Key stop fuse

[Cummins67]

I have 96 B1700 and i recently purchased a rear mount finish mower for it. I've blown this fuse twice in 2-3 weeks.. could it be related or coincidence? Any ideas are greatly appreciated. Thank you

Check the wiring from the fuse to the stop solenoid, there May be a frayed spot that is occasionally finding a short to ground.
You might also check the time the solenoid stays in the Pull mode, after the key is turned off. If it pulls and doesn't release after 5 seconds or so... your timer is failing... KennyV
