BX25D engine brakign vid

[millsan1]

Well, as I posted, I am a complete newbie. Will take some more vids in different setups and do some measurements.

I live on pretty steep property, so can get some idea there as well.

Thanks for the information guys.

Many people are/were happy with the abrupt stop in reverse on the BXxx50 series and that's fine but they were/are wrong. Many people will be happy/OK with the rolling stop on the BX25Ds which is also wrong. I wasn't happy with the BX2350 abrupt stop and traded it back to Kubota dealer and rec'd some additional compensation from Kubota. I traded it to a BX2660 and it stopped right in reverse.
I've taken my BX25D back to the dealer and the master mechanic worked on it twice and said no more adjustment available. It's still "not right" but I'll live with it. I'll never say it's right as long as it keeps rolling after the foot pedal is released. What ever the reason and lots of reasons and fixes were given by owners/observers for the BXxx50 series but none of them ever worked to stop the abrupt stop in reverse. Kubota has done something in the BX25D dynamic braking system that has made it wrong. I believe the next series will be fixed on the fix will be done to new BX25Ds with no announcement. If I were buying again I'd refuse the machine until the dynamic braking was fixed/changed. I'm certain all of the BX25Ds on Barlows lot does the same or did a month ago when I took mine in.
What ever the reason or fix, it should immediately stop when the pedal is released abruptly and easing back on the pedal should let it come to a stop based on the amount of let off on the pedal.
My RTV1140 will throw me thru the windshield if I let off abruptly on the foot pedal but will gradually stop with easing off the pedal. That's operating right. This also isn't my first BX25 or even my first Kubota HST in the BX, B or/and L size.

I'm having a hard time following you. You ARE or ARE NOT OK with the abrupt stop when taking your foot off of the pedal. It seems like you contradicted / flip-flopped several times here.

It doesn't stop abrupt when foot is taken off the pedal it keeps coasting That is the BX25D. I WANT it to stop and NOT KEEP COASTING WHEN I TAKE MY FOOT OFF THE PEDAL like an HST is supposed to do.
I also mentioned the abrupt stop in the BXxx50 series of days gone by, different machine (NOT THE BX25D that is the topic here) but was just an example of some Kubota engineering mistakes.
I've owned several HST Kubotas and this one, the BX25D, is WRONG, flawed, not right because it doesn't stop when the foot pedal is released, it keeps coasting right into the truck that I'm trying to load a two bottom plow into the bed. It stops when the brake pedal is pushed which has been moved to the left side from the right side where it has been for the 12 years that I've owned HST Kubotas.
I saw No flip flopping in my post. I did NOT LIKE the ABRUPT STOP in the BXxx50 series in reverse that no other HST Kubota did (One I owned several years ago a BX2350 not the BX25D I own now). It would snap ones back/neck and COULD NOT be feathered out with the pedal like all other Kubota HSTs could be done, feathered out to a gradual stop.
I DON'T LIKE THE COASTING (TALKING ABOUT CURRENT BX25D NOW AND NOT THE 50 series of bygone days) in forward when the pedal is released on the BX25D that I now own because no other HST Kubota that I've ever owned has done it.
Does your BX2370 keep going when you release the pedal on a level surface or slight decline or stop?

Yup, my 2370 still moves after taking my foot off of the pedal, which I don't like. My response to you post was just trying to understand you better.

I think my pedal needs to be adjusted a little, so that it goes back to neutral sooner... however that wont fix the "still goes downhill" issue. That must be some sort of HST adjustment. I would like to figure that one out. There just doesn't seem to be any "locking" of the hst when in neutral, which there should be.

. . .
Per workshop manual its called Dynamic Braking. There is an adjustable Hst spring.
Turn on engine, full rpms, 2wd and in high range.
On concrtete level ground at full speed, let off and it should stop at 9.8'

. . . .

I know you guys are talking about the BX25D but I checked my BX2660 tonite and in high range, full rpms, 2wd and full speed, it stopped at about 8 feet. I've been unhappy with mine at lower throttle settings, which is where it doesn't stop as quickly as I think it should or as quickly as my BX23 does.

Does yours keep rolling at slow speed in low gear on a flat surface after removing your foot from the pedal? That's what the new BX25D IS DOING, still rolling in turtle speed and not full out speed. Even at a slow crawl it will keep rolling forward when foot is removed from pedal. That is wrong for an HST.

I had a BX2660 along with several other BXs and even a earlier BX25 before they were labeled BX25D and they ALL stopped when I removed my foot from the pedal in low gear at low ground speed. Also all of the Bs and the L HSTs stopped when I released my foot from the pedal in low speed. At fast speed full out that one continues to roll a few feet isn't an issue or problem for me since I am not expecting to fly up to the side of a truck to dump a load or a 2 bottom plow but I want/expect the HST tractor to STOP at slow speed when doing more precise work and my current BX25D doesn't, It keeps coasting until I mash on the brake which I've rarely ever used on an HST Kubota other than when I stop it or get off the tractor and lock the brake down.
On a hillside of which I have many my previous HSTs will stop when I let off the foot pedal and may creep a bit after it stops until I touch the foot pedal in reverse or hold the foot brake down if I'm going to set on the tractor for awhile on the side of the hill and to me that's OK and normal.
Not stopping on level ground at slow creep speed when the pedal on an HST is let off is NOT normal to me. In fact I'm saying it's wrong, from my experience.

Sounds like you would be just as well off with a gear transmission if you have to brake at each stop. I have only driven 3 Kubotas (my daughter 2920?, my B26 and my RTV and they all stopped abruptly when the HST pedal is released but could be feathered down to a slow stop. I wouldn't keep one that creeps forward when the pedal is released.

Of the 20+ Kubotas one was a B2320 geared. One of my first drives and I let off the pedal and it kept going and then I remembered the clutch and depressed it and it kept going and barely bumped a rental unit until I PRESSED THE BRAKE PEDAL.:ashamed: Yes, that was one of my very short term owned Kubotas and if it had only been an HST I would have loved it instead of hated it. Unless it had performed like my current new BX25D that also keeps going when the pedal is let off. I have taken it to dealer and they adjusted it twice with slight improvement but it's still not right. The fixer is Barlows oldest most experienced master mechanic and he said that's as good as he can do with it. It's a Kubota engineering issue that's going to have to be fixed from "Headquarters" instead of the local dealer fix or until headquarters sends a new part or an engineered fix which they never did with the BXxx50 series abrupt stop in reverse that couldn't be feathered that didn't act the same in forward.
As long as no other buyers/owners complain or refuse to buy them Kubota won't fix them.

Yes it still rolls forward after I release the pedal in low gear, but it seems to have gotten better since I greased the absolute living p!ss out of my HST pedal linkage. I bought it used, and I think the prior owner may have failed to grease that linkage through the hole in the floorboard.

If/when it FINALLY stops raining here, I'll run some tests on my BX2660 in low gear at low/mid/high throttle settings to see how far it rolls after releasing the pedal.

I agree that it should NOT continue to roll forward after you release the pedal. For people who haven't experienced this, it is very much like a tractor that is freewheeling forward after you have mashed the clutch, although not quite as freewheeling as that.

I can tell you that my BX23 has always been perfect in this regard, or at least what I consider to be perfect. I.e., I release the HST pedal and it stops. Period. With no drama.

johnthomas, I d like to see a video of what yours does if you get a chance. Ive read a few of your posts on this and have tested my bx2370 a dozen times. sometimes I think it rolls and sometimes I don't...... im mostly concerned because im more than half way there with my saving towards trading in on a bx25d. should be a lifetime machine for me and the one I really should have bought to begin with but live and learn. I want a new Kubota but maybe I need to look for used or even another brand if there are issues. I might get lucky and they fix this issue, if its systemic, by time i buy or I might get a good one but I kinda need to know what exactly its doing so I know how to test for it.
