3616 hydrostat rear lift arms stuck in raised position

[JimnAZ]

Hello,

Just got done using my backhoe and wanted to switch to my box blade. When I go to hook it up I cannot lower the lift arms. The speed control is not in locked position, fluid level fine and hose connected correctly.

Anything I can trouble shoot?

Thanks
Jim

turn the black knob under the seat to open the valve. It controls the down portion of the 3pt. You may have to turn it 4-5 turns out, but the arms will drop.

Yes that's the speed control and it was already open. I ended up getting them to work. Just kept playing with it. Thx
