Update on all 7520s

[MtnViewRanch]

I have been wondering, out of the almost 800 Mahindra 7520's that are out there, how many have problems? There are a few that show up here on TBN, but how many would you speculate that actually have problems of concern?

My uncle had a large manufacturing company, and he was happy as long as less than 3% of the product had problems. From what we see here on TBN, it is less than 1% of the 7520's. I know that most 7520 owners don't even know about TBN, so what would you guys think, 2-3%? Do the dealers have a way of checking this? Just how good are these things?

Of course all this is of little concern to me, since mine has been great and trouble free, so far. (knock on wood)

from my experience we've had very little trouble from the 20 series tractors. there is one unit that has been in our shop several times but 9 out of the 10 times it has been something the user tore up on it, this unit is used commercially along with 2 other 7520's to mow up and down the side of an interstate using 15 ft. Woods Batwings.

Dave, since you are posting now, does this mean that we aren't getting loader lift times today? Come on, it should take less than 15 seconds to do the actual testing.

I'll respond since I didn't see a response to this.

It sounds like you are having a problem with the KSB sensor/timer. It's a very quick fix, takes 1 minute to replace. The KSB timer adjusts the amount of fuel the engine gets when the engine is below a certain temperature, therefore the tractor will smoke and sputter because it is getting too much fuel while the engine is still cold. You should received a jumper plug and a new KSB Timer relay, this will more than likely fix your problem.

These are the part #'s you need..

KSB Timer #007700570D91
KSB Jumper #007700572B91

These should be covered under warranty regardless of the length of time you've had the tractor. This is a very well known issue with Mahindra.

RedRiver,
After reading your reply, I called my dealer and verified the issue with him. He said yes, that is the same issue he suspected, the parts are in, they are the 2 parts you specified and he is coming by Monday to install them. He said it should take only 2/3 minutes to install. Hope this fixes the problem.

It's a hard pill to swallow when you have an almost new and almost $30,000.00 tractor that smokes like a tar kettle!

Thanks for your reply.

Dave,

Give me the specific details and the location of the hose that needs the paint scraped off. No, I have not tried to do that. Don't know where to start until I know more specifically what hose/connection you are referring to.

Thanks,
Billy

Takes me longer than that to get out of this warm office. The tractors are outside on the lot, and it is cold and rainy. Even so...for the sake of the cause...I'll try to get it done.

 

[RedRiver]

are you guys just wanting the time for lowering/raising? it's clear, sunny and warm here today...

Pat, apparently Mahindra's supplier had a VERY large batch of bad KSB sensors go out. We continuously dealt with this issue for several months in a row thats why I'm quite surprised your dealer didn't immediately know what part/issue your tractor was having.

It's a VERY quick fix, as simple as plugging/unplugging a lamp into the wall socket.

The KSB timers have been a nuisance. We thought we had all of ours switched out, then ran across a couple that were acting up. We are now trying to figure out if these units accidentally still had the old timers, or if the new timers weren't right. Fortunately it is a quick and easy fix.

On the hose, have your dealer point it out to you, but it is a short rubber hose that couples the return (suction) line that is going back to the pump.

I just went out and tested a 7520 4WD on our lot. I let it run for about 10 min. ran the rpm's at 2100 and it lifted to full height in 6 seconds flat.

Dougster, weren't you the guy that showed a picture of your tractor next to your wife's Vette? Poor, poor, man! If the wrong guy, my apologies! You can even test drive a 7520 here if you want, even if you don't own a new Corvette.

That Vette is as old as the hills with more miles on her than Joan Rivers... and was paid for long ago when I was still working and earning mucho "OT"! Haven't had it that good since I can't remember! Can't even afford to put gas in her now. But once a month I buy a lottery ticket just so my dream of someday owning a 7520 4WD w/ML275 and 511 can be kept alive!

On the hydraulic pump issue, speaking directly to the Mahindra service rep and giving him specific questions is the best way to go.

Dave - These guys here seem quite intelligent and I believe I've read more than a few times that they have attempted to get some attention from Mahindra on this issue. Having called and written to Mahindra on other issues myself, I know how hard that can be. If you can do those ML275 lift speed tests you talked about with your new 7520 and 6520 machines, you would be doing a great service to those guys and would once and for all resolve the issue on whether or not those two hydraulic pumps/pump capacities (i.e., 6520 vs. 7520) are the same or, in fact, different. That alone would be a giant step toward solving the mystery. You and the other dealers here on TBN do all of us Mahindra owners a tremendous service. We cannot thank you enough. Where the factory falls down, you guys fill the gap. I'm not sure Mahindra would be such an attractive brand if you gentlemen were not around.

Can you save that one for me until I manage to win the lottery?
