If you think your riding lawn mower has blown a fuse, trying to locate that fuse may be the most challenging step in replacing it. While different lawn mower manufacturers have located the fuse holder in different areas of the lawn mower, the best place to start looking is near the mower's battery, according to Sears.
Some manufacturers have made it easy to find the fuse holder. Simply lift the hood. The fuse holder is molded into the metal right inside the hood, near the battery. (See photo at Ref. 3, p. 53) If the battery is located beneath the seat, you may find the fuse holder located beneath the rear fender. Other manufacturers make it more challenging, placing the fuse inside an electrical box, located behind the mower's upper air baffle. (Ref. 4, p. 28) Fuses can also be located on or close to the edge of the mower's electrical panel, above the solenoid.
If you check these locations and still cannot find the fuse holder, check your operator's manual for a diagram of the electrical system, which should display the fuse's location. If you no longer have your manual, it may be available online through the manufacturer's website. Should you be unable to find a manual, call a local lawn mower dealership or lawn mower repair shop and ask for assistance in locating the fuse in your exact model.

Depending on your engine.. Briggs and Stratton or Kohler there are 2 different seat switches that are used to power the PTO clutch. The seat switch can cause the PTO clutch to disengage anytime there is not at least 70 lbs in the seat.
The PTO drive wiring has a 30 amp fuse in it. If by chance a stick went through the belt and tore off the wires at the PTO clutch (Common failure) even after you repair the broken wire you still need to replace the fuse.
Check the PTO clearance gap. It should be 0.012 dis-engaged. Any other value and the clutch will not work correctly. Adjust the clutch if necessary.
There is a 2 pin Pigtail just off of the PTO Clutch that you need to check for voltage at the connector. Probe the back of the wires if you can and your looking for 12V DC under the following conditions.
BRAKE ON or tied down
KEY ON
SEAT (Briggs and Stratton engine only) Someone needs to be sitting on the seat.
Then Pull the PTO Switch out. You should hear the PTO Clutch CLICK. If you hear the click there is no need to check voltage. The PTO switch is a multi function switch and it is quite possible the PTO switch failed. I doubt that the PTO Clutch has failed as they normally give you some kind of noisy indication that they are failing and don't fail straight away.
So.. In short
Check PTO Switch (Red wires) to usually red or brown thru the switch
Check 30 amp fuse
Check PTO clutch wires near PTO clutch (They get torn from something traveling through the pulley)
Check PTO clutch clearance at 0.012
Check Brake switch for an audible click as you depress it some distance No click.. possible bad switch
Listen for Seat switch Click as you slowly add weight to the seat. No Click or any click and it can still be suspect due to the Briggs and Stratton installed engine ones have more than one function.. Ignition and PTO clutch power.
The actual wiring diagram is on page 35 of the owners manal that can be found here:

Lastly... check each of the mower deck blade bearings. A seized bearing can cause PTO problems.
Hopefully you have enough information to solve the mystery. If not just respond here and I will help you.
Thanks for choosing FixYa.
