Issues already? New mx5400 steering issue.

[Henro]

Much ado about nothing that isn't normal for hydrostatic steering.

I think this actually is something that IS normal for HST steering.

AND something that is of interest to those of us who never thought about the issue...it never hurts to learn about something never thought about previously.

I checked this with my BX2200 this morning. Without a loader I never have reason to push the steering to its limits, since if I hit a travel stop when turning, I stop turning.

Anyway, when continuing to try to turn the steering wheel after hitting the travel stop on the BX2200, I noticed that the steering wheel will continue to turn slowly, in a bit of a jerky fashion, like a pressure relief valve was tripping and allowing fluid to return to tank.

Looking into it further, I see the steering controller on my BX has a built in pressure relief valve. So this much makes sense.

I THINK I got the wrong impression when reading the OP's initial post. My impression was that the steering wheel continued to turn with about the same (or less) effort than what was needed to turn the wheels before the wheels stopped turning.

In my case, the amount of effort changes. Once the travel stop is hit, making the steering wheel to continue to turn takes more effort. A noticeable amount more.

I believe the conclusion that the OP's situation is normal is probably correct. At least if the steering wheel is not free wheeling when he experiences the issue.

Correct. I was misremembering the behavior when I posted. Either that or the issue is somehow heat related. I corrected this statement later in the thread.

In my defense, this all started when I couldn’t back out of a spot in the woods bc my wheels wouldn’t turn. Hence the concern.

No defense needed. If we all knew everything about everything, then we would not need to ask questions, would we?

But most of us do need to ask questions...

Not trying to sell John Deere but here is an interesting video. Check out the video at 1 minute 7 seconds. I have a Kubota mx4700 myself with the same steering issue you describe. Seems they under designed the steering mechanism. I have noticed that in my case it is slightly worse on hills and have therefore slightly overfilled my hydraulic fluid.. Seems to help a bit. Hope this helps!!

Interesting Keep in mid that JD plastic hoods crack too. I have a power reverser and 2 speed PTO on my Kubota's but then they are M series large frame. I agree, for loader work, it's hard to beat a power reverser or as Kubota calls it, Hydraulic shuttle and no clutch adjustments on either of mine because neither have a dry clutch. Everything from the flywheel / damper plate back is hydraulic. Never owned a dry clutch tractor. Just something down the road (and hours) that will need replaced

The video at 1.07 does indeed show what is relevant to this thread

But I gotta say I hate when MFG's (ALL OF THEM) make video comparisons that are totally un-realistic.

The 5-series deere is comparable to an M-kubota. The MX should be compared with 4000 series. But then again....you cannot use HP as a sole method of comparison as deere is clearly trying. (then they compare to a gear kuobta) and say how much better the power reverser on the deere is for loader work. So stupid......ONE of those two tractors IS offfered with a HST

Maybe kubota should do a video comparing deeres 2038 to the GL4060....or even compare the X590 deere to the L2501 kubota. Would make as much sense as their comparison

That is NOT how hydraulics work. There is NO demand to "hold" the load up in the loader. The loader is NOT taking fluid away from the steering ability when you are NOT moving the loader.

Yes I understand, I’ll have to verify if that issue occurs just seconds after lifting a load while it’s in standstill, or while lifting the load and turning, in reverse to back out of picking up the load.
Thank you
