Safety Switch issue

[Peter K]

I have a 2019 B2650 and have had an electrical issue that has just started to occur and could use some input. Recently when I am using my finish mower with the rear pto engaged and as I back up, I blow a 5amp fuse that control the dash board. It has happened at least 3 times. I replace the fuses and continue moving forward with no issue, as soon as I back up with mower engaged the fuses blow. I tried backing up without the pto engaged and it seemed to be ok. However I was gingerly doing it as I have to get more fuses. I see from many treads with similar issues, but mine only happens when backing up with the pto engaged. I suspect it has to do with the safety switch in the pto level, but where is it located and how do I get to it. Thanks for any help

Interesting. Is it possible that the treadle linkage has rubbed a wire bare causing a short and blowing the fuse? That wouldn't address why it only (?) happens with the pto operating though.

As RjCorazza wrote,also check for unnormal drag on pto shaft.
