I have a 1988 575 skid steer. I sent it to a garage for maintenanceI inherited it with my new house -maintenance was not really done. The steering linkage was always a little loose and whiny. It came back from the mechanic now it always wants to turn to the right. It is tough to start and turn off For new pumps it’s $20,000. I can’t put that money into it. But it is worse than when I sent it. Is there any information on how to correct this. I am in PA.
