hello men of the riding mower...bought a nice looking used simplicity express...it never seemed to run well with the mower engaged....the mower deck made a a rough noise as it operated..sort of wow wow wow wow...but it cut grass well....not when the pto is engaged it kills the motor ...as soon as the pto is engaged it runs so rough the whole mower shakes...the spindles turn freely and there isn't any serous slop in the bearings as I can tell....wonder if I don't have a motor problem when operating under load?....thanks for any info you can advise.....it isn't running so well now either but I was able to get it running at what seemed to be full throttle for a couple of minutes...then as soon as pto is engaged..shake, rattle, and roll again
simplicity engine stalls when pto engaged

Welcome to the forum. Check the easy things first. Make sure you can get 3/16 to 1/4 inch spark out of the plug wire. Is your charging system working. If I'm thinking right, it would be a battery/coil ignition. The PTO draws a lot from the battery and if its too low it won't run right either. Maybe a little fuel system cleaner through the carb. A lot of the guys like seafoam. Post the model numbers of the tractor and engine. It will help us help you better.

But, maybe your motor mounts are bad?
Put a pry bar under there and see if there isn't a lot of movement.
Otherwise maybe you have an engine tune up problem.
