains They hook to the tow vehicle. That is in case the trailer comes loose from the hitch.

Inside, from above 7

  1. Stalls This trailer has two, side by side. The horse stands facing the front.
  2. Divider It keeps the two horses apart. Stall dividers are locked in place before the trailer is towed.
  3. Chest bars The horse stands with its chest behind it. It is padded.
  4. Butt bars It is fastened behind the horse, before the horse's head is tied. Some trailers have a chain or strap instead.
  5. Mats Rubber mats give the horse grip and some cushioning. They are lifted so the floor under them can be cleaned and dried.
  6. Floor It is drawn here as boards. It is checked regularly, and any weak board is replaced.
  7. Tie rings The horse's lead rope is tied to it. The knot or snap is one that lets go quickly.

How it works

The parts of a horse trailer are those of any trailer on the outside. Inside it is fitted out to keep each horse standing safely in its own stall.

From the side

At the front are the coupler, the safety chains and the tongue jack. Vents sit on the roof. At the back the ramp is let down for loading.

Inside, from above

The floor is boards. Two stalls lie side by side with a divider between them. Each stall has a chest bar across the front and a butt bar across the back, and a tie ring on the front wall. One stall has a mat on its floor, and the other has a horse drawn in dashes, facing forward.

  • This page names the parts. It does not teach loading or towing.
  • Many trailers have no ramp, and many carry their horses at a slant.
