Try unplugging the pto, start the mower, then engage the pto switch. If the fuse still blows trouble is somewhere in the mowers wiring if not the ploblem lies in the pto. hope this helps

How do you disengage the clutch after being left on when turning the engine off?


You can kill the engine with the PTO clutch on and then turn the PTO off before trying to restart because the PTO will auto disengage when the engine switch is turned off. The engine should not start if the PTO switch is on.

On a Husqvarna 2005 ELS 2448 riding mower, PTO switch burns up, and wont blow the fuse first? Why?


I used to see this on the Kawaski engine machines with an electric clutch, they put a diode between the two clutch wires so as so as to stop any electrical feed back throught the clutch, when the machine is running without the clutch engaged it can turn into a generator.

Husqvarna 17530 stalls when engaging the blade. Seems to run fine else wise/


Does engaging the pedal for the PTO lug the engine down, or does it just die like turning off the key?
If it lugs the engine down, then you need to make sure you can spin the spindle and idler pulleys by pulling the belt by hand. You should be able to slip it around the engine pulley enough with the blade pedal disengaged. Pull the belt up tight so the slack is around the engine pulley and try to spin the blade spindle and idler pulleys.
If it dies like turning off the key, then its likely a safety switch and may require a meter to test which.

The seat switch is has a shunt in the circuit that must be satisfied in order for the rest of the circuit to be happy. Make sure the connections are good, the pins inside the amp connectors will sometimes spread, push out of the lock etc. and if connection is lost will not work. Otherwise a new seat switch will be needed. You might check the PTO switch for continuity, without a diagram or schematic I am not sure how your circuit is wired. you have to have the parking brake engaged to get off the mower while the engine is running and the PTO is Dis-engaged?
I don't know if your "go" pedal eliminated this switch or not. But if with the parking brake engaged and the PTO disengaged, you lift off the seat and it dies, then its the seat switch.

Hope this helped Tim

I have a 26 horsepower husqvarna tractor and when I pull the switch to engage the clutch to motor dies as through the system is shorted. I have disengaged the pully system and the clutch is spinning...


I will offer a common solution although it may not be yours. If you think the engine is dying because of an "electrical" problem and not "bogging down" I would check the connection at the seat safety switch. This is an "operator presence" switch and if the mower "thinks" that no one is sitting on the seat, anytime the PTO or clutch is activated, the engine will cut off because it kills the ignition to the spark plug. It gets a little tricky because not only may the switch be malfunctioning but the connector that plugs into the button switch has it's own internal switch. So what this means is that if the connector has slipped and is not engaged all the way, the internal switch is not made or if the the internal switch is not working, is will kill the ignition to the spark plug as mentioned above. Hope this helps to some degree.

Whenever I engage my PTO may engine bogs down, what may be causing the problem?


do you mean when you engage the cutters? if so then chances are on of the blade spindles may be seized or stuck, disconnect the belt from engine pulley and try turn the blade spindle pulleys by hand one at a time to see if they are spinning freely

Husqvarna yth2448 pto switch kills motor/battery will not charge


you may hav a bad alt. problem with the mower dying when you engage the pto is most likley a bad sensor or wire unplugged on the seat sensor.the way it works is if the blades are turning and it dosent sense you being on the seat the mower shuts down.this has been standard on mowers for quite a few years now. it keeps the blades from cutting you up if you fall off the seat while mowing. as for charging i would try cleaning the battery connections and get the battery checked first.

Engine chokes & dies when deck PTO engaged...


you need to start with your electric clutch and then backwards to your idler pulleys and deck spindles and bearings.
your electric clutch should almost stop the blades instantly when disengaged ,check the center bolt in the clutch to be sure it is tight also
remove the belt from the electric clutch and energize clutch any noise? sometimes the bearing goes bad in the clutch itself.
check all of your 3 spindles for noise and loose. remove belt and spin by hand and listen for quiet and they should turn free with no binding
check blade tightness
any item the belt goes around needs to be looked at for secure and operable.

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.
