Needed : Two transmission gears for 8 horse 28" cut

[shopteacher]

I have 2 28 " blowers 1 with wheels and 1 with track system.  The track machine is for parts I am willing to trade parts, or sell parts. I need the transmission gears to salvage the wheeled machine.  The design of this reduction gear is poor, has anybody seen this kind of wear, I find it hard to believe that I have two machines with Identical problems.
