If your arms are already up they can’t go any further. I had a problem on my 2425 where the arms wouldn’t go back down. Under the front of the seat there is a funny looking half moon knob… turn that counter clockwise till the arms drop. It determines how fast the lift arms drop. If that is turned too far down they won’t drop.
My friend and I both have farmpro 2425…. he just had the same problem and it was a melted wire in a 12 wire block connecter . 12 wires in, 12 wires out. Find that wiring block near the firewall and check it out.
