SOURCE: pto willl not engage

Hi mate, Although my trade is repairing turfcare machinery, I have no experience with this model, so I will try my best. Firstly, the clicking you hear will probably be the electric clutch engaging/dissengaging. Firstly, see if you can get the clicking with engine off, keyswitch in first position/on/lights on dash. You may have to place something heavy on the seat and have traction pedal in neutral. MAKE SURE YOU DO NOT ENGAGE THE STARTER MOTOR/START THE ENGINE THROUGHT THIS!

Now have a look under the footwell on top of the deck and try to determine where the clicking is coming from, there will be a clutch there somewhere joining the engine drive pulley to a deck pulley, Also at this point check that both belts are on and with the ENGINE OFF! spin the blade/blades with your hand and ensure that the deck belts are not slipping on the deck pulleys. If they are you will need to establish where the tensioning system is. (Sorry i know pretty vague)

Back to the Clutch, once you establish where it is, engage the blades ENGINE OFF! and you should feel a greater resistance turning the blades as you are now turning the engine as well, beware though, it is theoretically possible to start the engine by doing this, but you will almost certainly not be able to spin the blades that quickly by hand.

If it is clicking to engage but not turning the engine pulley when spinning the blades by hand, then try tapping the clutch lightly as it may not be fully dissengaging.

I would put money on it being either one of the belts coming off/snapping, the blades jamming or the clutch not engaging fully.

If you find that the clicking is not the clutch engaging and its actually getting no power to the clutch then you need to go back to the pto switch and go through all safety switches! (good luck, it usually ends up with me bypassing them or running a new cable to the switch,then, smoke, shouting, swearing etc etc!) Either not advisable.

In doing all this you should have been able to have determined the problem be it one that I have mentioned or another.

Hope this helps,
Chris.

SOURCE: Husqvarna Mdl YTH2448 Riding Mower - Electric PTO Not Working

It sounds like your charge system is not working. If you jump the battery the engine will run with a weak battery but the pto clutch needs a strong battery to stay engaged.Try this to test it,after you jump it leav the jumper cables hooked up and try to engage the blade clutch,if it runs it is either a battery that wont take a charge or a charge system not working. If you put a volt meter on the battery while the engine is running and the voltage is 13 volts the charge system is working and the battery is bad.

SOURCE: Mower deck PTO switch will engage when pulled but stop when rele

The PTO switch has failed. There is an internal spring and plastic parts in toggle switches that keep them in the actuated position. It's not practical to take the switch apart to fix it, but replacement switches are readily available - probably $12 - $20. It's a good idea to disconnect the negative terminal from the battery before you do any electrical work. Be sure to put the wires on the corresponding terminals of the new switch. Good luck! Please rate if you find this helpful, thanks.

John Deere eztrak mower went over a rock today and now the mower won't engage


hmm strange are the belts driving the blades ok if so then the PTO could be damaged but if there's no sign of damage it maybe a bit frozen up/locked up have the engien off but turn the key on and engage the PTO switch and manually turn the PTO (not by the blades please....dont want to have your hand taken off) turn by the PTO itself and if you hear any clicking sound disengage the PTO and engage a few times to ensure your hearing the clicking sound of the PTO turning on and off and it should be back to normal also check any connections going to the PTO before doing the manual work of repairing the PTO

PTO wont engage


Check your fuses
check the PTO switch
insure all of your safety switches on the mower are working correctly.
You can use a voltmeter to check all of these switches
if all of this checks out you need to replace the PTO clutch.

Engine runs, but when I engage the electric PTO why does it go dead?


Newer mowers have a safety interlock that prevents the mower running when going in reverse. My guess is that the reverse switch is on and when the PTO is activated the engine dies like you shut off the key.
Second idea is that the device the PTO drives is frozen up. Test this by trying to see if it turns with the engine off. When you engage the PTO the engine chokes down because it can't turn the PTO.

most likely the engagment switch, usually yellow knob. the seat safety shuts the mower off so if the mower is still running it is not the safety under the seat.

My electric PTO on my Husqvarna Model YTH180 does not engage


I'm having same problem. I think it's the switch, Running the system reads 14.6 volts. pull the switch No power to the lead that goes to PTO. if I jump 12v to the clutch the PTO engages fine. also changed the relay. Just wondering if there may be some other safety switch I may be missing? Hopefully it's just the switch. I dont know the likelyhood of those going bad the mower has tractor has 500 hours on it and looks damn near new.

When I engage the front PTO the engine dies.


There is somthing in the PTO that is binding up. I am assuming the PTO is for the mower blades. The belt(s) could be binding up, not on the pulleys, etc. The blades should turn by hand easily.
