I was going to do what you just did with sidexside pics. If you look there is a a taller boom mast that is attached to the tractor. The loader now has a new boom arm attached to a new bracket that raised the cylinder up. Also you will see there is a new top bucket bracket that rotates too. It is attached higher on the boom itself in the smaller hole just below the big tube brace hole that guys like to stick chains or shovels in.
What I can't see is what the the top pin on the loader arm that the bucket sits on looks like now or the bottom pin?
By raising the cylinder and adding the extra boom arm is probably what gives you the extra lift capacity, plus the cylinder is shorter now and is attached to the new bracket that helps keep the bucket level. The bracket looks beefy and is definitely stronger than the end of a cylinder rod. That also is helping in the lifting more weight. They changed the dynamics for the better I suppose?
Just what I can see in the video pic and the other pic.
Hopefully it will be available soon and TTWT will get his hands on one! Lol
