I was driving the x540 across the yard (not mowing) when I heard a strange sound. The next thing I know there are sparks coming out from under the tractor. I shut it off, looked underneath and found that the electric clutch had come off. And then I found the retaining bolt and saw that it was broken.

I took the tractor to the dealer and he told me that although not common, he has seen this before. He believes that sometimes they come over torqued from the factory. They are a real good dealership and I trust them completely but it just seems odd that it would take 2 1/2 years for an over torqued bolt to break. :unknown:

I believe so. I still have a year left so no worries in that regard. I have to wonder if this might not related to the "full throttle to engage the mower deck" phenomenon. I have always found it strange that the throttle had to be fully open to engage the deck. Kind of runs counter to the pto driven implements on larger tractors where you engage the implements at low rpms. Add to that the various threads talking about how tight the belts on the 54c deck and it does seem curious.

For sure not common,Google didn't produce any other bolt failures besides yours. Probably did occur as the tech explained. I doubt JD would use very strong bolts on something like that,and it's very possible it could take that much time to finally fail. On the other hand,it could have snapped the moment it was over tightened at the factory. Just one of those "flip a coin" things.

As Brian asked,is there any possibilty that JD will take care of this?

I believe so, after all I am still in the warranty period and it is a mechanical failure. "4 years or 500 hours". Again, this dealer has been excellent to deal with so I am not anticipating any problems.

I almost bought a x540 but went with a MMM instead and did quite a bit of research looking into them (my plan was to buy a used one from Machine Finder so I had concerns) although I don't have any links I do recall an issue with the clutch that was posted on many forums/reviews and also folks actually rebuilding them on YouTube vids.

I never engage the deck at full throttle. It says that in my X748 manual also. It never made sense to me. I think if your RPM's are up enough not to bog the tractor down too much you will save some wear and tear on the clutch.

Problem is that unless the tractor is at full throttle when engaging the deck it will stall.

Interesting. I can flip on my PTO on my X320 at idle and it will not stall, nor bogged down. I believe the manual on my X320 says to engage the PTO at mid throttle, if I remember correctly.

I guess if I have a complaint about the X540, this subject would be it. I can engage my MMM at about half throttle but the engien spits & sputters. The operators manuel does state:read: to move the throttle to fast position and then engage MMM.:thumbsdown: It sucks I know but I will learn to live with it.:drinks:

What size is the deck on your X320? Mine is a 54" and I thought that maybe that was the reason for the extra "drag" on the motor. I had a 42" Husqvarna and I could engage the deck at idle with no problem (15 hp Kawasaki motor).

Interesting because I did just the opposite. Got a good deal on the 540 and have been real pleased so far. Just talked to the service manager and he said that they replaced the clutch. Also noted that the voltage regulator was off so they replaced it as well. All warranty. :good2:

The conclusion ....

Service Manager called last week to tell me that the 540 was not ready as they were still waiting for a voltage regulator (they determined that mine was over-charging). They offered to drop off a loaner to me which just about blew me away (they are 50 miles away). I declined and mentioned that I would be up at the beginning of the week. Today I went up, it was ready, and I brought it home. New clutch, voltage regulator and battery .... all under warranty.Aand the best part is that it works better than ever. I can now engage the deck at 1/3 throttle and it kicks in real quiet.

The service from these guys is top notch. They will get all of my future business, needless to say. :good2:

x540 clutch problems

Hi everyone, new cust, new to site. I have a problem with my x540 electric clutch will not engage by pto, but will work if i bypass pto switch, tried new pto switch, bypassed all safetys for testing purposes, tried new control panel, checked wiring continuity, baffled as to why blades wont work with switch, only if 12v sent to clutch manually it will work,. Any thoughts or is there something im missing?

Thanks in advance

I had a very similar problem with my gt275. I found the voltage regulator to be the cause. You might look at the specs in your service manual to find what yours should be running. If I remember correctly , mine was 28 volts @ half throttle.
