If your receiving power at the PTO clutch and it is the correct voltage ie. 12vdc then you will need a new PTO clutch assembly.

SOURCE: motor stops when the pto or cutting blades are turned on or engaged.

you most likely have a bad safety switch. there is one under your seat,one on engagement lever for blades,and probably one or two more in other places.start with the one under your seat by unplugging it and then going ahead with normale start up and implement engagement. you will have found the bad switch when everything works as it should.replace switch if you feel its necessary or just leave unplugged. it will not affect performance or longevity of the tractor

SOURCE: PTO does not engage

if your belt was tight when you finished installing it and all the pulleys that it went around are free turning by hand and lining up reasonably well you should be ok.
to the clutch
are you good with a volt meter 12volts dc?

Find your connector close to the clutch
unhook it from the clutch
take your volt meter and engage your red knob (Have the key on and parking brake applied)check your voltage to the connector
Do you have 12volts dc?if so your clutch should work if not you need to trace the wire back to the red knob
check all of your fuses check all of your safety switches.

Or have a 12 volt source (a battery )and hook it briefly to the connector you found directly to the clutch connector pos. and neg. from your battery you should hear an audible CLICK if so your clutch is good if not you are losing 12 volts back toward the red knob
this is the best way to check the clutch while it is still on the machine.
if its the bad clutch get your wallet out they are expensive.
to remove it unlosen center bolt on the crankshaft
remove or move belt guards out of the way and whole assembly should slide right off, note any shims and spacers that may come down with it and their locations
put back the same way it came off and tighten center bolt to 55 ft.lbs.
goodluck

SOURCE: Blades won't engage. OK-I need a pto clutch

A switch should only be about $25. Before you spring for a new PTO assembly, take your switch out and take it to a shop and have it tested. I may just be a bad switch. Don't bother taking it to Sears though. Take it to a shop that works on Husqvarna and/or Poulan Pro. (Both basically same as Craftsman). DO take the model number from under the seat with you.

SOURCE: PTO will not engage blades on riding mower. The

Using a test light or volt meter, check to see if you are getting a full 12 volts at the connector where the PTO plugs in. If no voltage present, locate the fuse for the PTO and check it, also check the PTO switch to see if it is working. You can turn on the ignition switch to the run position, don't start the engine, and turn the PTO switch on and off several times listening for a clicking sound. If you hear it clicking, have someone sit in the seat and start up the engine, while it is running, observe the PTO clutch and see if it spins when turned on and if the belt turns with it. If none of this works, post a follow up and include your Craftsman Model number. I will look it up and see if I can find anything else we might be missing

Ariens 1742- blades will only engage while moving. Once you bring arms to neutral the blades stop.

The problem likely is with the SEAT/PTO RELAY not remaining energize. Look for open or disconnected wire (PURPLE) from the relay towards the ignition switch.

See wiring diagram;

John Deere Z840A Z-Trak mower. Why does engine die when PTO is engaged?

A possible cause is an open seat switch (operator presence). Locate the switch under the seat & unplug the switch from the harness. Place a small jumper wire into the female socket leads to the wire harness. If the PTO engages without engine shutting down, replace the seat switch.

Check to see if the mower deck is plugged or a piece of wood/debris is wedged between the deck and a blade, or some wire/rope is wrapped around a spindle. If the blades don't turn by hand, it'll stall your engine when the electric PTO clutch is energized.

Lastly, a discharged battery will cause an engine shut down if there's not enough reserve when the PTO is engaged. Measure the battery voltage with a meter. If the voltage is below 11.5 volts, you may have to replace the battery.

I have a ariens zoom 1540 mower it runs fine but the blades wont engage to mow. It worked when i put away after last mowing and 2 days later it doesnt. Ive checked the wires off pto switch and they seem...

You've checked the wiring to the PTO and it looks OK. Does the PTO engage when the switch is thrown? Do you have a multi meter , so you can trace the voltage to the switch, from the switch to the PTO. You also should check the safety switch (s) which will prevent the PTO from engaging if there is a faulty switch. And it could simply be a fuse that has blown.

42 Gear model mower blades won't engage

You haven't said if its an electric clutch or manuel so I presume it is electric and controled by a switch(PTO) on the dash 2 reasons.
1 one of your kill switches is faulty example: seat switch which is in an inline circut with your PTO switch could be the problem or a fuse or a bad PTO switch, it usually is the seat switch but trace the wires down from the PTO switch
2 you could have a faulty electric clutch which is under the motor attached to the crank shaft. check the plug in,Does it engage ?sound of a large click and if it does that means the clutch has to be adjusted using a feeler guage.

Cub cadet pto won,t stay engaged

Sounds more like a PTO clutch failure, rather than the switch. The clutch is mounted on the engine shaft, between the hydrostatic drive pulley (nearest the chassis) and the mower deck belt pulley (farther from the chassis).
Since it's an expensive part, make sure the problem isn't in the switch or wiring first. You could do that by probing the wires to the PTO clutch with an automotive test light - they are inexpensive and handy. Clip the ground wire of the test light to the chassis, and probe the hot wire to the clutch (it's the one that doesn't connect to ground) when the engine is running and the PTO switch is engaged. Obviously a helper has to be in the seat, and you should be careful doing this. If the light glows brightly, and the clutch doesn't engage, you definitely have a bad clutch. Good luck! Please rate my answer if helpful, thanks.

RE: Lawn mower blades will not engage

This sounds like a faulty ground condition, the PTO clutch requires a ground provided by the chassis wiring harness to function and a ground for the ignition switch to kill fire to the coils. The other components work as they should because the voltage regulator, fuel shutoff solenoid and starting interlock system have their own grounds. The ignition switch in these mowers is a large round plastic switch not capable of grounding itself, it should have a black wire leading from the terminal marked "G" on the backside of the switch.

to diagnose a faulty ground you'll need a basic 12V test lamp:

Unplug the switch and and install a the test light clip on the positive terminal of the battery, probe the ground wire in the unplugged harness that corresponds with the "G" terminal only. If the ground is good the lamp in the test light will illuminate brightly, if poor or faulty the lamp will not light or be noticeably dim.

Further verification of a faulty ground or failed PTO switch can be tested at the PTO Clutch harness, turn the key on, engine NOT running, and pull the PTO Switch to the engage position, with the test light clipped onto the Negative Battery terminal or chassis, back probe the connected PTO clutch terminals. If the PTO switch is good and the ground is good then Only one terminal will illuminate the lamp, if both wires illuminate the lamp then the ground is faulty, if no lamp illumination then a loss of power is suspected, check the terminals on the PTO switch and Ignition switch for power.

Typical Ground termination locations are on the frame near the rear of the tractor frame, above the transmission, in the steering column area and near the solenoid, check for a loose or corroded eyelet terminal, broken wire, or a missing fastener in these areas.

Ariens ezr1742 mower blades do not engage....noticed after went over a stump.

The common cause of this problem is that one of the safty switches has come dis-connected or has failed since most every newer mower has a electric clutch controlling the mower deck PTO there are safties bilt in under the seat and in other locations to make sure everything is ok before the blades engage, easiest way to test this is to run a jumper from the positive post of the battery to the input wire on the electric clutch assembly making sure all other wires ade dis-connected from the clutch and see if the blades engage if so then usint a continuity tester check all the wires and switches to this item to check for a faulty switch or broken wire.

Arien 34- Blades won't engage

This mower has an electric PTO on it. I had a Scag and the electric PTO clutch went out on it. Not the cheapest things to change but easy to do yourself with some basic tools. Also, before running out and getting a new one, check the wires to it and to the engage/disengage switch. You may have a bad connection.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/matthew_d24b835e574ef6ca
