Answer to "mower deck will not engage when the PTO switch is turned on?"Husqvarna RX5424 Last year we had some issues with it not wanting to start, but it was the seat switch out of place, and Kept blowing the fuse under the seat. Its fine now and starts and runs fine. However, the PTO will not engage. I’ve traced the wires to the pto clutch and switch, and everything looks fine. Can you give me some ideas of things to look at? Is there a fuse or circuit breaker? It will not start with the PTO engaged (good), but that tells me that there is a good connection somewhere. I unplugged the switch and plugged it back in. I unplugged the harness by the engine and cleaned it, it looks good. Doesn’t look like any other broken wires. Could it be that seat switch acting up again only not letting PTO start? I think I will try to hard wire the PTO clutch harness and see if it engages then? Then it has to be a safety switch or PTO switch?
