Engine dies when brake released on huskvarna model gth2548

ck your occupant (seat) switch it might have gotten dislodged or unhooked when fueling it

The first thing I would check is to make sure the drive belt is not binding somewhere.

Hi and welcome to FixYa, I am Kelly.

The power sequence for engaging the blade deck is. Clutch brake pedal depressed, operator in seat, Enage selected and brake pedal released. When the blade enages the engine igniton kill wire is routed through the seat switch AND the PTO clutch. If either the PTO Clutch or the seat switch has a problem the engine dies. Same goes for the clutch brake pedal switch... if the clutch brake is not coming all the way up the engine will die.

If you respond with a model number (example LX2000) I can show via a manual where you need to troubleshoot using a meter.

Do a couple of good bounces on the seat, check the clutch brake pedal switch for clicks and then attempt to an engagement.

Also inspect the PTO clutch wires and connectors for corrosion.

Thanks for choosing FixYa,
Kelly

sounds like you may have a problem with the safety switch under the seat. unplug the switch and try it if it works then replace the switch.

Hi..my name is Keith...and i havent worked on that lawn mower model..so i cant tell you exactly where the safety switch is..but it sounds like the reverse safety switch has failed and the lawn mower thinks you are in reverse..so i would look around your foward-neutral-reverse shifter for it...i hope this has helped..if not write me back

there is a saftey switch on the deck that has shorted out need to replace

First check the seat switch,make sure it is plugged in tightly, these plugs have a safety tab built into them that will cut the engine off if you unhook it,sometimes the plug latch pulls out slightly and this will cut the engine, There are two other switches in the system one on the foot clutch and on on the mower clutch, if you follow the white wire from you ignition switch it will lead you to both of them,check those connections also.

I would check the wires and clean the connectors and make sure seat switch is working. If that is not working, it's like getting off the seat without holding the brake/clutch pedal down or getting off seat with blades engaged. Both will cause engine to die.

Go to searsparts.com type in your model number it should show your diagrams and parts for your mower

Your answer was perfect, when I located the saftey switch it was not working properly.

Thanks a million, Ron
