Hey Pat. Right now my transmission is being reassembled by hand and I expect it back in a week or two. It is a long drawn out story but my dealer has been phenomenal. Mahindra just so happen to drop a demo tractor off to them to put out in the field (6065 with PST) and I already have 30 hours on it even with the rains we have been having in VA.
Long and short; the noise in the video appeared, tractor went in to shop and they replaced entire PTO internals under warranty. Tractor came back with noise and over the course of 10 hours the hydraulics were overheating and the clicking was getting worse. Tractor went back in and corporate came out to evaluate... heated discussion in the garage and the mechanic tore my tranny apart (HST) and found bad bearings (gritty feeling) - he is also shimming everything to the center of tolerance - this is what the mechanic believes is causing the problem.
Not sure, but I will find out when it comes back.
I see you PM'ed me with your phone number and see you are in Texas. I'm in Virginia and will give you a call in a few hours so we can compare notes... but the one thing different with mine is no other tractor on the lot or other customers tractors made the same noise as mine. Every 1/4 turn on the shaft (by hand) you could feel and somewhat hear the 'click' - but running the PTO with nothing connected you could REALLY hear it. It was not a slight sound, but VERY noticeable.

UPDATE -
The drivetrain was re-assembled (two weeks ago) with new bearings and seals, tested and still a PTO click. The dealer is still working the issue and actually used a stethoscope to pinpoint the origin of the noise; they believe it to be a clutch pack in the HST, so part has been ordered and it goes into tear down again. They believe the problem is in the clutch pack and the sound is reverberating to the output shaft because the noise from the stethoscope is very distinct in this area - not before it, but right at it and gets louder as they move the stethoscope back.
Even the owner was out there laying on the shop floor listening to help isolate the issue. I am amazed at the above-and-beyond attitude and service they are putting into this. Granted they are getting paid major $$$ from Mahindra on this and the cost will be nearly 2/3rd's of the tractor but in the end I know it will be right.
With the dealer digging they found some interesting things regarding the 2555 and clicking PTO; 40 units in the US, 27 in Europe and 20 in Asia have reported the 'clicking' PTO issue. They did not say HST only, but I can only draw the conclusion. TYM has come back and said 'this is an acceptable noise tolerance.' My dealer will not accept this because they know it is an issue because they have sold over 50 2555 with HST (cabbed and non-cabbed) with no issues. Out of the 50, 5 of them are cabbed and run a 7' Mahindra HST cutter like me and have zero issues.
The dealer is carrying the torch with an open ticket from Mahindra Corporate because they (dealer) want to isolate the issue, correct it and shove it up TYM's blow hole. From what I understand the dealer's owner has blown up the President of Mahindra a couple of times because they are not pushing back on TYM because this is a problem which will eventually manifest into a catastrophic failure for customers whose tractor may be out of warranty.
I think the incentive on my end is I am demo'ing the 6065 (which might replace the 5xxx line) and providing feedback on a weekly basis... I get a call once a week from the Mahindra Regional Rep (Graham H) and we chat about the tractor - they even took a suggestion for the PTO selector detent setting, re-engineered it and are sending out the replacement part to be installed and for me to test. I've just crossed 40 hours and expect to get more run time on it this weekend with spraying and more cutting. The dealer has told me to run the snot out of the demo unit because I have some pretty steep rolls in some of my fields.
I am sooooooo glad I picked the dealer instead of having blinders for a brand.

UPDATE (yet again for those who are following)
The clutch pack and seals were replaced in the HST, tractor assembled and tested. As soon as the PTO was turned on 'click, click, click, click, click' during rotation - same issue.
I was immediately called and it just so happened I was 3 miles from the dealer so I decided to stop in. I sat down with the Sales and Service Manager and we started to talk. At this point the three of us are scratching our heads and their lead mechanic is completely baffled. The dealer is starting to draw up the paperwork for a replacement but I asked them to get me the name and number of someone @ MahindraUSA corporate so I can vent... I contacted customer service to get the issue placed on file on April 17th and received an email response on April 26th, with no follow up - I was upset to say the least with customer service.
They gave me the number to the VP of Marketing and we had a bit of 'Come to Jesus Meeting' over the phone. A statement was made by him 'maybe your dealer does not know how to correctly diagnose and repair the problem' - I immediately took offense and the entire conversation, with this statement, was relayed back to him in an email, as well as the dealer. I also pointed out that if their corporate engineer who flew out from Texas to look at my tractor could not diagnose and fix the problem maybe they should look internal.
I immediately got passed to the head of Corporate Customer Service and it looks like they are working with the dealer to replace the tractor. With all the information I have received and problems reported from the TYM rebranded units I told him if I had another 2555 delivered or any TYM re-branded tractor delivered to my property and I had the FIRST issue with it he and the VP of Marketing would be getting calls on their personal cell phones from me directly. It looks like I will be getting another model equal to or better...
We will see how this all plays out but I am soooooooo happy I picked my dealer above the brand. The dealer is hitting corporate from their side and I am squeezing corporate from the other.

The cab is pretty much needed as I can mow in the heat or rain, plus it keeps the **** bugs off of me and dust when I'm mowing, raking the driveway (+1000"), horse paddocks or arena. Plus it's nice to have in the winter when I have to drop a round bale or any of the chores above. .
Either 2wd or 4wd, it doesn't matter. This is the first time any dealer has dug into the noise issue, and not all 2555's do it. There are reports and TYM keeps saying it's a nominal acceptance.
I can overheat the hydraulics in less than an hour of mowing and the PTO and transmission has been rebuilt by hand, and the mechanic is very well known in our area. Even the wiz-bang engineer from Texas is stumped.
I've told the dealer, VP of Marketing and lead of Customer Service i do not want a TYM made tractor to show up on my farm... researching this more I am finding more and more issues with either the 2555 or the TYM T554, they can keep it because when my tractor goes down maintenance on the horse farm piles up and we come to a standstill. The loaner is a short term stop gap and works great. I'd tell them I'd keep it but it's an unreleased model being tested in a few markets.
What problems are there with the T554. It seems most issues with the 2555 are engine related. It is well known that the 25xx series are TYM made machines with Mahindra engines. Most issues with the T554 seem to be a fading display. TYM made the previous 10 series for Mahindra since the early 2000's. They do have some issues, but all manufacturers have issues. What do you want them to replace the 2555 with the 3550. Big price difference there. A much heavier and lower hp to weight ratio. Good for some things, not for others.

I am watching this thread closely, as I have a 25-series, but not HST (2540 shuttle). It has run perfectly for the first fifty hours (gets serviced this weekend), and beside the hydraulic fluid being kind of hot (and the level was very low when the dealer returned it from installing the BH—shame on them), there have been no issues whatever. I have run a Mahindra finish mower and a Woodland Mills stump grinder (which I don't recommend if you don't have HST, but I'm getting by with it) off of the PTO for 15 hours or so.
From what I understand the T554 (TYM) has had reports of clicking PTO, but do not know the documented numbers. Mahindra has given me the reported numbers (listed above) about the clicking PTO, but are going off of what TYM says for resolution - which there is none... I am unsure if there are any of the reported numbers experiencing overheating in the hydraulics. I am not pushing the tractor hard by any means - the overheating only happens when I am engaging my cutter. From what the USA rep has told me this is the first time a dealer has actually dug into the problem of the noise, but they also know my issue is well beyond a noise (the clicking sound)
The replacement, that is the million dollar question. If there was something in the 4000 or 5000 line with a cab I could get within specs of the engine/pto horsepower of the 2555 I'd be listening to what they had to say. Since there is not this only leaves 2 options at this time; 3550 or mPower 75, and yes there is quite a bit of price difference. The head of customer service is working with the VP of Marketing to 'make this right', so as of right now the jury is out to see what they do. If they finalized the demo I am using (6065 - yet to be released) I would gladly take that as I have put 66 hours on it in the past 2 months.
Interesting comment made by the head of customer service; when we were talking about the issues I was having with the 2550 and the chassis/drive-train (minus engine) being TYM he said 'yes, this being a TYM tractor is not passing the sniff test' - This is an open ended comment for sure and I can only speculate what this means.
There are PLENTY of 2550's in the field right now with zero issues but to be brutally honest I am extremely gun shy of the 2500 line.
I looked at that tractor, and the cabbed 2538 but needed bit more oomph as I have 65 acres, cutting 40 of it. I have a lot of 'rolling hills' and the 2555 does great up until the Hydro's heat up... then I am dead in the water until it cools off. I think what may happen is once I receive a replacement this one will be trucked back to either their assembly plant or Texas for them to isolate the issue. I would like to see them fix whatever is wrong to prevent others from having the issue but my main concern is I, and the dealer, knows the sound is not normal. Eventually whatever is causing the sound may or may not grenade and Lord willing if the tractor is out of warranty.
The thing that cracks me up about all of this; the dealers cannot order a complete transmission or axle/pto as an assembly, only the parts to rebuild.
Like I said there are many happy 25xx owners out there and they are a great machine but my experience with it has left me sour. Not to the Mahindra tractor line or my dealer (dealer is phenomenal) but to this specific series.
Iv had one do the same thing... he was trying to mow with a 10ft mower and that tractor in HST just wont handle it... swapped him out with a 5555 and solved the issue... this was dealing with openstage tractors though. still I don't push the model very hard... now the 2545 and 2538 we don't see much issues with... also the 2565 and 2555 shuttle have hardly the issues...
A 10 foot mower is wayyyyy to big for a 55 hp HST tractor with extra hp loss with the HST. It seems that all manufacturers have more problems with HST machines than the gear machines. Do you think he would have had the same problem with a gear 2555? As for the 2555 not up to snuff. It is the same tractor as the 5010 with a different engine. That is it. Not sure if TYM made any other changes to it. There are a lot of 5010's out there. What does Mahindra have to say about their numerous issues with the EGR on their own engine? Have not seen this reported on the TYM with the Yanmar engine. There is some reason why it is clicking and yes someone should forgive out why and fix the problem. If I was TYM I would bring several back to North Carolina and diagnose the problem, fix and let corporate know and get better parts. The clicking does not seem to effect the performance of the tractor.
I am running a 7' Mahindra mower, and according to Mahindra it is a recommended setup for a 2555 HST. A 10', no wonder it is overheating! The 7' mower blows through what I am cutting with zero issues until it overheats. I have ran a broadcast spreader on the back and it still overheats so I know it is not the load of the mower.
I know the EGR kits are coming, that is one thing one of the reps told me - they are still building up the parts supply to get them out.
I have also heard of others who have the 'click' and experience zero issues, just the noise.
From what I understand, the 2555 is a TYM with the Mahindra Tier IV engine.
Id be well willing to bet the shuttle would show great improvement over the hst performance in pasture pto work
HST tractors have always had a lot of issues with hydraulics getting hot. I think your issues would be solved with the same tractor with a shuttle transmission.
Agreed.
Final Resolution - Mahindra has replaced the tractor with a different model. :laughing:
For the past 3-4 months I have had the Demo 6065 and it has handled every task thrown at it. Once they refine a few things they should be coming out in the future.
Mahindra has since sent out 2 or 3 different engineers or technicians to the dealer so they could re-shim/replace bearings, seals, gears whatever you can think of from the transmission all the way back to the PTO with no resolution. They even had it sit outside at idle, PTO engaged with nothing connected to it, stub shaft spinning and after 60 minutes you could not touch the rear casing because it was too hot.
This has stumped the company so they upgraded me no questions asked with no money out of my pocket for my time and trouble. Plus providing them valuable feedback on the demo pre-release model has helped them add needed changes before they go into manufacturing.

Neither. Between my bitching at corporate, them (corporate experts) not being able to isolate the problem and my dealer talking to them, Mahindra delivered a brand new mPower 75p on Monday.
After reading some of the comments above being in a shuttle this is probably true. The cutter is a Mahindra 7' HD - and Mahindra swears up and down the 2555 HST can handle it, and it did for about an hour until the hydro's overheated... but they overheated without anything connected to it so I really cannot say, but I would speculate the Shuttle would be no issue. Now that I have ran the 6065 with PowerShuttle I kind of like it. The 75p does not have PowerShuttle, just SyncroShuttle but I was using the clutch pretty exclusively in the 6065 so it is not much different for me.
We had some long talks about what I needed in the tractor and requirements, plus I was demo'ing the 6065 and provided a TON of feedback and did maintenance to it myself as needed. There is an issue with the PTO popping out of gear and through some thorough explanations on the phone they redesigned the degree of throw in the lever to provide a more positive detent. Plus where I am at, my property has some serious grades to mow and they did not have a unit out there to test braking on hills. Courageously I did some tests for them and provided feedback - it is an incredible machine and should be a winner for them.
Overall the experience has been a HUGE educational process for me and I got to know my dealer REALLY well! :laughing: I stand by the fact of pick your dealer first because they are the ones who went to bat for me and pushed for the mPower 75p.
