Question about Husqvarna 25HP Hydrostatic 54"Cut Garden Tractor

1 Answer

GTH2548 drive spring broke and I replaced it. Tractor would not start. Replaced battery, start switch, seat switch and PTO switch. Tractor will now start and runs well. However, when PTO switch is engaged tractor stops and 30amp fuse in line breaks. All is good until PTO is engaged. Stumped here?? Could belt have hit something when spring failed?

Tractor will not start and only gives an initial click when key is turned

Check to see if juice is reaching the starter motor terminals and that it is grounded. If ground is ok and no juice then you will have to back trace all of the components in that circuit . Also check to make sure that all of the safety switches are in closed position when you go to start and run tractor.

Tractor will not start sometimes, shuts off when going in reverse with reverse pto switch turned on. Replaced reverse safety pto switch,

The safety switch for the reverse is turning the engine off. A tractor is not in use daily, make sure you fill it with premium gasoline NO ETHANOL because it attrcts humidity and turns it into water after a while.

Blades will not stop after disengaging blades drive belts.. I just put new blades on it and have an extra spring. Not sure where it goes cause manual is not very clear?

i hate to assume, but if the tractor is newer it has a electric PTO and a switch on the dash, most are a push/pull type knob, with the mower off pull know in and out and see if you can feel a click or step in the switch if not the switch may be bad also with mower off turn the key on and listen for a click from the PTO if you do and the switch is off it is broke and stuck in the on position, if your switch is a toogle switch up/down (flip switch) same theory just an other type, but either way unplus the wire plug from the switch and start up tractor and if blades are off you know you have a bad switch just replace with a new one..

With many of these Tractors, as part of the safety B.S., much of the electronics run through the PTO switch. Power to the ignition runs through the PTO.

Hi and welcome to FixYa. I am Kelly.

Here are the 3 safety switches.
Clutch Brake
and PTO Clutch

More ofthen than not the PTO Clutch gets a gap greater than 0.020 between the clutch and the clutch plate and the safety switch is not made. There are 3 bolts with springs and 3 slots in the PTO clutch. Adjust the tension on the springs until the gap is 0.020. Then try a start.

If it does not work:
Check out this diagram.. it is for your mower:

I found your particular model here:

Parts can be located by choosing the diagrams under the small schematic. I think if you adjust the clutch you will be fine. The seat has to be occupied / switch shorted and the clutch brake pedal made to get power to the solenoid.

Respond ehre is you need more help.... Better yet let me know if the PTO clutch adjustment corrected the problem.

Thanks for choosing FixYa,

You may either need a seat switch,pto switch or a park break switch.If the tracter is in nuetral with the park break set,it should start with out anyone on the seat,eliminating the seat switch.If you on the seat and the park brake is pushed and it wont start make sure the pto is off,if it is and nothing happens,then it's likely the parkbrake switch.Also check the connections on the battery,starter and engine block[ground].Let me know how you make out.
