I got a B7100HST 4wd. I changed the transmission filter and fluid. Now the control operates in reverse when pushing down on the forward end and forward when i push down on the rear end. The only thing I can think of is the dealer gave me the wrong filter as nothing else was changed, no hoses removed and it worked normally before this, what did I do? I dont want to put the old filter back on as it's very dirty. Any ideas? Nobody else seems to ever have this problem. Any ideas?

Isn't this the swashplate stop bolt machine?
Do not put the old filter back on... not worth risking getting dirt in there. I will assure you that's not the problem.
NIW, lugbolt, or white tiger should be able to help you before too long.

I have never heard of this situation ........... then again I never heard of tires spinning on rims on a BX!
SO anything is possible!
But the filter - assuming it is correct would not cause that - it is a one way flow device.
What fluid did you place in it?
Any way a linkage somehow came apart or anything under the peddles out of whack?
another crazy question ---- IF YOU hit reverse and it goes forward ....... does it move a "normal" forward speed or does it creep ?
Yes, this is the machine with that pesky stripped stop bolt. The hydraulics work fine, loader goes up and down, pto runs fine, just F&R work opposite.
It moves at normal speed. I used kubota UTD and the filter installed is the correct filter. The filter on the machine originally was not the correct one but apparently did the job. There are no linkages to that pedal, just a shaft and I never removed the hydro unit or disconnected any lines to it. This one has me totally baffled.
If the motor reaction plate turned 180 degrees the tractor would operate in reverse. It is so long ago I had one of those apart I can't remember if there is a hole opposite that you could put that pin into!

Yes, the only way this can happen is if the motor reaction block is turned 180 deg. I do not believe that there is a second hole for the locating pin.
I have seen a couple of B7100's come in that the hydro reacted opposite to the pedal and found they had wallowed out the locating dowel pin hole in the case allowing the block to turn approximately 180 degrees.
Here is a breakdown of the hydro. I do not know if the OP has an Early or Late B7100, so I just used the Late. The Motor block is labeled C and the dowel pin is #160 in the pdf picture.

Somebody else had the same problem. I asked if they ever resolved it.

Once upon a time my brother and I were playing on dad's tractor and seeing how steep of a hill (mound) it could climb. After a cough and sputter and started running poorly, we let it roll back to flat ground. Tried backing out and ended up going toward the mound again. Treadle was going backward. Tried killing the engine with the key and it wouldn't stop...
We managed to turn the engine around so it was running backward, and it started dieseling. We got it shut down with the e-stop button. Looked at each other for a bit, rather concerned, turned the key and everything was back to normal.
Moral of the story - I've once had a similar problem, but I assume your starter is still spinning in the correct direction, so it's not likely that your engine is running backwards. Plus, all your hydraulics, pto, etc work fine... You don't have the same problem we had.

You might be able to turn that plate to the correct position by putting the tractor in high gear and carefully pushing it to turn the assembly. I'm not sure this will work but it certainly is worth a try!
It would be nice if you updated that other thread, seeing that you got a lot of advice there...
Are you saying after you put the tractor back together, it worked fine? But then after you changed the transmission fluid and filter, it suddenly now works backwards?
Or that it has started working backwards after you put it back together with new transmission fluid and filter?
Seems like there would be a big difference between those two scenarios.

This is the residue of another thread where it was pointed out the WSM shows TWO versions of the HST in those models - Type I has a lock bolt for the fixed swash plate.
Type II has a drain plug nearby instead (hence the confusion) and has an internal pin 160 to hold the fixed swash plate from rotating. Tnkubotaguy's tractor has the Type I HST which has the lock bolt, but has no internal pin 160.
The WSM says after installing a new filter, run the engine at low rpm for a while before using the tractor. No reason given - but may be to clear air pockets in the HST?

Yes, I apologize for dual threads, I'm new at this.
Anyhow it ran fine before I removed the stop bolt thinking it was a drain plug. Anyhow, couldnt get the plug back in as didnt realize hole B was not lined up with hole A. Eventually was able to see hole B and got it aligned and inserted bolt, filled with new fluid and filter, started up tractor and treadle was reversed. So apparently removing the bolt did not flip the swash plate but did allow pin #160 to fall out and reaction plate inverted 180 degrees based on what others have written. Whats done is done, not a big deal, it's just a toy, now a backwards toy but still interesting and not like i'm gonna go jump off a bridge over it. I learned a lesson and I will more than likely come with a pedal design that turns the shaft the opposite direction when pushed. Any suggestions on that one?

Thought I remembered a thread about reversing the direction of an HST pedal, but I could not find it.
Maybe I'm getting senile.
Maybe someone else will remember it.

For those that hate the treadle pedal on Kubota
I love my Kubota L3430 tractor but hated the treadle pedal. I broke my right foot several years ago and even before it was hard to work the pedal for me. I am one that has to mod everything and this is what I came up with done it a couple of years ago and it works flawless. Just touch the pedal...

Twin Pedal Mod B1550
I am currently finishing up my twin pedal mod. I am leaving the treadle pedal as it is, but adding a 2nd reverse pedal beside the forward pedal. I'll post pics soon. Sent from my SAMSUNG-SM-G891A using Tapatalk

Yeah, that's sort of what I was thinking of as I'm not a big treadle fan anyway, I like my cub cadet setup. Since this is my first tractor and I have no experience on it, it's not even that bad the way it is. I was driving it all around the yard today and I like it. So, I'm still hopeful there is an easy fix for this, I'm certainly not about to tear apart the HST. Once I design a double pedal setup, I'll post it and let everyone see how nice it turned out. I thank everyone who responded and helped me through this unfortunate incident, and next time I'm gonna read the whole manual before removing bolts I am not 100% sure of their function.

Regardless of your preferences your tractor is not operating the way it is supposed to. Something is broken and needs to he fixed.

And now we get the "rest of the story" when all you did according to your original post was change the hydraulic fluid and filter.

Agreed.
.. That's why I asked the question. We're all just wasting time without the proper information.The only people that wasted their time were the people who had stupid comments, or unhelpful responses. I did not know at the time what happened as I thought all I did was change the filter and fluid, I learned from this site many things from many great knowledgeable people. I ended up getting a complete workshop manual, learned about the inner workings of a HST, learned how to make a taper on a bolt using my drill press, and got some great ideas on a mod for the treadle pedal. So maybe you wasted your time but thanks to the non-trolls on here, I learned a lot more about my machine than any dealer would tell me.
Have a great weekend to all.

I agree something is broken, but it does not need to be fixed. I live in TN where we dont fix everything thats broken, if it runs and does everything it needs to do, I aint taking nothing apart in 90 heat and humidity to make it perfect as if I went to the Dr. every time something didnt work on me, I'd be a hypochondriac and broke.
As one of you who helped said "The cheapest thing on my tractor is me!" I loved that and repeated many times already.

FWIW…Sincerely hope this tractor stays with you…in TN…for a long, long time, as the reversed function HST pedal is an accident waiting to happen. It’s like switching the function of brake and accelerator pedals in a vehicle or reversing the shift/throttle lever in a boat!
Hopefully… you, your family/friends, grandkids, dogs or anyone else unsuspecting doesn’t get injured due to this malfunctioned repair.
