You need adjust your shift linkage. Your manual should tell you how.

SOURCE: Bolens riding lawnmower st100 pto won't engage?

I think Mickey813's answer is correct. On the ST series mowers, there are 2 safety interlock switches that will either prevent the PTO from engaging or kill the engine once the PTO switch (or clutch) is engaged. One of these switches has likely gone bad or the wiring came loose. Oddly, on my ST120, I completely removed the seat safety switch and the 2 wires are disconnected and everything runs fine. If I directly connect them, the clutch or PTO kills the engine when they are engaged. Once when my PTO wasn't engaging, I temporarily bridged the 2 wires with a jumper, started the engine, then engaged the PTO (which killed the engine). After that, once I removed the jumper, the PTO would work like normal again each time I engaged the switch. It's like I reset it somehow by jumping these 2 wires temporarily. Hope that helps...
