BX25D engine brakign vid

I must be really weird. I never use the brake except to park it or shift from hi to low (ie. too steep to climb a hill in high gear). I keep my foot on the go pedal all the time. When I want to stop, I rock my foot backwards. Sometimes I almost hit it into reverse. When I go backwards and want to stop, I rock my foot forward. Sometimes I almost hit it into forward (but it is rare that I actually change direction either forward or backward). I maintain control at all times with the angle of my foot. Stopping is not an issue because my foot is in the right position for what I need.

I guess if you had a 2 pedal system, that might not be as cool, but with the a rocker pedal, I just don't rely on the mechanics to know what I want.

That's a good habit to develop. Unfortunately, most of us don't do it that way. I think I'll work on developing that habit.

I have a BX 25D and it actually starting rolling down the hill fast when it was off. When I say fast it has always kind of slowly jerked down a slight incline. This was a fast jerky roll. This was a couple of weeks ago and hasn't done it since and actually forgot about it until I read this post. Not a steep hill and of course the parking break was not on. Is that normal?

If you had it in rabbit/high probably normal and the purpose for the locking emergency brake

I had no idea it was supposed to stop. I keep my foot on the brake when going down a steep hill.

An HST is supposed to stop going level, up, down hill by removing foot from the pedal. I to keep my foot on the brake going down hill on the BX25D but never have on any other Kubota HST.

Rocker or two pedal system has never been a difference to me. I press down forward to go forward and let off pedal to stop on all Kubota HSTs I've owned. I press backward on pedal or separate pedal to go back and release my foot to stop on all Kubota HSTs I've owned........until this BX25D which stops pretty quick (properly) most of the time in reverse after Kubota master mechanic adjusted it but some times, mostly, I release my foot in forward and it keeps going after Kubota master mechanic adjusted it twice. WRONG, WRONG, WRONG for a Kubota HST. Shouldn't have to brake or bump to forward or reverse to get it to stop, release the foot pedal should make it STOP!

Agreed, the 3 brands ( New Holland, Kubota and now Kioti) of Hydrostatic equipped tractors I have owned all stopped when you let your foot off of the directional pedals. Two were treadle pedals, and the Kioti is the 2 pedal system. Doesn't matter if you are level, reverse downhill, or forward downhill.. They all have stopped. As I mentioned earlier after a few seconds they will "drift" downhill when the oil pressure in the hydro drops after stopping. This is a slow movement downhill as gravity takes its toll. If you stop on level ground and do not touch a pedal, the tractor will stay put all day. I believe this to be correct operation. I have never run a hydro tractor into anything because the hydro failed to stop the tractor when the pedal was centered. In fact if you yank your foot off of the hydro pedal and your forward speed is fairly fast the stop can be very abrupt. Enough to pitch your body forward some out of the seat. You learn to release the pedal in a smooth controlled manner unless you want the stop to be abrupt. My two cents worth of observations.

I share the same two cents wit you.:thumbsup::drink:

I'm not saying your evaluation of the system is wrong. I think on a brainiac level I agree. I'm just saying for me, it hasn't ever mattered.

I have a BX2370-1 and I think there are two issues in play here:

1. When I let off of the pedal, it takes longer than I like for the pedal to return back to center/neutral position. Until the pedal returns to neutral, the tractor moves. Sometimes it is quicker and sometimes it is slower. This seems to vary depending on how warm the HST is. It also seems to vary based on how fast I was going before I took my foot off of the pedal. Not sure why or if I am dreaming.

2. Once the pedal has returned to neutral, the BX does stop... however if I am on a hill, it will slowly creep. Faster than I like, but not a real big deal.

My previous Scotts/JD/Home-Depot (built by JD) mower was HST and would creep slowly down hill, however it would return to neutral pretty fast. This is what I would expect.

My only other HST experience was on a New Holland. It was equivalent in size to a large L or small M Kubota. When you took your foot off of the pedal it stopped NOW... and did not move on an incline. This is how I would expect all HSTs to operate. Wish my BX did.

I am going to mull over my WSM and see if I can make any adjustments myself... knowing the behaviors going on here and what I would like them to be. Since it is mowing season, and it is something I can deal with for a while, I don't feel like taking it to the dealer... yet.

My bx2370-1 is the EXACT SAME WAY! After hearing JohnThomas describe it I tested over and over and it does the same as yours rjk. NOW....ive never had it roll into a truck or anything like JohnThomas but then again ive never had a loader yet. After thinking about this and all these stories im considering jumping to a B2301 when I buy my next one. Ive saved towards my bx25d upgrade but wonder if a B might be a better investment at this point. Scared to think how a tractor will react loaded on my hill or when im clearing those 3 acres of woods im buying or even worse, in a few years after warranty expires when one of my sons is using the tractor..... anyone heard of the same issue on any other series?

I know there is an adjustment in the service manual as Ive read it myself. Do you think stiffer springs or upgraded spring could help? Also, do you this stopping as center and holding when centered is an issue you could claim lemon laws on? What kinda input are you getting JohnThomas on this issues since you have had yours in the shop for it multiple time already?

You need to update your signature which says you have a BX2230 and no mention of a BX25D

I know there is an adjustment in the service manual as Ive read it myself. Do you think stiffer springs or upgraded spring could help? I don't know what would help or fix it, that's why I drove it over to the dealer for their mechanics that have worked on Kubotas for years to fix it. No, I think the dealer mechanic would have done something that simple
Also, do you this stopping as center and holding when centered is an issue you could claim lemon laws on? No interest in lemons but it's all or almost all BX25Ds, not just mine
What kinda input are you getting JohnThomas on this issues since you have had yours in the shop for it multiple time already?

Haven't had in shop but one time. I went down and tried it after their first adjustment and wasn't satisfied and showed them that it was still doing it and left the tractor. Returned a few days later and tried it again and better but still doing it so I said I'd take it since they had nothing else to offer and master mechanic said he adjusted it to the maximum and had no further adjustment or anything else he could do to make it any different. I will continue to ask Steve Barlow if Kubota has ever sent a fix but I'm sure he'll contact me if they do. Doubt Kubota will fix it or send fix for already sold units as long as no one or very few of us complain or refuse to buy them when they roll on like this. I'm signing papers for my my new zero ZD326rp this coming week and I will ask again if a repair solution has been sent.
