Why doesn't my Toro z master PTO not engage

if this is got the 27 hp kohler engine, I know exactly whats wrong with it , due to grass and engine oil building up in a short time under cylinder heads , it actually makes a tight ball of grass and stuff there !! this holds the engine heat and ruins the ign module that's just above it there , I put two on in one season ( tractor runs 6-10 hrs day 6 days a week ) I finally gave up I bought a Kawasaki 27 hp twin and installed it , now its run for two seasons and no problems
engaging the pto has nothing to do with it , it would cut off if you just drove it around for 15 minutes

Could be a bad bearing or could be something rubbing against something. Are the blades sprung so they are touching part of the body or something they shouldn't Just ideas to check out.

can you hear it activate the pto or does it turn if not check fuse if not blown check voltage to pto if good you have a bad pto replace it

Check under the deck and make sure the blades can spin freely, there will be resistance but mostly check to see if they are stuck. If they are not and can move, you can try to remove the belt from the pto, engage and see if it spins then. If it does not than there is probably an issue with pto clutch

Check for frayed wires on the safety switch for the blade engagement

Hi
one thing to try sstart up ngine le it warm up and get a screw diver and turn the mix screw on the carb 1/4 turn out and try that engage PTO if nothing turn another 1/4 if nothing turn engine of and turn mixure sew all the way in very easy dont force it just when it stops turn 1 and 1/4 turn to 1and 1/2 out now start it and try pto if its still slowing down turn another 1/4 turn out now if that didnt work just make sure you have a clean air filter and fuel filter and spark plug before you do any of the above then u will need carb rebuilt please use fresh gas otherwise you will very low power

check the throttle spring in the front of the engine.It is hooked to a loop and when going near a bush it will push in and slow the rpms down.If you locate it pull it out and the RPM"s should increase.

not with toro. this usually happens if cutting high grass. try taking it apart, clean it. make sure belt is not stretched out and jammed.

I hope this will help you...under the side panels on each side of the mower, there are "reverse lockout safety switches", they are supposed to stop the blades when both handles are pulled back. If one or both of the switches are out, the deck will not engage. Also, under the right side panel (when sitting on seat) there should be 3 relay switches, the one closest to the motor controls the PTO., if this is out, the PTO will not engage.

the electric clutch that operates the blades needs replaced
