This sled is the best one we have ever used. We added the belting a year ago as the bottom was wearing out. It is about 8 years old hand has had countless calves in it. Some do escape but not many, usually the ones that were old enough to already be on their feet. We added about 20 feet of tow rope as quite a few of our cows would prefer not mixing with humans. Tow with a quad, horse or on foot. Pulls heavier with the belting than it did when it was new and plastic.@gcreekrch Question: I have seen these sleds with the "foot hold"…does it actually work? Meaning does the foot stay put, keep calf down and in place? I like your baler belt…at least it looks like baler belt. We have developed many baler belt recycles here too.
