John Deere Fuse Blowing when Starting

[Hickmancw]

I have a John Deere Z345r zero turn mower that blows the PTO fuse every time I start the mower, without actually engaging the PTO. I have taken a look at the wiring haven't found anything damaged, I unplugged the clutch, and it still blows a fuse. I have not been able to find a wiring diagram online for this mower. Does anyone else have any suggestions? My next step is to replace the starter solenoid

You have a short on this circuit. Find out why and where on said circuit. Wires rubbing, mice chewing.......

Call JD and ask for a diagram. I bet they have a toll free number.

Keep your original starter solenoid. Has zero to do with the PTO.

We can guess all day and be wrong.

Please provide the product label (PIN) information off of the white tag above the rear wheel.

Next, check the engine for a product label or a series of numbers stamped into the top of a valve cover.

Let us know what you find so we can actually help you with information to go by.

Thank you for the info I visually inspected the wiring and cannot find any damage. I am thinking this short could be in the actual key switch. Its odd the PTO fuse is the one that is blowing each time you turn the engine over. I will give JD a call, I spoke with a dealer but haven't gotten anything from them as far as a wiring diagram. The engine itself is clean free of dirt and getting full air flow

Need to put a multi-meter on the PTO circuit. Visual doesn't do much for wires carrying current.

Check the seat safety switch wiring carefully, I have seen several that rubbed through.
