New 4052m Hydraulic temp light.

[Seven Gables]

Good idea to rent the Kubota , got your grass mowed and an excellent comparable tractor . The kubota temps sound typical of a properly operating transmission. You made a good observation about the reduced fuel consumption with the kubota. The Deere with it’s transmission inefficiencies is wasting a fair amount of fuel just creating heat instead of useful power. Have you ever driven a tractor with a power shuttle or as Deere calls it power reverser transmission? That would be my preferred style transmission, by design more efficient than hydrostatic and very simple to operate. Thanks for the update and good luck, surely a frustrating situation for ya.

So the reason we picked this tractor is because my inlaws have one too. It is the power reverser and we like it a lot which is why we went with this tractor. We thought the hydro would be better for mowing as this tractor is basically going to be for mowing and this trans was the one that dealer recommended. So is it a defect causing the high diesel consumption or the hydro trans causing it?
It is frustrating because we need it now which is why we bought it and we had to wait 3 months for it and now its been another almost 2 months and still no tractor and no real answers. I hear of a lot of issues with Kubota too so we just do not know what to do at this point. At least the dealer is trying to fix it. Its almost to the point that it seems they have gotten these tractors so high tech that they can't even repair them! We have even thought about just trying to find something older and used but we didnt want to deal with issues so that was why we went new.

Deere makes two transmissions options for your 4052m ; a 12 speed geared transmission that features a clutchless forward/reverse lever you operate with your left hand, this is what Deere calls their Power Reverser transmission. The other option is a hydrostatic Transmission which uses hydraulic oil between a variable displacement pump and fixed displacement motor instead of gears to transmit power. Deere calls this transmission the ehydro transmission , forward/reverse is controlled by pedal under your right foot. This I’m quite certain is the transmission you have and is causing your overheating hydraulic fluid issue . In layman’s terms it’s slipping (excessive internal leakage/bypassing hyd fluid) which is causing lots of heat and reduced fuel efficiency. You’re engine (Yanmar) is fine. It sucks to be in your situation but at this point just have to see what Deere is willing to do. If Deere was willing to trade your tractor for the same tractor equipped with there 12 speed power reverser transmission for little or no cost that’s what I would take . Good luck

So we heard from them and they changed 2 valves out.. the rockshaft valve and relief valve. Said they were bringing it back in the next couple of days. I really hope this fixes it!

I wonder....is it getting hot because it is dead heading?

What is dead heading? They had removed the loader off this tractor for us. They are saying that the removal of that loader is what is causing the issues and it has to do with programming. Which is really not making sense to me because they have these loaders with the quick release that operators can remove at will and reconnect.

Well, what I was wondering is if the valve doesn't work right so the pump is always working hard because valve/linkage issues. That would cause heat.

definitely seems as something was malfunctioning to me..

You have a dealer problem. Blaming this on Deere tractors is not right. Your dealer is not willing to get a mechanic that can find and fix the problem. But maybe this time will be a charm and the relief valves have corrected it.

Well I don't know what else they really could do, They ordered the tractor, it was delivered to me with 1.6 hours on it and the issue would only show up at 2 hours of straight runtime. When I had the issue, they came and picked up the tractor and did what test Deere told them to do and everything they told me, Deere confirmed. When I told them I was not happy with the answers or lack of answers, they then came and got the tractor again and went to working on the issue again..

Unless I am missing something...

I hope the valves fix the issue! If they were causing cavitation or ?, that would heat up. Give it a try...good luck!

 

[Seven Gables]

I hope the new valves fix it as well. I believe Deere’s thinking on replacing the valves is they could be faulty with abnormal internal leakage causing excess heat load. Definitely is a possibility but could also be just a easy component change Hail Mary their throwing at it. Did the dealer seem confident he fixed the problem? Or more of a try this and see what happens? I also at this point don’t see how removing the loader would have anything to do with the issue. Hook it to your side winder and see what happens

I agree about the loader..after all, they have quick connect loaders that they take off all the time and then put them back on so I dont see how the loader could be the issue. He said they ran it for 3 hours with no issue and before they did have the exact same issue at 2 hours just as we did. SO I guess we get it home and try it out and see. It poured again so the grass will need mowing again pretty quick!

 

[Seven Gables]

Good luck with it, be nice if possible to see a picture of the tractor and mower in action

 

[Isadream]

Well it does appear that replace those 2 parts helped as we have ran it twice now with no issues. We just ran it 6 hours straight and when I shot all the components with the heat gun, they were 160ish-190. Not a single one was over 200. I would say it was definitely overheating! Hopefully this will be a good tractor for us. Here is a pic of the tractor with the bushhog. We did paint the bushhog to match the tractor!

Great news those new temps sound about right

I see from your photo that there is no loader mounting frames on it. WHen did the loader get removed? Was it before you originally took delivery? If so, my guess would be that the dealer didn't connect hydraulic lines properly or maybe didn't remove an internal pipe plug when loader valve and joystick were removed. This would have caused the hydraulic pump to stay in relief which would have caused the overheating and also extra fuel consumption. Does fuel consumption seem better now? Probably have better power also.

Hi! Sorry I just noticed this. Yes the loader was removed before we got the tractor and yes the fuel consumption is half of what it was. We did not notice a difference in power but then again we were not using it hard. We just mowed for 8 hours with it and used a little over half a tank. Before we were using 3/4 of a tank in 3-4 hours. Also, we shot the same components again with a temp gun and nothing was over 200, I think the hottest we found was about 190.
