Just had the motor replaced on a melroe bobcat 773. Drove it around for maybe 2-3 minutes, pulled in back into shop to clean it all up and replace parts and paint. I replaced the seat andhad a problem with the sensor but got it working. I raised the bucket and noticed a hose with a pin hole leak. I hooked it up and now the bobcat move forward and reverse but only " groans" when I try and turn. It isn't the interlock but acts like it just pushing against a wall or something. It will not turn right or left. Any help would be greatly appreciated Thanks!!
