Pto clutch noise

New clutch, washer is between block and clutch correctly. But when I start the engine the clutch starts smacking the post that keeps it from spinning. But it would break it off if I let it run. Why is this happening? It would spin the blades no problem but the post would break.

Check your mower deck spindles and belt. If belt is slipping at all the PTO will not engage.

SOURCE: PTO problem on a model

I would be looking at the ignition switch....but before replacing it I would be looking for a friend with an electrical meter and checking the wiring for power coming out of the switch to the cluthch, this way you can narrow it down positively before buying parts.

The power take off starts slipping and cuts off after it runs for a couple hours, what is the solutions to my problem

If you are talking about an electric PTO system, then there are two possible causes. The first is voltage drop. If your alternator is not charging the battery correctly, the available power to operate the PTO Clutch will drop below critical level. If you have to keep putting the battery on charge, this is almost certainly the cause.

The second possibility is mechanical failure of the PTO clutch. One of the most common clutch failures causes them to overheat and when the temperature increases, so does the electrical resistance.

Try this test:
Park the machine on a flat, level surface, switch the engine off,lock the brakes, remove the spark plug lead then remove the cutter belt from the engine pulley.
Now try to turn the PTO pulley on the engine. It should be firm to turn and you may hear/feel a slight grinding (this is normal). Next, turn the ignition switch to the 'run' position (NOT the start position), then turn the PTO switch to the ON position. Reach back under the machine and try to turn the PTO pulley again. This time, it should feel much heavier to turn because it's now connected to the engine shaft. It should turn smoothly for about 3/4 of a turn either way. Most importantly, you should no longer hear/feel any grinding. If you can still feel grinding, it means the PTO clutch has had a mechanical failure. In some cases, the fault can be rectified, however it is not generally recommended as a D.I.Y task.

I replaced drive belt on troybilt mustang rzt shortly after electric pto clutch stopped engaging

Moist likely you failed to reinstall PTO clutch correctly as it sound the anti-rotation device wasn't installed. When you started the engine it would spun pulling the wiring apart. Hopefully just connector came part; otherwise, you might need to purchase a new PTO clutch assembly.

Blows a fuse every time I engage the cutting deck

it is not supposed to start unless some one is in the seat
now for your problem, if engaging the cutter deck blows a fuse then check the wiring for a wire that is cut or shorting out on a lever that moves when the cutter is engaged

PTO clutch making a loud clicking noise.

I really need some more info from you...but here are a few things you should check? Since it clicks with or without the has to be an electrical issue! Check the switch, look for broken wiring, or loose connections. Another thing it might cause this is the battery or the charging system! If there is not enough voltage to hold the clutch engaged or what it is getting is shorting out then that would be your culprit! I hope this helps! "Be Easy!" Neighborsboy

Remove clutch

I'm assuming you're referring to the PTO clutch on the bottom of the engine shaft. There's a 5/8" bolt that goes up through the clutch into the shaft. Remove it, but then turn it back in about 10 turns and use a wheel puller to start getting it off. You might have to c-clamp the PTO/clutch top and bottom together to get both pieces off. Once the assembly starts coming down the shaft, you can probably remove the wheel puller, remove the bolt completely, and pull the PTO/Clutch off by hand. Be sure to unplug the PTO/clutch before removing it. Also, many of these have a spacing washer on top of the PTO/Clutch that comes off in the process. BE SURE to put it back on before replacing the PTO/Clutch. DO NOT hit anything with a hammer to try to break it loose - you'll most likely NOT get the part off and most probably WILL damage necessary parts.

Wheelhorse 314 engines dies when pto is engaged

I am assuming you have a manual PTO clutch since you did not mention a PTO switch. The starting circuit generally is a series of switches wired in line (series) with each other. You have bypassed the seat but there is usually a switch for neutral, PTO, oil level, and clutch. You will need to trace the wires from one to the other to find the problem. If the seat has a double switch (3 or 4 wires) it is wired through the PTO switch which may be a double switch to short out the ignition so that part of the circuit should stay open to operate. If the oil level is ok and the oil has been changed as recommended you may better consult a Wheelhorse service person. Bypassing the switches is for testing only! I DO NOT RECOMEND LEAVING ANY SAFETY SWITCH BYPASSED. Any defective or out of adjustment switch should be replaced or corrected.

I need to know where the fuse is located

Hi and welcome to FixYa, I am Kelly.
Look inside the cowl on the same plane as the clutch / brake pedals. There should be a rectangular fuse recepticle with a 20 Amp plug in fuse. Just look up and down inside the cowling using the clutch / brake pedal as a reference point to start searching, You will find it. If the fuse keeps failing you will have to start chasing clutch / brake switch wires, PTO clutch wires, and Seat switch wires. Most of the time the failures are at or near the switches. As for the PTO clutch... belts over time slap the wires of the PTO clutch and either chafe the wires or break them at the PTO clutch.
Engine overspeed on this model also causes the engine alternator to fail the fuse.

Thanks for choosing FixYa,

CubCadet 1554 - won't start!

If you hear the PTO click when you turn the ignition on, sounds like the PTO button is pulled out like you were engaging the blades. The engine will not start if the PTO button is pulled out....

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
