I own a 22 year old 18 hand Clydesdale, we typically only use it for pulling a sleigh in the winter. However last summer I decided I would saddle her up. The person I purchased her from had said that they rode her one time and after they climbed a small hill she decided that was enough and laid down. It took them about half an hour to get her going again. That is the kind of horse she is these days, with her age and being overweight she is an incredibly good natured horse. I will sometimes lead the young kids around the field with them on her bareback. So decided I would give it a try, I put my western saddle on her, put some reins on the halter and off we went. I would agree that it felt like riding a tank. We rode about half way up the trail on our property, I decided that was enough I didn't want to push her too much. She has a nice gait but they are powerful!
