I think a lot of people that have huge 2000 lb. plus horses would be happier with 900- 1300 lb. ponies. Some use half draft and half light horse, but a pony of draft type would weigh about the same as some of these crosses and be thicker built and more compact, thus easier keepers. That means a lot if you make a living with them as I do. I log with them and keep the better logs for lumber and sell the rest as firewood. I sell abut 150-200 cord a year and cut and sell year round.
To dig with a slip scoop the dirt must be fairly loose. If it isn’t they used a hook shaped ripper to loosen it first. Your lines must be around your back under one arm only, not around your waist, because if that scoop trips unexpectedly (and it will) you want to be able to get out of its way. Ideally your lines should be just long enough that when starting out between handles you can stop horses by leaning back and to control speed. You don’t want to be leaning too far forward, it’s like a walking plow, you must be comfortable, it’s hard enough work without making it harder.
