John Deere 4410 e-Hydro issue (maybe)

[Daves_Farm]

Hello, long time member, just haven't been around much. I recently purchased a 2002 John Deere 4410 e-Hydro trans. It has the 430 loader on the front and a 48 backhoe on the rear. The problem I'm having is that I get no forward or reverse drive until I have the RPMs up around 1500 or higher. Below that, there is nothing. Loader and backhoe both operate fine at the lower RPMs. Another thing I have noticed is that when I'm driving at around 1500 RPMs, steering will cause the tractor to slow down. A full fluid/filter change was recently done on the tractor, with nothing out of the ordinary noticed in the fluids. When driving, it seems to have plenty of pulling power, just not anything at lower RPMs.

Wanted to get some opinions before I started really digging into it. I've seen some threads that mention charge pressure, but wasnt' sure if that was the right direction to head. Any help or suggestions would be greatly appreciated.

Thanks,
Dave

:welcome:
To the TBN forum Dave. Glad you finally are letting us know you are here.

I can't help with that problem but someone on here will be able to shortly.

Does the return line at the hyd pump collapse, or partially collapse? It may be as easy as cleaning the pre-filter screen.

Did you clean the sump screen when changing fluid/filter ? as already mentioned..

Also, are all the e-buttons in the correct position ??

 

[Daves_Farm]

Sump screen was cleaned. I haven't looked to see fi the return line is collapsing, but with the screen cleaned out, I'm guessing that's not going to be the case. I'll check this afternoon after I replace one of the hydraulic lines on the backhoe, decided to take a hydraulic fluid shower the other day.

How many hours? Is the hydraulic oil foaming? The power steering, 4x4 cylinder and the hydro trans are all fed from the front pump. The rear pump feeds thenloader, 3pt and backhoe.

The oil goes thru the power steering valve before it feeds the hydr trans.

Might have a bad front pump. There is a solenoid valve on the right side under the operator station that has a test port. Pressure should be at 175 psi.

If you are getting foaming oil you have an air leak on the suction line.

 

[Daves_Farm]

Tractor has right at 500 hours. There is no foaming of the hydraulic fluid that I have seen either before or after fluid change. I'll have ot see if I can get a test set put together to check the pressure at that location. Forgot to add that when it is moving, it does have a whine to it, not sure if that will help with internet diagnosis.

Thanks for your help.

What gear is it in? If you have it in C it might do that. Move bit to Aand see what it does. Try it in N and see if it still whines. Is parking brake off? Sounds like it is over loaded somehow.

 

[Daves_Farm]

Does it in all three ranges, A,B, and C. Parking brake is off. No noise at all in N. At lower RPMs, there is no whine at all, even though the tractor isn't moving.

Lift the rear end and check if the rear tires rotate. You should be able to rock them. I assume you are in 2wd. If not try again to eliminate the front drive.

These tractors are know for the brakes locking up. The seal on the brake shaft is far in the housing and it corrodes. Several threads here on that.

I had a similar issue and discovered that it was resolved as easily as flipping the Load Match rocker switch back on.

I had this on a tractor last week also and just had to reset the load match settings thru the dash as mine did not have a switch I have the printed instructions -but my scanner has issues [again ] I can type in an email if you need them its also in the operators manual -that's where the dealer copied them from

Load match rocker switch left of the steering wheel is my guess too.

Are there any error flashes going on the amber light?

Come back and let us know what you find out please.

Checked the tractor this evening and the rocker switch was rocked forward, which I think means loadmatch was on. Had to get a hose put back on the backhoe so I didn稚 get to test it out. I値l try it tomorrow and see what it is doing in the other position. Also, I値l check if I知 in 2wd or 4wd.

Thanks for all the suggestions and ideas. I do appreciate it.

Also, no error codes are being sent to the console.

That should do it then I hope. Your explanation of symptoms reminds me of what my 4310 would do if the load match was on. I leave it off 99.8% of the time.

Checked the tractor this evening and the rocker switch was rocked forward, which I think means loadmatch was on.

I took a look at the 4410 O-M: The rocker switch is vertically oriented and the function is ON when the top portion is pressed IN, per the manual. (Same as my 3320).

I wish there was a dashboard light for this, especially since the switch lettering is long gone. The local Deere service manager (who kindly charged me $0 when I brought the machine in expecting a transmission overhaul and instead got a lesson about load match which did not involve the word "idiot") was surprised that there wasn't a light too.

A few other thoughts on this -- I usually run at 1500 rpm as a general rule, the tractor is pretty sluggish lower than that, always with load match on. Below 1500 rpm, if the LM is off and in 2WD, the tractor is basically immobilized. That said, if your LM is on and you're running at 1500 and the tractor is immobile, then I'd think that either the LM isn't working, or ... something else is wrong.

Another way to test the LM is to press the rocker on the downside (LM off), run at about 2,000 rpm and drive the loader into an immovable object to stall the engine. Then, press the rocker on the upside (LM on), run the machine at about 2,000 rpm and the drive loader into an immovable object. If the machine doesn't stall but just throttles down, then the LM is working.
