BX1800 Creeping Problem

[nmk61802]

I received delivery of a new to me BX1800 a few weeks ago. I have noticed that it has an issue with creeping forward when left in gear unless light pressure is put on the rear of the hst pedal. I have replaced the neutral return spring and the return damper, but the problem still seams to be there. I have also tried adjusting the return spring pressure, and the length of the pedal rod via the hemi joint, nothing seems to make any difference.

What am I missing? Does the Owners/Operators manual list the adjustment procedures (I don't currently have one)?

The pedal does have the only grease fitting on a BX and you have greased that, no doubt?

That was the first thing I did prior to replacing the other parts

My bx 24 does the same thing. For me it's just habit to set the brake before getting off, while the tractor is running.

My BX2350 does the same thing too, I blame it on all the old grease around the pedal pivot. Someday I'm gonna remove all the old grease and lube it with something lighter than chassis lube and see if that fixes it. Maybe somebody has already tried that and will let us know if that fixed it.

My BX2230 does that from time to time. It really doesn't bother me since I have to put it in neutral before getting off or the engine dies.

I have same issue too- usually when I see it creeping, I just slap the hst in opposite direction of it creeping to put it in its neutral sweet spot.

I do find that when it sticks, its time for a greasing. Light duty grease seems to work better then heavy duty for BH or FEL grease. FYI , I took my HST pedal shaft apart once and cleaned it and it seems to be very smooth in operating, when it has lots of old grease in it, it seems to become sticky over time.

i use that white grease and its better

Just a thought-maybe we should be using a synthetic grease for HST pedals.Anybody using it for this application?

I tried the green grease thats is synthenic and it seems to gum up more for HST pedal.

Does your BX creep when cold and hot also ?

I think I fixed my creeping issue today. Got my service manual out and reset the neutral location, and added some preload to the return spring. These two changes seemed to make quite a difference.The pedal still sticks somewhat though. I had hoped to disassemble and clean the pivot but could not find a way to remove the pivot frome the tractor.

My BX24 does the same thing, but as mentioned above, it seems to do so less as it gets hot. At the advice of the dealer, I hit the whole mechanism with WD40 to wash it out a bit and that helped, but it still does it, until the hydro fluid gets nice and warm then it quits. So also like others, I just tap the back button and set the brake.

My 2230 has this nasty habit and it's cost me. I expect the tractor to STOP when I release the pedal. Instead, it slows down but keeps going. Buggered up the front cowling when it ran into a trailer while mowing. The grease fitting seems to be next to impossible to get to. This spring everything get's torn apart on that linkage, cleaned and reset. Hope it works.
