Why does my Simplicity Citation keep blowing the PTO Clutch 20A Fuse?

20A ATC fuse behind dash. Likely it will blow again unless you find the problem. Follow cable from PTO switch towards clutch below engine. Look for cuts, scrape, mice damage.

it is not supposed to start unless some one is in the seat
now for your problem, if engaging the cutter deck blows a fuse then check the wiring for a wire that is cut or shorting out on a lever that moves when the cutter is engaged

There are several things that can cause the fuse to blow. PTO stands for Power Take Off and most likely this will not be the problem unless it blows the fuse when it is turned on. What you are saying is the fuse is blowing by just turning on the switch will be a short which can be anything from a pinched wire, shorted diode, short in the stator. bad voltage regulator.etc

IF i'm not mistaken, this model has a safety on it, when your mowing and back up, the blades temporarily disengage until no longer going in revesre and then start back up. These are famous for getting out of adjustment, if it is out of adjustment the sensor is registering as if you are backing up. I hope this helps you

Clutch is likely bad.....might check for bad wiring of perhaps even a relay...but most likely the clutch itself is shot. PS....they are not cheap.

could be the safety switch for the pedal

Most likely there is an internal short in the PTO clutch, but it could also be in the wiring, which is way cheaper to fix! So, with the engine off, get down on the ground, find the PTO clutch (it's between the two pulleys under the motor) and trace the wires that go to it. Look for a worn spot in the insulation anywhere, especially likely where the wires pass through the chassis or if they've touched a belt or other moving part. If you find a wiring problem, just splice in a new wire.
Ok, if you found nothing, then unplug the connector that connects the wires from the PTO. Start the engine, drive around, engage the PTO switch (of course, the blades won't spin). If the PTO fuse does not blow, you've proven the problem is in the PTO clutch and you must replace it ($150 or so, sorry!). If the fuse does blow, that's good news, you just have a short in the wiring or in the PTO switch itself. Disconnect the wires from the switch to differentiate those two possibilities. The PTO switch isn't too expensive either. Good luck! Please rate my solution if helpful.

Sounds like you have a short circuit, either in the PTO clutch, or in the wiring that goes to it. Inspect the wiring for any obvious spots where insulation has rubbed off or burned. Also look at the wiring at the back of the PTO engagement switch for these signs. Before buying an expensive PTO clutch, unplug its connector. Drive around with the PTO switch on (even though the PTO won't activate and the blades won't be engaged). If the fuse doesn't blow, the problem must be within the PTO clutch. If the fuse still blows, it must be in the PTO switch or the wiring from there to the clutch. Use an ohmmeter to trace and find the short. Good luck!

If you changed the belt make sure it did not interfere with the wire that runs from the pto clutch, sometimes that belt can rub on the wire and wear through it,also if you had the clutch off make sure you aligned the steel retainer bolt that sets in the alignment hole on the pto clutch,this keeps the clutch from spring when disengaged if you don't get that pin through the hole in clutch it can push on the clutch and bind it.Also it may be possible to plug that pto switch in backwards.Also if you jumped the fuse out it may now have burnt the switch or wiring somewhere.

Form what you are desribing you have a direct short, probaly in the wiring going to pto. I t has rubbed somewhere and is causing your short. Unplug the wires at connector close to your pto clutch and try it again and see if fuse stuill blows after you unhook it.

If the fuse still blows it is in the wiring going back up to thje switch. If the fuse does not blow after unhooking wiring connector the problem is in the clutch.
