which come in a limited range of sizes. Custom-made saddles may be able to have further alterations made to a standard tree. Regular - If a manufacturer has a 'regular' barred saddle it usually falls between 5¾" and 6". Often 90 degrees Semi Quarter Horse - This type usually has a gullet width of about 6½ inches and steeper bars than most other trees. It is the narrowest common tree and, despite its name, fits many breeds of horse. Often 90 degrees Quarter Horse /Full Quarter Horse - Terminology varies with manufacturer, but overall design is intended to fit stock horse breeds such as the American Quarter Horse. This type usually has a gullet width of about 6¾ inches, but may be up to 7 inches. It usually has a flatter pitch than the Semi-Quarter horse tree. Different makers tend to give different gullet dimensions in Quarter Horse and Full Quarter Horse trees. Usually between 90 and 94 degrees Arabian - Depending on manufacturer, has a 6½" - 6¾" width gullet but a very flat pitch to the tree. Usually has shorter bars than Full- and Semi- Quarter horse trees. Intended to fit smaller horses with short but wide backs, such as the stock horse-type Arabian and Morgan. Haflinger (7½" gullet) are very wide, designed for semi-draft breeds such as the Haflinger horse, which are short-backed, heavy, low-withered horses. Often have a flat pitch (usually greater than 94 degrees) and very little rock. Draft - (8" gullet), are designed for riding Draft horses. Usually greater than 94 degrees Pony - narrow gullet, flat pitch to the bars, very short tree, designed for children and smaller ponies such as the Shetland and Welsh pony. Rigging Saddle rigging refers to the arrangement of rings and plate hardware that connects the billets and girthing system that holds the saddle on the horse. Western saddle rigging can be either single or double. The front rigging consists of metal "cinch rings" on each side of the saddle to which a long, wide strap called a latigo is attached for holding the front cinch that goes around the heart girth of the horse, just behind the elbows. The back cinch is placed around the widest part of the horse's barrel, and is attached to the saddle either by reinforced slots in the leather skirting of the saddle, or, in particularly heavy-duty models, to a second set
