Mahindra? Which series are Mahindra VS TYM?

Helitech · Aug 2, 2015

My neighbor has a 2 year old 6110, by TYM. It's at the dealership again for what will probably be it's second engine with only 145 hours on the tractor. Seems like each time it took forever to get warranty approval. Is this because Mahindra is having to work through TYM? Looking for a new tractor in the next year and like the "Real" Mahindras very much. (would love a 5530 or 6530) What series are built by Mahindra and which ones are TYM?

New series machines.

2500 series & M force = TYM built

3500, 4500, 5500, 60 series and M power are built by Mahindra.

I thought my 4510 had a TYM engine.

4510 has a Daedong. Thought the 6110 had a Mahindra-made turbo diesel.

Thanks

Looks like your series/manufacturer questions have been answered. But my goodness, 2 engines in 145 hours? We have sold a bunch of the 5010/6010/6110 tractors and have had zero engine issues. What is happening on this unit? Overheating? Dirt in the engine? Or just some mechanical failure?

It's a bit of a long story. His first few weeks of ownership a radiator tank ruptured, tractor ran warm and he shut it off. ( Not water spewing out hot, just warm) Replaced the radiator and everything was OK. The next spring he did a little clipping and drug the driveways then took it to the dealer for servicing. At some point at the dealership the tractor ran hot, started smoking badly and dropped water in a cylinder. They changed the story as to what happened no less than 3 times and stopped returning calls after the tractor was down for over over 5 months! They wanted to blame the owner and it took an attorney's letter to get things going again and the tractor repaired. A new engine was installed. After getting the tractor home it would occasionally lose water and sometimes would smoke on startup. Clipping with the air conditioner on would make it overheat. He took it to another more responsive dealer to have this checked and they found it's getting compression into the coolant system. They pulled the head and inspected and replaced the head gasket, still has the same problem. Now they are asking for help from Mahindra. The tractor has not been abused at all.

Thanks for the explanation. Sounds like the over heating problem remains for some reason and has damaged the second engine. I hope they get it figured out.

One thing I have noticed, when you get an air conditioned cab tractor you tend to work through the heat of the day, and can run the tractor for hours on end. On an open station tractor, when it is 110-115 (yes, we see those temps here) you would take a break and get back on the tractor in the evening. But with a cab tractor, you just turn the AC up a notch. Then as you mow, you are putting a decent load on the engine, which warms it up a bit. Then you have the AC running, and that heat is also trying to dissipate out in front of the radiator. You have a ton of heat coming in the glass, unless you have tinted your windows. Combine that with clippings filling up the spaces on the radiator and the AC condenser, and you have enough things working against you to cause an overheat situation if the condenser and radiator are not kept really clean. A hot condenser will not provide cool enough AC, and the compressor them works itself to death trying to cool the cab...which produces more heat and so on.

But none of what I have said above should be a surprise to any tractor company. These are not cars. Much of the USA is hot and dry during the summer. I think a manufacturer needs to create a radiator and a condenser that has a little larger spacing so as to not trap tiny bits of crud as it goes through these components. These really tight cores with fine spacing are the bomb in a laboratory setting where they can super efficiently transfer heat, but as soon as they clog, they are pretty much worthless to shed heat. Or they need to be able to screen the stuff out adequately before it gets to the radiator and condenser. Or like we see on some construction equipment, they need a reversible fan that occasionally reverses to self clean the air flow path. There are options to make AC work better in a farm setting I think.

I think I got off subject a little. But hopefully this will remind folks to do their best to keep things clean and let the air flow properly so they do not overheat. I'm not sure that is the problem with the 6110 described in the original post, it may be unrelated. But that is the common issue on overheating tractors. Almost always the radiator is clogged on the air side.

Something like my old 1256 International has a proper radiator. 25% of it can be clogged and it'll still cool the tractor. Just about all new tractors have a tiny radiator to me.

Yep, I had an old Ford 4600 orchard tractor and I mowed with it all the time. It had an old school radiator with really wide fin spacing, and it was larger than it "needed" to be. Crud just sailed right through, it never clogged. I am sure it was nowhere near as efficient as these new radiators. But no radiator is efficient if you can't keep it clean.

TYM made the old 10 series for Mahindra. According to Tractor data. The 6110 uses a Mahindra 2.4L Diesel engine. Don't see why they would have to work through TYM. It is their own engine that they produce. Not sure what is going on to create these problems, but they are not common to either the TYM or Mahindra tractors built by TYM.

Should be a Daedong aka Kioti engine. I don't think TYM is in the engine business. For their own machines they have used in the past. John Deere, Kubota, Perkins, Mitsubishi engines. New machines are using Yanmar, Duetz and Doosan engines.

As a point of information, the eMax 22 and 25 are TYM built with a Daedong engine. Weren't the earlier Max series engines built by Mitsubishi?

On the heat issue I've found the radiator screen about half or more obstructed after mowing pastures that got weedy, never an over heat situation but I need to clean it regularly and blow or wash out the radiator. My old Ford Ns on the other hand pretty much never clog much at all, about once a year I'd wash them out and was good to go again.

Max engines are still Mitsubishi, in fact the entire Max is made by Mitsubishi. I don't think you can buy a better small tractor.

You can't tell people often enough about cleaning the radiator. The typical overheating call is a clogged radiator, and people never believe us. "Is the radiator clean, can you see light through it 100%", to which the customer responds "yeah, radiator is clean, I cleaned it. I think I need a thermostat, etc". We then go pick up the tractor, and it will always have a 50% or more clogged radiator on the air side (outside). People brush off the debris that is hanging on the screen and the outside of the core, but never really get down to see if they can see light through it. I think our TBN folks are better, but just today we did another one of these. And unfortunately, sometimes people will run them hot enough and long enough to crack a head or blow a head gasket, and that is never covered under warranty.

The manure pile will clog the my Maxes radiator fast, even with an extra grate on the grill guard installed.

Helitech · Aug 22, 2015

A quick update on my buddies engine. They have determined that the cylinder head is cracked and will be replacing this week. Supposed to be ready Friday. As soon as it's picked up he hopes to promptly trade it on a Kubota. 2 years of ownership and it's been down 7 months out of 24 months. Can't blame him. Someone will be getting a super clean 6110.

OldGinTractors · Aug 22, 2015

Sold a lot of 6110's and zero engine problems. Sorry for your friends issues. BTW the daedong engines are pretty much a Kubota clone.

yanmars · Aug 23, 2015

Good information to know about the daedong engines.

Wascator · Oct 1, 2015

I'm new and reading for catch-up. In general you can't get most of this new stuff hot and you need to be more careful than with the old iron stuff. We bought a huge Kubota zero-turn at work, and it burned up two engines. There is a very effective chaff screen protecting the radiator, but it is so fine it seems to block too much air, and get a little chaff on it and it overheats. The kids we had running it just ran it to destruction.
I say it's poor design if a machine won't operate in 100 F weather loaded without overheating if it is in good condition. It needs considerable extra cooling capacity to make up for: partial blocking of the radiator external and internal; general aging issues, etc. If it is running at the edge when new and perfect, it won't be long before you have trouble. I agree with Dave: the old Deere tractors we run at home seem to be unstoppable and I don't recall one ever overheating.
