Flail Mower Oversized flail for undersized tractor ok?

[TractorTYMe]

Congrats on a nice flail mower. I have a chinese one made from pallettforks.com. So far so good, but they are not good about spare parts outside certain parameteres. Like the bracket holding the rear roller and bearings are wearing on the face down side, eventually I'll need a new one. You see it on picture holding the rear roller.
