If the switch is wired on normally closed side, it may just have come loose from where it is mounted. Looking at picture, it would seem to make sense for the switch to be actuated at the "off" position of the lever.Its john deere 5075e model and yea its a lever that turns off and on the PTO no button. So everything works but the PTO engaged light stays on even when the lever is off position maybe theres a switch in the lever i’ll take a look and get back
