Hi all. I've had my Snapper NXT 2346 for a couple of months. All has been fine until yesterday when the PTO switch stopped engaging the blades. I was suspect of the switch itself, and then I noticed that the headlights don't work either. Battery has good charge. Push-button start/stop seems to work normally. Electric mower deck height works. The mower has been used in quite a dusty environment lately. Are there any fuses between the PTO switch and the PTO clutch? If anyone has a link to a schematic for this model it would be greatly appreciated! Thanks.
