BX Neutral Return Position

[manonthehill]

My Kubota BX1850 keeps going after I lift off the pedal. The manual said I have to take it to the dealer. I知 not interested in that. Does anyone know the procedure for adjusting the neutral return position?

Thanks!

Do you have a "rocker" type pedal?...If so, are you keeping it greased?

Mine does this to a slight degree, just have to tap the pedal to get it to stop

 

[ampsucker]

mine does it to.

did take it to the dealer.

still does it.

worst when cold outside and i am holding down in full forward for awhile - like when driving across the yard at low rpm.

not sure it can be fixed without replacing parts. i'm suspecting the oil in the damper gets thick and just won't let the spring return it.

Mine creeps forward and I have to tap the rear of the rocker....has ever since new.

 

[radioman]

same here , but the problem is lessen to a degree when you tighten on the rocker adjustment jam nut underneath ther carriage. keeping it well greased helps to a degree, but still does it.

Yes, I greased the pivot. Still happens. It doesn't seem safe to let it roll after your foot is off the pedal. I know there must be an adjustment somewhere.

Same with my BX23...Seems not as responsive when it's cold...I tap the pedal to correct and don't think much of it anymore.

I've complained to my dealer about this on my BX24. He sent a tech out that squirted everything with fluid film. From my experience with FF, that only gums up the works. The tech looked for an adjustment that wasn't there on mine so he suggested waiting until the fluid film works in (it didn't). It creeps both forward and reverse. Last snowfall my wife was standing in the garage door opening as I was backing towards her and at the last second, she decided to get out of my way and moved between the rear blade and garage wall behind me. She almost got pinned between the rear blade and the garage - extremely dangerous move but moreso because the tractor didn't stop when I lifted. It was close to broken leg (or worse) but I had presence of mind to punch the forward pedal. If I went for the brake pedal instead, since it sits higher up of the deck, there wouldn't have been time. It was that close.

Could have been bad. Still waiting on a fix. Also dangerous when snowblowing near the road since the BX24 creeps out in the road. There's enough to keep track of in your mind when snowblowing and this only adds to it. Check traffic as I approach the road, watch for vehicles, especially plow trucks, turn on flashers, watch the snow bank for foreign objects, right hand ready to pull lifting lever to lift blower, as well as crank the chute, left hand ready to stop PTO, now add get ready to lift my right foot and brake to keep from rolling into the path of traffic.

Yeah, when there's nothing around me, I just tap the pedal, doesn't matter. But when it matters, it matters bigtime. Needs fixed.

There is an adjustment where you can lossen a lock nut and tighten up a spring. That helped a little bit on mine but not enough so I took it to the dealer and they replaced the strut that controls it. It kind of looks like one of the those shocks that hold up the deck lid or hood on some cars. That helped alot on mine. It still does it a little bit but when it does stick, its very slow. Before it would stick at a forward speed that was dangerous. When the dealer took the strut off, they said they could feel a notchy place in it.

 

[PeterK]

Thanks. I'll have the dealer check out that part. They're good and have a tech that lives nearby so he comes over when ever I need something.

My bx2200 did the same thing, I tried greasing the rocker pedal, changed the dampener and took the linkage allmost fully apart at the HST. Tried lubing the linkage at HST and then used brake cleaner to clean the linkage as lubing it seemed to make it worse. Finally found that running it at full throttle in high range seemed to do the most good. Have not had the problem since.

 

[redharley]

my bx has also done this since new dealer told me to lube it and so on,it goes back to sticking in a short while again.like said its not a big deal if your in a 5 acre feild but can become a very big deal in the wrong place or time.I'am surprised someone has not had a law suit over this being it's been a problem for so long.If anyone ever needs there's plenty of info in these threads to back up their suit for sure on this subject.

My BX2200 almost never does it. I wonder what the difference is. I have adjusted mine once "by the book" but I have never lubed it in any way.

The most favored place the pump's swash plate "wants to be in" is in what ever position allows the pistons to NOT pump oil. Any other position creates a reaction force against the swash plate.

On a level surface, the spring return on the peddle should combine with the pump piston's reaction forces to center the swash plate. On any other surface, the spring is actually fighting to center the pedal, while the tractor is trying to press it off center.

If you do a test, you should at least find that the tractor moves very slowly and cannot push very hard. If not, your linkage MUST be binding.

The spring system should hold the tractor still on most flattish ground. But it is not surprising if on a modest grade, it rolls.

When it counts...only the brake can be expected to stop the tractor. This is a truth of the machine.

I always try to remember to use the parking brake too. It's easy to forget, since mine never rolls. But I should not expect it to stay still. On a grade, if you park a hydro-transmission tractor on a grade, turn the engine off, and wait, you will see 6 - 8 small movements of the tractor while hearing 6-8 grunts from the tranny (one per piston.) Then the next thing you know, you'll be free-wheeling down the hill with nothing but bearing friction and a head wind to slow you down! Try it...you'll see. It may take a while, but it'll do it.

Lubing does improve mine but it still does it. It is just habit now to tap the opposite direction to make it stop - I don't even think about it, the foot just does it!

A park position like an auto tranny has would resolve this issue.

 

[sw03]

talk about an OLDDDDD issue. That issue has been around since the org TLB on the BX..

 

[TigerfaninAR]

Is this strictly on the 50 series or is it on the 60s as well?

 

[Cooldmax]

My 2660 does it. I've increased the tension on the peddle return spring and it helps but did not solve the problem. I am going to add more tension but haven't had the time yet.

 

[Mustangous]

I just took my tractor back to the dealer a few weeks ago for this and they put a new damper/shock in and lubed. It did nothing, still haves that problem.

This issue goes back to 2002 from the BX22...I have watching thi site from 2003 and do a search...Nothing new.
