I belive I have a 30sctt, but could be wrong. The numbers where hard to make out. The chain going from the front of the hilo to the rear has come off. The company I am working for does not have info on this unit. I'm not sure if the whole chain needs to be replaced, or if the is someway to put it back together using this one. The rear tire spins fine, and that chain is intack. But the other one is laying on the ground. Any help in the right direction of fixing this will be great. Thank you
