I should report to the public, I have been in extensive contact (messaging) with a few members of this and other tractor forums. This info in reality should of been posted (instead of private messaging) as some may have learned from this banter. In a nutshell... -- I tested the possible fuel...

So at this point and time and as much as this has been baffling (to not only myself), I would not eliminate injectors. I can order a set of 3 for about 4G, and if I knew this was definitely going to solve the problem, I would do so. But what a waste if it did not fix the issue and I have 3...

I can push snow all day long, no issues. Change to July heat and mowing for an entirely different story. Told repeatedly above. Sad it's been this long with no real answer.

@FrankJG Yes, Thank You for updating us on that. I'm interested that if in your real life usage (again) it really appears to be solved, so please keep us updated. My warranty is now out, but, this issue was documented (and in shop) while still in warranty and they did or could not resolve and...

Ok, I get the fact that injectors and extended run times with heat is or was a reach.... BUT!, when I first contacted my dealer about the problem, I talked with the mechanic (right in the shop area) and the first words he said was "injectors I'm thinking, there is a recall on some MF models and...

@FrankJG and others... Throughout this thread plus the mytractorforum thread, injectors have been mentioned several times including by myself, but we never had a definitive dealer conclusion. We kinda did, but that owner had two things done including injectors, so we never could pinpoint it, and...

With this power-loss issue, I can restart my MF 1740M at anytime, even after the direct power loss. If I let the engine cool down like more than an hour, I will get full power, but for like a much shorter duration than the original start time, but full power does come back albeit for maybe 10...

Just an over-the-Summer update.... It was bad all summer (meaning after 30 or so minutes of mowing with the A/C on) it would have this power loss and no throttle response. HOWEVER!, now in the early Fall mowings with no A/C and much cooler temps (I actually have the back window open for air...

Hey Frank, Yes, get this documented by your dealer and if it then goes beyond your warranty then you'll still be covered. On your last paragraph, it's not you doing something wrong, there's clearly a problem and just as you say, it clears up the next day until it gets worked hard again for an...

Well, on the part of if this is a big trac/mower combo for just 2 acres?... Well, to average outsider outsider I would say yes, but to someone that can use the tractor, basically for other uses/tasks (that a small lawn-tractor can't do?), it's just a great choice, especially if you want to cut...

@567Chief Totally feel you on your lack of confidence. Maybe it will come back "IF" the replacement of Injectors was the issue. Trusted time in the seat may build this up. On my last tractor (prior to this 1740M), I had a Case International and in 16 years of ownership from brand new, it saw...

Okay, I'll put mine out there (if it hasn't been clear enough)..... -> When I turn the (steering) wheel sharp, the RPM's decrease. -> Going up a slight incline you get the drop, actual hills you can get down to creeping speeds at best. -> Taller grass mowing, the same. Beginning of the mowing...

I read that article, TY. Even though that was more "Industrial" equipment and mostly related to heat, our small turbos could have been harmed in a way that they do not operate correctly anymore under "hot" exhaust load temps. I use to be involved in No-Prep drag racing and hot turbos were never...

Thanks for chiming in with this same problem on your 1735M HST. Super glad your dealer has a dyno, and with an interface connection to their Agco diagnostic software; it should be a done deal for troubleshooting once the power loss occurs on the dyno. If and when it gets fixed or resolved...

No smoke from exhaust at anytime. So hopefully injectors are ruled out.

Turbo replacement Con't... And if it resolves, dealer sends the defective turbo to Agco, they can inspect & test to see what failed. Truthfully, they probably already know. If you're not going to be modern slash hi-tech (with trouble shooting these power loss situations), then it's the process...

Yes sir, I know the Turbo's are not cheap. But here's my thinking. Agco must know of this issue by now, between the 3 different Forum threads that this is directly related to, we know others with this exact same issue. And, if that guys 1735M was fixed by a turbo replacement (well he had...

I think a dyno or 3pt hitch/load on the tractor with a dealer interface hookup to the ECM would be the cats meow.

I'm sure he had it fixed and (apparently) with the turbo replacement, like you say he would of continued the banter if not.

Anything is still possible, but to me it sounds hardware related being that we now have other owners popping up with the same power loss and it's a delayed response with them as well. I originally thought and remarked here in this thread that I was thinking injectors. Turbo (to me) sounds...

I just got off the phone with my dealers service mgr (Aleasha). She's looking into what should be our next step. I told her that if we could pre-plan this so my tractor doesn't just sit at the dealer for a week or two doing nothing while Agco okay's the warranty replacement, that would be...

Great thread on what seems to be the same exact problem, and I thank you so much for finding this (not sure how I didn't, but way cool!). Only thing is the OP never replied back that it was actually the "fix". Here's his last post....

Sadly, the Saga continues... I was feeling so optimistic that this was going to be the cause, the grass WAS a tad shorter than norm as I did rush this mow job by a day or 2. I did go about 45mins, albeit I didn't have the A/C on. When the sluggishness kicked in, I took the mower and tractor out...

Yes Sir, if this "is" the problem, embarrassing may be a kind word. It sure is the best answer so far, and it checks all the boxes... -> Higher/heavier loads consume more fuel creating the vacuum quicker than without a load. -> A/C on creates the problem a bit quicker, yes, w the air on I've...

I went out and looked at the fuel tank and cap area. I see the overflow (back into tank) opening but I don't know where or what to look for as far as a vent goes. Is it built into the cap? I see no openings on the top of the cap.

It does make sense kind of, with the tractor setting for an hour or so after the power loss it comes back for awhile, so the tank could of been vacuumed and hence the power loss (or in this case) fuel starving. . This will take the cake if this is it. And literally, I will eat a whole big fat...

I know with a gasser this would be a probable cause, not sure with a diesel BUT I can sure give this a try quite easily! ON MY TO DO LIST! :) Much appreciated and my next Mow will be ~this upcoming Sunday or Monday.

It was stopped completely w no forward speed, level ground (no HST pedal), full throttle and maybe half RPM range achieved. I brought down then to an idle for maybe 2 minutes, then was able to get some throttle response, not full but enough to engage the mower. Then, with the mower up to 540 PTO...

Speaking of the problem, it's been ME showing this loss of power (to my dealer) because it doesn't happen until under work load and around 40 minutes. I also asked if they had a 3pt. hitch [load] or a dyno, but my service Mgr. (Matt) said no. :( UGH! This load tool is what I believe is needed...

Boy oh boy, it sure sounds like you're in the exact same club! Your 1750M is the same model as mine but with 10 more ponies. I was actually trying to originally buy (or order in) this exact model, but my dealers salesperson said I couldn't do an underbelly mower with it. Understood and another...

Beyond what I want to do TBH, if the dealer wants or has the need to "Tee in" a spot so they can monitor this then I'd certainly give the go ahead. But honestly, I would need (or want) a higher level (than myself) to do this especially while it's under warranty.

Understood but no sediment bowl on the 1740M. No inline filter other than the 2 large spin on fuel filters, 1 is mounted low by the right foot step and has a built in plunger primer pump, then the other is up on the side of the engine block. Both have been changed as mentioned.

If that's the case, I did change both fuel filters now twice, thinking originally this was the issue. Not sure how you could ever tell if there an air pocket in there or not, it's just not a visible aspect I could pursue in any workable to visual inspection.

Agree it's not like any Limp Mode I've experienced on other vehicles. So I drought that honestly, and why I never embarked on this in earlier posts. It will mow through 1 ft tall grass like no other, no slow ups, no RPM drops well until maybe 30 mins or so then. So loading the workload up more...

Hi JWR 1. Will do, my dealer has been good to me. And, I have a Youtube channel and have made positive plugs for them previously. 2. I own a laser pointed heat gun, so this would be no problem at all. My concern is that nothing seems like wave like heat coming from anywhere on the engine or...

Fuel Bowl? I know what that is in a gas/carbureted model, but being this is diesel so I am clueless. Can you detail more?

No sir, I told my dealer that we should continue this quest maybe in the dead heat of summer, like when my grass isn't growing as fast and needs almost 2 mowings a week! Still have no hard leads TBH; as to where or what to point the finger at?. We have had a some other 1735M and 1740M owners...

I tried to make it short and sweet. I can't stand informational video's that start out with the guy sipping his coffee, showing his dog and you have to get his life story before you get to what you want. This video is well under the 5 minute mark. Hope it helps show what you're in store for when...

I'd like to add.... My Dealer; American Equipment in Farmington NY has been very good to me!, and, I'm sure if they had the tractor long enough, they'd figure this puzzle out. My conundrum is that it is smack dab in the middle of mowing season right now, and I can't have weeks away without this...

Not sure exactly what they did TBH, other than they updated the ECM software. It could be something "starving or slowing up" the fuel delivery, it's funny as it happens always about the same time into mowing, ~40mins. And on a cold day without the A/C on, it's more like 50+ mins.

Yepper, KJ is my first name. I kept the same avatar. That thread became very interesting to me because that 1740M owner had the shuttle gear drive, and it was happening to his model as well. So deflating as this news was, I felt like we got to cross off the HST causing the issue. I'm not...

I've got some potential bad news... I don't think this Hyd oil change is going to help. So, I also posted this issue on another Forum, and I had this reply... https://www.tractorforum.com/posts/432050/

This may be my final resolution if the Hyd oil change & filters doesn't resolve the issue. My dealer says they want it back, I just don't want another 4 weeks without it, especially in mowing season... hence why I'm tryin everything "I" can do first. You guys have been great BTW! I want to...

Mine is yes, the engine and DT are 5 years and I'm on the inside border of it; barely. So far, my dealer has charged me $0. Including pickup and delivery. :)

In my upcoming video (on the Hyd Oil Change), I'll emphasize and show this bar cutout with the filter sliding thru it. :)

Agree, I did have some metal fragments found in the suction filter. Not sure if this is normal or not? I'll have these images in my upcoming video on Changing the Hyd. Oil in a Massey 1740M (and 1735M, not sure if the 1750 hold true or not).

Man, I hear ya loud and clear! My 1750M is perfectly fine the next day, well at least for another 40 minutes of mowing (And, I no longer want to use the word "hot" as that got some folks on a wrong tangent). I don't mind being the guinea pig, as long as we get this resolved. Yes, please stay...

TH- I have all the old fluid and 2 filters removed. I'm waiting on the vertical filter yet to arrive, it's coming from a MF dealer in Utah, so that shipment to central NY has a few more days to it. I have new the oil but won't fill till I have everything ready. Opening lid, it does look clearer...

I was surprised, I was anticipating my fingers almost getting "scorched" while taking out the oil plug (during in the last few turns). To me as well; Oil did look dark, but maybe b/c I used a white used drywall mud bucket?... used this as it was a tad lower to get under the tractor belly...

So today before my draining, I did the ole 40, had plenty of power during and when the power started to lag, I put her in the pole barn and immediately drained the Hyd oil. I was expecting it to be hot, but it was actually like a very warm shower, like that you'd have during the winter. I also...

Hi, You can remove this horizontal suction filter without removing the subframe gray bar. I have successfully done it. I will make a thread on the entire procedure including step by step images. Give me a few days...

My mind is still thinking; It's weird cuz the tractor was fine for several Months, if not an entire year after that hyd line blowout. Maybe the process would take awhile also? I never saw any milkyness or murkyness in the (supposedly sight) site-glass. It's crystal clear hot or cold.

I concur, I'm changing both filters (and the 821XL fluid) just to be able to rule this out.... I'm barking more up this tree because (insert lightbulb above my head here!) over a year ago, I blew a hydraulic line, one that's right above the lower fuel filter and primer pump area. It went back...

You just snuck in ahead of my post, I'm VERY interested in this Dye! PS, I don't use the term Sight Glass, cuz that implies you actually have sight! So this is a site-glass, it's just taking up space or a site on the tractor!

I'm all for the orange color (cuz these site-glasses suck! lol), I have not seen any milkiness out of my Permatran 821XL, but I may not be working it like that poster. My concern would be Agco trying to deny any coverage b/c of it. My tractor is on the last year of engine/DT warranty however, so...

Hi JWR, No worries, I would never pin any suggestion on anyone! I just want to nix out all possibilities that I can correct myself. This is one of them, well minus the $500 bucks, but at least this is now done at/around the 250hrs and at the Agco suggested rather than my 100 hr previously done...

For Hydraulic Oil and filter(s) change, pls see this post: https://www.tractorbynet.com/forums/threads/1740m-hydraulic-filters-hst.419688/post-6821654

Oh yeah, one more thing.... When filling the Hyd Oil, carefully watch that site-glass. It's very difficult to see/read IMO, especially w new oil! Not to stir the pot, but I recall somebody posting (somewhere) that he uses Chevron THF Hyd. Oil and it's orange, WAY easier to see in the...

@567Chief I see nobody chimed in on this? So I'm getting ready to do this again for my 2019 Massey 1740M w Hydrostatic Drive; Hydraulic-Oil Change. From my saved notes; I have this info: And, I Put the Amazon links in the titles, but you can obtain from your preference of course! AGCO...

@ seville009 It might of been active this winter during snow plowing?, but where I live, we really didn't have much snow fall to actually use it beyond the 40 min mark. SO, I'm not sure it was something I did, or something that progressively has shown up. My first route of thinking after...

I see my last order I had this for $129, it's up to $179 now. Not surprised, everything has gone up but if it's not the Hyd oil everyone is using right now, like a total synthetic, I'll go that route. https://www.amazon.com/gp/product/B0B6QFLDG2/

@JWR I will order in and change Hyd oil again, what oil should I be using? I'm at a point where 400$ in oil and filters is an easy assurance and a sure checkoff from my list. ....I really didn't relate this problem to the hydrostatic drive, I was focusing more on a direct engine issue like bad...

@JWR My leftover 5gal pail says Permatran 821XL. It's got about half full left, and I know I used another full one as I looked up my purchase from Amazon. So I got about 7.5 gals changed?. I do remember when filling the site glass was not good to actually see the level, and I struggled with...

I have a MF backhoe also that I put on this Spring. Same as mower, awesome power to pull stumps early on, but that brute force is minimal towards the end of the job. I haven't timed that loss of power however. I also have a Snow Pusher that is rather large for this size tractor. We haven't had...

Would be a good call, but even when dis-engaging the mower (after work load of ~40 mins), it still acts like 10hp, really more like 5hp, but this is a heavy diesel vs a small and lighter gasser, so I'll be gracious and say 10! The mid mount (underbelly) mower is a 72in Massey model MF1705

I have to put this in the possibility category, and, will not rule it out!. The hyd filter and fluid got changed around the 100hr mark if I'm remembering. Did not know there was a fan on the Hydro system? hmmm.

@Tinhack All good q's, let me explain my term "Hot" first. I use this term because the tractor is well into the running/working mode temps which is about the ~40min mark (Way past any normal warm-up period). The temp gauge (shown in the video) shows only 2 to 3 bars, it's very dim but the...

My dealer is baffled by this problem, they had the tractor for almost 4 weeks. I guess a computer update was supposedly the cure. It was returned to me and was not the cure. I want to stress the time(s) in the video that the occurrences happen. My MF 1740M has plenty of power and torque until...

Just to follow up on my own post…. On the fuel filters, I used the WIX 33138 Fuel Filters. It’s plural, as you’ll need two and they seem identical (the one lower or next to the step (w the primer/pump), and the one on the engine itself which would be the 2nd inline of filters. I did the step...

The manual is pretty generic, maybe I missed it but what is the part# for the oil & fuel filters? I壇 like to Xref it to a major brand, Same with the fuel filter. I知 sure others will want the same. My dealer did the 50hr, but at $42 for just the oil filter I want to do it myself. Crazy also...

I (finally) got my promised LED Upgrade Video up and running. Sorry it took almost a year to do, I actually went through 20 different LED's and combinations there of. I finally was happy with this setup. My bank account is down quite a bit because of all the prior purchased LED's, so if anyone...

I've been shopping a new compact tractor since Fall '18. My current ride is a International 285 4WD (25hp, 3 cyl Mitsubushi). It only has 360 hrs, meticulously maintained and always been a garage queen. I own and maintain both wooded and groomed/grass around the house, a tad more than 2 acres of...

My better half would probably say... What, another Forum to join? Lol, yep. We reside in central NY, Finger Lakes to be more exact. I have both groomed and wooded property to attend to. Currently have a International 254. It's a 1986, purchased brand new back then, just out of school and my...
