I've a
bx23 2007, it's probably got at least a dozen safety lock outs. Sounds like you use your tractor "somewhat" infrequently? I will let mine sit for months at a time then when I use it I am using it some every day for maybe a week or two. I have a dickens of a time getting the machine to start when I first get back to using it as described. I've replaced batteries, tried jump starting, everything and can't get it to start. It's a TLB and I've got the 54" mower deck on it as well. I have ( i hope) finally figured out how get it going after it sits. Try wiggling every control there is, PTO height, pto engage, neutral turtle rabbit, treadle pedal, lift seat drop down sit down hard, keep jiggering the control switches, sooner or later you will trigger the sticky culprit. I know sounds crazy especially if anyone is watching you bouncing up and down on the seat, wiggling every lever but seriously, these safety switches are a pain but as mentioned by others there for good reason. Don't try to disable them. If have to troubleshoot and fix, but from my experience with my bx, I have to sometimes jigger things around for a as much as 5 minutes, get off walk away come back in a few minutes to a release frustrations and ease the fears I've got bigger problems. The other day I cranked the tractor to pull it off the trailer, the PTO was engaged, but the engine started anyway, good thing the mower deck was clear of foreign matter, but that is safety switch that is obviously not working, they are a pain I need to replace that one. FWIW Good luck.
