BX-22 / BX-23 HST Creep

[Rimmer]

There were several posts on this subject back in June, then the discussion seemed to dry up. Has anyone found a fix yet? At 23 hours my BX23 started doing the same thing. (Slow, uncommanded forward motion when in either high or low range.) I called the dealer this morning and asked if there was an adjustment. He said, "Yes there is. I don't have anyone available today. I'll have a man out there tomorrow to take care of it."

Based on previous posts, plus a bit of poking around under the tractor, I think I know what he is going to do. Just wondering what others have found.

At any rate, I'm pretty pleased with my dealer's response so far! This will be the second time someone has come right out to make a minor tweak. (First time was to add about a half quart of Super UDT.) I was just going to ask if he could tell me what to do, but didn't even get the chance before he offered to send someone out.

BX2200 HST Pedal Sticking (It's Not the Pivot)

My Bx2200 did something similar and it was the linkage...

Two things I noticed was the tendency to move on its own, rather than stay still when my foot was off the hst pedal, and a slowness in stopping when I took my foot off the hst pedal.

When I first got the bx, I was surprised how quick it stopped compared to my B2910. The the bx gradually changed from an almost neck-jerker to a drifter when I took my foot off the hst pedal.

Following advice from others here at TBN, I sprayed everything with some lube...might have been LPS or something else I had on hand...and the bx was soon back in the quick stop/no creep mode and remains that way now after several months...

Your problem may be entirely different, but a little lube sure fixed mine... /forums/images/graemlins/smile.gif

Thanks for the reply and info. I should have mentioned that I lubed the pedal pivot, and checked the linkage. The linkage appears to be free, and it snaps back to the center position quickly (not just the pedal -- I can see that the centering mechanism is dropping back to its lowest position -- difficult to describe, though). I did spray it with silicone lubricant just in case, but no effect.

Putting very slight back pressure on the pedal haults the forward motion, but as soon as I let go it starts moving forward again. From this I am assuming that it is not the linkage binding, but I could easily be wrong.

There appears to be an adjustment arm underneath, but it's difficult to see exactly what it is connected to without pulling the right rear wheel and tire. Guess we'll see just what the dealer does tomorrow.

Just in case someone reads this thread in the archives sometime...

I am pretty sure when I touched my reverse direction and then let it go, the tractor held position and did not try to move forward anymore. Guess that is the test to see if it is linkage hanging up or something else...

I took my BX2200 to the dealer for the sticking Hydro pedal and they applied a fix on a Kubota service bullitin. A week after I got the tractor back it started sticking again and it still sticks today. I talked to the dealer about it and they told me that they have had other BXs with the same problem. I don't think that Kubota has a fix for it. (I did try spraying everything with lube but it didn't work in my case)

Creep in the neutral position is a different problem and there is an adjustment for that.

Rimmer,

There is an adjustment to solve your problem. It does not have anything to do with the pedal itself. My bx-22 had a similar issue except it would creep in reverse. It was pronounced with the RPM's up. The adjustment is under the right fender just above and to the right of the rear tire. The procedure is quite simple and it is detailed in the workshop maunal. I would recommend you pick one of these up. You can buy the manual from your dealer for around $60 or so. It has great info about small tweaks and adjustments in addition to tests for the hydraulic system, hose routing, electrical etc. Money well spent in my opinion.

Tom --

Thanks for the advice, I think I will pick up a copy of the shop manual. I have always done this for my on-road vehicles, even though they run about $130. (Probably more now, last one I bought was for my 1994 GMC.)

Many years ago I had a problem with a Grand Am that would only manifest itself when the temperature dropped to around 5 degrees, and would disappear within a few minutes of starting. No way the dealer was going to find that one! Using the manual and my DMM I was able to probe the ECM and finally went to the dealer's service manager with manual in hand. He took me to his ECM expert, I explained my findings, he agreed, and the next thing I knew they had the transmission opened up to replace the "Second Gear State Switch" (under warranty).

The shop manuals can really help!

Well THAT was easy! The mechanic came out this afternoon and adjusted the part that Tom described. Looked to me like it was going to be difficult to get to under the fender and in front of the tire. The mechanic walked up, lifted the seat (I NEVER remember that the seat lifts up!), loosened the locking bolt, started the tractor and put it in gear (don't try this at home), and moved the lever until the creep stopped.

I asked him to order a shop manual for me when he got back to the dealship.

Oh, yeah, before I forget: No snow -- 61 degrees here today. BWAAAAHAAAAAAAHAAAAHAAA!!! (Almost 15 degrees above normal.)

Sure would be nice to know where you are from.... if you are in Florida, I would say that is awfully cold for this time of the year and if you hail from Maine, that is mighty fine weather you are having. I often wonder why people never fill out the profile with some basic information... you don't have to be specific with your address, but a city and state will suffice.. or at least a region, such as "Near Albany NY".....
