1720 transmission went out

Shop says the bevel gears are gone and they'd need a new tranny to fix. can't find any used. Guess I have to scrap it? Thing is in great shape and had since new.

part # is 717-3048

Not sure what other tractorts use this exact setup?

Just a quick question, without taking the transaxle apart, how could the shop serviceman determine that the problem was with the bevel gears? Is there a test that can be done to determine that?

@ironman THANKS!!! Those all have the tranny part # 717-3048 ?
This may help me find one that's closer to me in Hershey, PA since I can see other models the tranny will fit.

They did take it apart. I guess he saw that the bevel gears were gone.

Ok. I found a guy in Denver PA, and he had a used Tranny. He specializes in all older cub models, 1 hour away from me! Super nice guy and he let me pick it up today. Also. The following models use the 717-3048 Transmission:
1020, 1320, 1420, 1720
1330, 1430, 1730.

I’m attaching some pics of the tranny.
