Hi All,

Last year the PTO clutch locked up and because of this, I couldn't start the engine as the engine wouldn't turn over. The repair shop nearby told me to order a new PTO clutch and I did and they replaced it. I only used the PTO for 19.1 hours this year and the mower stopped again while running. The repair shop said it's the same issue and that the PTO clutch has locked up. Briggs and Stratton's authorized dealer nearby me won't cover it under warranty as they weren't the ones who removed it from the mower themselves.

I'm really surprised that the clutch would have an issue in just 19.1 hours. I tried removing the clutch as well and I couldn't get it off and the shop said it wasn't easy removing it as well.

A new clutch costs about $430 and I'm wondering if there was an issue during installation that may caused it or there is perhaps a different issue with the mower that led to the clutch getting locked up. I'd hate to have this expensive repair done only to get the clutch locked up again.

Pull the wires " connection " Off the clutch, Start your mower - this will eliminate the pto from your machine, if all goes well , let us know and we'll go forward from there, I've never seen a PTO locking up in all my previous mechanical issues. ----------- especially 2 times on the same machine ,,,,,,,,there is something else going on in my opinion

So the clutch had to be completely removed, otherwise the engine wouldn't turn over.

The clutch has electric engagement so pulling the connection off takes it out of play , if it still binds up the engine so it will not start,,,,,,,, either you have a battery or connection problem or possibly an engine problem.
It's possible the clutch is causing the problem but to be honest if the blades are not in a loaded state , ,, like cutting a tall bunch of grass it should still start and run.
What you're saying is the engine is fine with no clutch in play so the engine sounds like it's fine, In my opinion you should still be able to start the machine with it stuck in the engaged position

Lets start with the brand on exact model of mower so we know what you are talking about. At this point we know it is a mower with an electric clutch. What engine, what mower.

The mower is Snapper Pro S200XT Professional, Model # 5901280
Engine is Briggs & Stratton, Model # 49T877, Type 0010G1, Code 160107YG. Engine Serial # 16 0107 YG 97606
The clutch Part # 5105090YP

The problem is similar to what is shown in this youtube video -

I would be either suspecting the charging system is overcharging causing coil overheat possibly damaging the bearings or overtorque of the crankshaft bolt causing a side load on the bearings causing failure. But could of just been a faulty clutch. been having issues with parts not working out of the box lately.

As IL said it can be a number that cause the bearing to fail so early. You have apparently the 61" deck which use the Warner 5218-134 PTO clutch. I would be installing the Xtreme X0216 clutch this time which a much better clutch. But voltage must checked and clutch must be burnish in. PTO retaining bolt is torqued to 55 ft-lbs.

From Xtreme installation sheet.

So can you suggest how this can be tested? Should I check voltage at a particular location to see if it is over charging? And what about overtorque, is there anyway the repair shop can test that?

This Clutch is half the price of the one by Briggs and Stratton, but is there any way to check if it will fit the mower?

I am coming up with the 5105090YP superceded from 5105090 from the 5100084 which is coming back to a X0245 for a replacement for the 5218-221 warner clutch. But the 5105090 is showing the 5218-134 for the X0216. But if you put the S200XT into the xtremeope search is shows the x0245. But both show the same pulley diameter, same shaft diameter, same rotation, and same torque. So maybe interchangeable.

See testing instructions in the post by Star just above yours for testing procedures.

Did even read the Xtreme instruction I posted about testing the voltage?

As for the torque you can't really test that after the bolt been installed for awhile as it develops a static bond that throw off the initial torque readings. But way you use a torque wrench to check the installed torque. Most torque wrenches out there only does RH toque readings so you can't the loosening torque as that is a LH operation.

Ok, I assume I will unplug the PTO connector, turn on the PTO switch and then measure the voltage. I'll let the repair shop know. Hopefully they know more about this

Looks like the original clutch used on that model per PD was the 5100084 which appears to be the 5218-221 but the superceded number of 5105090 and 5105090YP are the 5218-134. Stens is crossing the 5105090 over to 255-827 or 5218-221. And it looks like Warner electric is showing the 5218-221 as a replacement for the 5218-134 So from that I would gather that the X0245 and the X0216 are interchangeable.

I couldn't even get Warner electric website to find either one those PTOs. Are using a different site than https://www.warnerelectric.com/ ?

All I can go by is what is on the Power Portal site and go from there. It like one of my members on another where Sears insists his mower has a manual deck lift when he has an electric deck lift.

Here is where I found it at. https://www.warnerptodirect.com/shop/pto-clutches/5218-221

Thank that link I get the info on my system updated to supersede 5218-134 to 5218-221. I will also bookmark that website of Warner, just why they don't link it is not known.

I also didn't have website in the vendor's file here but do now.

Thank you for the research. I was unable to follow how you went from Part # 5105090YP to a Warner PTO 5218-221. So does it mean, Warner PTO just makes replacement PTOs at a cheaper price than the original equipment manufacturer?

I did notice at some sites (https://powermowersales.com/ferris-5105090) that had 5105090 and 5218-134 side by side.

So should I go ahead and purchase this https://www.warnerptodirect.com/shop/pto-clutches/5218-221 and give it to them at the repair shop.

Warner is the original equipment. It is just that Briggs/Snapper purchase them from Warner and then mark them up.

Wow, what a big mark up. Warner PTO 5218-134 is priced at $159.89, while Part # 5105090YP from Briggs & Stratton dealer is around $430. Thank you for you help. The mower is currently at the shop, but I will certainly do the voltage test or request them to do it as well.

Just two more questions. Can you please explain how you were able to find that the 5218-134 is compatible with 5105090YP, and also you mentioned earlier that you'd be installing Xtreme X0216. So is Xtreme another PTO manufacturer as well? Thanks

Lets start with this diagram for the answer to your first question https://www.partstree.com/models/s-...ton/engine-pto-group-s-n-2017681136-below-34/

Scroll down to item 14A in the list on the right and it shows Warner 5218-134.

Second Xtreme is an aftermarket PTO clutch manufacturer that many consider the top of the line PTO clutches due to upgraded electric coils, replaceable bearings, and the machined pulley

Thank you so much for your help. I've ordered (https://www.warnerptodirect.com/shop/pto-clutches/5218-221). I'll have the repair shop put it on and then let's see if it breaks down quickly or not. Hopefully not. They had to pry off the last one, it wouldn't come off. I had tried taking it off myself at home, but I was unable to.

Make sure they use antiseize compound on the crankshaft when they install the new clutch.
