I'll get a video out there but it sure pushes and back drags material. Even tilting and unloading works great. Just don't expect to be loading material, that would be a good bucket swap.
Again another great J bros video, I thought I was tripping when I had to wedge a piece of wood to keep the lock pin up, because the spring is so strong. But I see you had the same issue. I was thinking I am going to have to notch the bottom of the catch because they wouldn't stay in the open position for me, they would keep popping back in the locked position.
