I have a simplicity pacer that stalls when the PTO is engaged. If I disconnect the belt from the pto to the blades the mower does not stall. As soon as I reconnect the belt to the blades the mower stalls when the PTO is engaged. I checked the mandrels and they are not bound and I have replaced the bearings in one of the mandrels and that did not help. Any suggestions/advice would be greatly appreciated.

I think I may have figured it out. Checked connection on my coil (may have been a bit loose) also re gapped coil to about 0.020". One side was a little tight and the other was a little loose. I'm going to put everything back together and try to mow today or tomorrow if the rain holds off.

I want to rule out other issues before replacing the PTO. I am thinking that it could be in the operator presence switches or circuit as now the mower will run when the parking brake is engaged but stalls shortly after the parking brake is taken off. The engine is also not starting as well as it has in the past.

If when the parking brake is on and the motor starts and you release the brake and it cuts off then you do have a presence switch problem as long as it isnt when the pto is cut on. the internal electrical component of the clutch it going bad only if it does it when you turn on the pto meaning that the cltuch is engaging to hard stopping the motor from free spinning as you have engaged it but if you disconnect it all the way including the belt and it starts and runs fine then it is the pto no questions asked no way around it.

Found a loose connection in the kill wire that runs to the coil. Just mowed for 20 mins w/out issue. Keeping my fingers crossed. Thinking vibration from motion/ blades spinning causing loose connection to fail and kill engine?
