I have a 2009 Bobcat CT122 with 139 hours on it. I'm having an issue where The loader lifts/dumps/etc extremely slow empty and not at all with any load. Also having hesitation with the rear arms lifting and no downward pressure. I've let the tractor and oil warm up, well over an hour and no change, with rpm maxed when in use. All oil levels are full and all connections have been cleaned and checked for leaks. I bought this unit used and being not too familiar with Bobcat I'm looking for any help. Thanks for your time!!
