I have a husqvarna riding mower. 23 horse . I stopped tractor and put on brake to remove a ball from yard. Now the tractor won’t move forwards or backwards. And it not the transmission rod on the back, I’m aware of that. The bungee for the battery had fallen off, is there something that was dislodged or what. It runs and starts fine. Pto works, just won’t move. Also I can push it with that rod pushed in, when usually it won’t push unless pulled out:
