Normally I never really consider it because I never know if it was me or the equipment (like what Mike said). But these marks…are OBVIOUSLY ball return marks. They are exactly the same in depth, length, and appearance and directly acres from each other. Kinda like when you use a wrench and it leaves those jaw marks. And it resulted after the ball return broke down and 3 balls got stuck in there and the mechanic had to manually turn the wheel to get them out.

Oh well. I still had good shots with the ball afterwards so it didn't seem to really hurt it.
