4600 gear ratios

[turboseamus]

My 4600 is a power reverser 12x12 transmission. Looking at the little sticker on the fender, I notice that A4 is the same speed as B1. So far, almost all of my work has been moving snow, and I知 using B1 and B2, not really stressing anything. I was wondering if anyone knows which gear is stronger A4 or B1? And by stronger, I mean, less likely to break if I知 working it hard. I tend to drag as much as the tractor will when I知 logging.

I suspect you have no need to worry.. same speed likely means they are the same gears or at least the same gear ratios.
