BX Neutral Return Position

[jruss]

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.

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.

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?

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.

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.
