I have a Husqvarna YTH21K46. What would cut the fire to my anti after fire solenoid ?

Any one of the safety switches that shut off the tractor will also shut off the voltage to the fuel solenoid. On my mower it is getting out of the seat without turning on the parking brake and of course turning the key off. If the solenoid did not shut off when the engine was shut down it could backfire from the red hot carbon on the head and piston and possibly break a connecting rod . I wish the manufacturers could have put a L E D light panel on the dash to tell us witch safety switch was not happy.

I have an 2004 husqvarna yth2148 that starts fine. when i take my foot off the break/clutch it shuts off. i checked the sensor under th eseat and its fine. what could be the problem

all the safety switches tie into a central relay which keeps you from spinning the deck and/or starting the engine unless everything is copacetic. start by replacing that relay as it sounds like you have a problem at that point.

Husqvarna Riding Lawn Mower 46 Cut model #454140010G MOWER will not ingadge

I can not say this enough, check the safety switches. There should be one on the seat, the clutch /brake pedal and /or the equipment pto switch. Also, check the wires running to these switches. They tend to move and vibrate as you mow and a worn spot in the wires can cause a short, resulting in the mower not starting.

Good Luck!!!

Want to disconnect the auto shut off when you get out of the seat

Warning: Not a safe idea to disable a safety switch.

If you really want to do it under the seat is a little round switch with two wires under it. If this switch is normally open then cut the wires and cap or use electrical tape to seal the ends. Then test to see if works. If not working then the switch is a normally shut and wires have to be stripped of the last inch of insulation and twisted together, capped and taped. Test to verify.

If really helpful, please rate.

Seems there is no power past the safety seat switch. Can I bypass the switch? Key will not click when turned. Thought it was the selenoid, but have tried screwdriver across selenoid, and the mower will...

You can put a fuse or a wire jumping across the safety switch under the seat. This is the most common fix you will find for a faulty safety switch. Do NOT do this if children will be around you while you mow or if you let a younger person drive the tractor! That could result in death or serious injury if they got off of the mower while the unit was still in motion.
