1640 HST Open Station. KMW-1640L Loader About 30hrs on it. The bucket curl seemed slow when it was purchased in the fall. When Michigan winter hit it turned into extremly slow. Also once the cold hit the Joystick initially felt like the lock was on and it didn't want to move. Tried swaping aroung hoses on the quick connect couplers to rule out a connection issue, and to see if the slow operation moved with it. The slow curl did move to the lift operation once the hoses were moved. As the hydraulic fluid warmed up it would get a little better but was still slow. Took it in and dealer ended up replacing the loader controll valve assembly. That took care of the issue.
