I have a 2018 B2650 with an intermittent electrical fault. It keeps blowing the OPC (Operator Presence Control) fuse after different amounts of running time. I have been trying to trace down the problem and I am replacing safety switches as I go, because I have not found a definite smoking gun yet. In the course of replacing the neutral position safety switch for the hydro-static drive pedal, I pulled the pin out the peddle damper and replaced it (with some difficulty) and now the peddle seems to be sticking. Any advice on freeing up the pedal?

With the fuse blowing I would suspect a wire shorting to ground, possibly from a safety switch. Seat switch is a good candidate, I think on some tractors they come loose and then short the wire to chassis (ground). Check in the schematics which wires are supplied by this fuse.
I do not know the fuse rating, but what works for me in those cases is replacing the fuse by a 12V and 55W bulb for example for a 5A fuse. When it lights up the short is present.

Which pin are you referring to? There's multiple pivot points in the treadle pedal linkage and multiple places that could restrict pedal movement.
Mine was pretty much seized up when I bought the tractor and I had to disassemble all of it to free it up and lubricate everything.
