Make sure you get the saddle that fits your horse! Try the saddle tree on your horse and we'll evaluate the fit for you. Shipping a saddletree requires a $125.00 deposit plus shipping. The $125.00 deposit is applied to the purchase price of your Mountain Horse saddle. Mountain Horse has a goal to not only sell you a saddle, but to make sure you are satisfied with your purchase. To achieve that goal, Mountain Horse offers you help with saddle fitting. For Mountain Horse brand saddles, you can choose to have the actual saddletree sent to you! You then put the saddletree on your horse, take pictures (instructions will be sent to you), e'mail the pictures to mtmountainhorse@yahoo.com and expert saddle makers will evaluate the fit for you. From the pictures, the saddle maker can tell what adjustments need to be made to ensure that your horse has the most comfortable fit. Saddletrees available for fitting purposes: 6 ½" flex tree (semi QH). This saddletree flexes to about 6 ¾" when pressure is applied (rider in saddle). 7" flex tree (full QH). This saddletree flexes to about 7 ¼" when pressure is applied (rider in saddle). 6 ½" gaited wood tree* Good fit for not only gaited horses, but for horses with a narrow high wither, sway back or big dip behind the wither that aren't exceptionally broad otherwise. Usually a good fit for most Thoroughbreds 7" gaited wood tree* Good fit for MOST gaited horses and other breeds that have big shoulders or lots of shoulder action. *Gaited trees were specifically designed for the gaited horse breeds. Bars on these trees are flared outward at the shoulder and the gullet is taller so they do not pinch the shoulder and they aid the gaited horse in comfortably moving into their natural gaits. Work for other breeds too. Draft wood tree** **Draft horse trees are specifically built for your draft or larger horse. The bars are flatter to fit a broader back. Usually send 7" or 7.5" for fitting...can build in 8" gullet as well Friesian wood tree--great design for a Friesian horse. Fit other draft and large horses as well that have a tall wither, but are still broad. Gaited type front, draft width bars. 6.5" or 7" Mule flex tree 6.5" or 7" Mule polymer tree We recommend the mule polymer trees over the flex for most mules. The polymer bars are straighter and fit most very straight backed mules better than the flex. We can build these mule trees in wood if you prefer for $85.00. A-Fork or Wade trees --if you order an A-Fork or Wade tree please specify if you animal is mule or horse and if narrow or wide build. NEW--now have a flex gaited tree in a 7" gullet size (seat size 16 and 17 only) Please do not order this tree for fitting if you need a different seat size. It does not fit exactly the same as a 7" gaited wood tree, it is a little wider. Saddle trees ship UPS Ground. (Because of the box size required, USPS does not calculate shipping correctly through the webstore)
