Today I bought a used 23HP gator tail. I have never owned anything but a long tail so this is all new to me. I got the motor for $300 because the owner and I thought the motor was froze up. Once I got it home and started looking it over I noticed the reverse caliper was froze. I unbolted the caliper from the frame and the motor is free and turns over. Can you rebuild the caliper or buy a new one? I don't see it as an option on the parts web site.
