What is latest opinion/position on BX series slow braking (is it an issue or not)?

[mshumack]

The damper used in the "speed pedal" linkage changed. It was part no. 32721-43350 on the BX25 then it changed to a K2651-42150 for the BX25D and BX25D-1. BTW if you go to order a damper for the BX25 you get the new part.
It looks like the damper action was increased on the newer models so that the pedal now returns more slowly to neutral position.

Now that finally starts making sense that the parts ARE different. Makes one wonder if any dealers have the old part in inventory . . would that be the key to correvt the 25d-1 problem just like that ??

mshumack, here's a question. On the bx2370-1 or bx2670-1 what part number does that damper have . . . The same older part number or the new one ?

So, is HST braking to a full stop or even "hill holding" actually a design requirement, or is it an aspect of HST function that people have come to assume is a requirement? Does Kubota, or any of the other tractor manufacturers, recommend getting off the tractor without setting the parking brake in their manuals? Just trying to clarify in my own mind if this is, in fact, a defect, or if it's more of a disappointment.

I have a 2008 BX2660 , I regularly go up an down a 15 % incline to my upper meadow (see pic taken many years ago my nephew riding it down) .

If I let off the HST pedal in middle of that hill , my tractor stops . I also often stop and jump off tractor (on level ground ) and do not use parking brake. When it does start to creep, then I know it is time to grease the HST pedal . And then I am good for a few more months.

Odd. I replied to you earlier and its not showing. Anyways, all of the BX series use the same part (the k2651-42150). And if you try to order a damper for the older BX25, you get the newer part (the old part no. has been superseded).
The damper (think shock absorber like in truck) slows the return of the pedal to neutral. There is also a spring that pulls the pedal to neutral. So the spring tension is fighting the damper action to get pedal to neutral. To increase the pedal to neutral (quicken the "return time") you increase the tension on the spring.

I wonder if the reason so many seem to have different stopping times is because of the way the Dealer (or manufacture) adjusts the spring tension before Customer picks up their tractor. I wouldn't be surprised if some Dealers make this adjust in the pre-delivery setup and others just leave it at whatever the factory set it to.

Or maybe some dealers still have the old spring tension adjustment on their pre-delivery checklists.

Okay, update - I got out last night and tested my tractor at full speed in high range. It does actually coast to a stop farther than I would have thought. Probably about 8 feet, but the HST does catch and stop it. I've never noticed this before, because frankly I don't and haven't ever done any chores at full speed. So I also mowed last night and under normal mowing speeds going down hill, it takes about 3-4 feet to stop with HST only. I had just changed my mower blades, so was mowing faster than normal also, so this is about as exaggerated as I could have made the conditions.

What I noticed most was as I approached my pond (straight at it in one spot), I actually feather my foot to the reverse position for ultimate control of where I stop with a tiny amount of back pressure. (I drive straight at it next to my ditch that feeds it, go in as far as I can, then back up a little and turn, then following the perimeter) I've probably been doing this the entire time and never noticed it since like I posted earlier, I just simply adapted to this machine.

I have some very steep hills and I did not use the brakes at all. If you are already going slowly, this doesn't freewheel or coast or pick up speed.

My end conclusion is still the same. For me, I don't consider this coasting to a stop to be a serious safety issue. It does not pick up speed and frankly, the brakes are there if needed. For others, I guess this could be a problem or a preference issue, but for me, I am still quite pleased.

Thanks tractorshopper. I don't remember if you have a bx25d-1 or a bx2370-1.

But nobody who is saying they have coasting concerns is about only 3 feet on a steep slope . . . Its considerably more they are experiencing and that includes after the dealers doing all they can in adusting.

So if you have a bx25d-1 . . Then count yourself lucky

I have a 2011 BX 2360 and it does not stop when I take my foot off of the HST pedal. I also have a Kubota G1900 lawn tractor with HST. The G1900 stops when taking my foot off of the HST pedal. I have gotten used to the BX not stopping but I don't like it and it is NOT SAFE! When using the FEL in tight places it is a pain in the butt because I have to always push the reverse direction on the HST pedal to stop it. The dang brake pedal is so long and high it is hard to use.

Stopping in 8' from about 8mph would be plenty quick for me.
