I have a TYM 2515H with a BL 150 loader, tractor has 21 hours. Scooped some dirt, dumped it went for the next scoop and now the control lever is frozen. Bucket will curl and dump but the loader will not raise or lower.
Do you mean the joystick won’t move or the joystick moves but loader does not?
If joystick moves I would suspect one of the quick disconnects for raise lower is partially connected. You will most likely have to support the weight of the loader to reconnect those but you could first try putting loader in float to see if it might slowly drift down. Doubtful but possible.
