First of all you have to check the breast collar which is attached and hanged to the saddle. You have to maintain safety by not ducking under the horse neck. It is better for you to go around and do your job. Keep your head away from the horse head while attaching a collar. Ask your handler to hold the horse for you. Now pick your breast collar up and reach around the horse. Don't duck under the horse head, but bring the collar belt to your side and then attach it to the ring on the saddle. Now again avoid your head under your horse. You have to bring the strap that goes between the legs and bring it through and then attach to the connector. Do not place your knees on the ground. Now insert your fist under the breast collar fit. Your fist must go in easily without being too loose. If you are not able to insert your fist then you have to loosen it. Also the adjustment on the left side as shown should be similar to the one on the right side. Make sure that you have tightened the belts in the same holes on either side of the horse.You need to use Back Cinch when you have to go up and down a lot for extra stability. Otherwise there is no need for it. The fit should be such that you should be able to slide two fingers between belly and the connecting belt. It should neither be tight nor be too loose. You can see that the Back Cinch is connected to the front cinch to keep them in equilibrium. Otherwise the back cinch could slide backwards. First put the saddle on and then breast collar, front cinch, rear cinch and then breast collar is connected at last. While removing you have to do the reverse way. That's it.
