So, I bought a LT1042, 2007. The guy said the pto switch was out. I replaced it and it was not the issue. After doing some research, I found out that the mower should have a Kohler engine. Well there's a Briggs 21hp instead. So the engine was replaced at some point. So I went to pull the actual PTO clutch off of it and it was rigged. Someone had welded a small extra piece of metal to it in order to brace the clutch when engaged. It actually looks pretty solid. My problem is I don't know if the PTO clutch that I took off is the PTO clutch from the Kohler motor or if it's a different one that fits a briggs motor. There is no part number on the PTO clutch itself. I'm assuming that it is one specifically for a Briggs motor since I'm pretty sure they're not interchangeable?
