SOURCE: PTO won't engage

If you look where your belt goes around the pulley on your pto, you will see your pto clutch. There are bolts with springs that hold everything together. Try tightening them 1/4 turn and then try it. If it still doesn't work, tighten it another quarter turn. There is a magnet there that might not be contacting properly. I have a 1605 and just had the same problem. You don't want to have to replace it , mine is like $400

SOURCE: engine stalls when electric PTO clutch is engaged

check your spacers to be sure you havent locked the clutch assembly directly to the motor shaft
you should be able to turn it fairly free less some clutch drag

Belt may have come off. Check the wire from the clutch and from the switch, you may have had hungry rodents during off season storage.

SOURCE: Hi,

The circuit through the seat switch may be faulty, get some electrical contact cleaning spray (any auto parts place has it) then disconnect the battery, you must ferret out all connectors and connections. Clean each one and use a silicone type lub when reconnecting. Keep in mind there are likely switches under the mower pan mounted to the transaxle and/or frame.

SOURCE: Mows just fine and then all of a sudden the mower

I had a john dear that did this. I had 2 loose wires that ran into my clutch and I eventually had to replace the clutch. You should check the wire to make sure they're connected tightly and If they are then you might want to be looking for a new clutch.

Exmark lazer HP 19 Kawasaki 50" deck new PTO and new relays blades engage for 30 minutes then shut off engine on. After cooling will engage for 10 minutes then shut off

Engine valves need adjusting.
symptoms: starts ok, runs until engine reaches max temp loses power then stops. can't restart when hot. once restarted runs for a while stops again.

There is very little clerance in these valves and temperature alters the lenth by a few thou and the valve don't close fully losing compression, once cold the valves shrink back enough to create enough compression to start again.

Why would blades just stop when mowing with ex mark lazer Z (model lz25kc604) I had beeing mowing for about 6 hours. Then it just stopped

It sound like the PTO clutch has died.
Test your PTO clutch. It should have a resistance of 1.7 to 2.5 ohms.

Why does my engine shut off after running for awhile with PTO engaged; will restart with PTO disengaged, but shuts off when i attempt to engage PTO?

Does this only happen when the engine is warm or at operating temperature or all the time even when cold? In older engines, a 'bad ignition coil' would fail when the engine warmed up and would not start again until cool or at ambient temperature.

23 hp Kawasaki FH680v engine losses power when engaging pto!

We had issues in the UK with issues like this, they would blacken and soot up the plugs and start to run on on cylinder, there was an internally vented carb rather than the externally vented carb to cure this.
