BX2380 test drive problem.

[Lilguy]

Trading down from a B2601 to a BX2380. Dealer called said it was ready for test and paperwork. Got on it and drove it around the lot. When I let off of the hydro pedal it just kept rolling, freewheeling, forward noticeable, in reverse it would be dangerous. Just kept rolling 20 feet on a flat surface until its momentum stopped. I showed the salesman He said they roll some 4-6 feet. Ive had KUBOTA hydrostatics since the mid 80’s. A B8200 for over 30 years and the B2601 for 3. They come to a controlled short stop always. It startled me in reverse, my wife and I mows grass and and this would tumble into a ditch easily if this happens. Seems there is possibly a Hydrostatic unit issue. I’ll walk away probably, I told the salesman its dangerous with it working like this and call me after service looks at it. I left with all my paperwork.

They bought it assembled from another dealer, it had 3.2 hours on it. I’m wondering if this problem was known and just passed along, defective, to my dealer.

That sounds funky especially given your experience with Kubota hydros. Your hypothesis seems possible as well.....while 3.2hrs "could" have been enough for someone to realize they needed to upsize etc. it seems odd.

As I understand it you have nothing into the tractor. It appears defective. the solution is simple - decline to purchase. Have the dealer get another tractor with less hours or find another dealer who will.

I bought a used, but only 28 hour BX2380. It does the same thing. I did not have this experience when I owned a B3030 several years ago. I'd be interested to know why the tractor wants to coast when my foot is taken off the go pedal. But I don't think it's anywhere near 20 feet. I use the brakes when needed.

Some BX tractors had that concern 4-5 years ago. Appears the dealer needs to start with the pedal adjustment procedure. that's probably the fix. Also, I had a BX25D at the time that worked perfectly, I took it in for its 50 hour service and it came back rolling after lifting my foot off the pedal, it turned out that the dealer pressure washed the tractor and blew some crap into the pedal assembly. I crawled under the tractor and cleaned it, back to normal.

 

[Lilguy]

Salesman called, said charge pump port needed adjusting, he’s just parroting what service said. The forward roll after stop was more than I am use to, 8-10 feet, back up roll was unnerving, rolled like a skate board loosing momentum until it stops. Would have easily gone off my drive and into a ditch. I had a B8200 hydro for 30 + years and 2000+ hrs that stopped dependably when releasing pedal within 6 feet or less. This tractor rolled 20 plus feet like nothing connected.

What does the stated repair mean, obviously something with the hydrostatic assembly.

Many times it’s an adjustment to the spring assembly in the pedal I recall. Google it, lots of info. Mine had some debris blown into it with a pressure washer, and after cleaning it was again perfect. Let them fix it, likely a simple adjustment and fix.

I'll take a look at that. I wouldn't doubt that's the issue after having to adjust the throttle lever after I bought it. The throttle wouldn't maintain position and the RPM's would keep dropping. I found the adjustment spot and tightened it up nicely.
According to the video linked here, tractor should stop within 10 feet if moving in high range at full throttle and then removing your foot from the pedal. I guess I'll have to watch this guy's other video on removing the mower deck to attempt this adjustment. Yay! Kubota BX Sticking Hydro Pedal Fix - YouTube

My bx2200 will jerk your neck off when you release the petal while in reverse. I mean, it will jerk your neck off. I wish it would give a little, like an inch. In forward it has a tendency to roll especially at medium speeds. I have tightened the return spring once and that reduced the 'walk' by half. I think I just need to adjust it some more. What you are experiencing is not normal.

 

[JJZ 109]

Don't recall if the video covered this but mine has a guard below the hydro fan. I didn't completely remove it. There are 2 bolt in each side. I removed the bottom bolts, loosened the tops and just swiveled the guard downward to access the adjuster. Still not ideal to get at but better than nothing.

This is not a sticking pedal. This is a disconnect, that unit just rolled to stop like a car thrown in neutral. Noticeable in forward, down right dangerous in reverse. Anyone know what Charge pump port adjusting is, sounds like a internal hydrostatic issue.

That is the exact issue that some BX tractors had 4-5 years ago. They would continue to roll forward and reverse when your foot was lifted from the pedal, sometimes for many, many feet. It is likely NOT internal issue but a dampener adjustment or something similar. Many, many threads about it if you would take the time to search.

After making the adjustment I find that things have improved in forward mode but not all that much in reverse. But oddly, it seems that the higher the RPM's and the faster the tractor is moving when I take my foot off the pedal, the sooner it slows to a stop in reverse.
If moving slowly in reverse and I remove my foot from the pedal it seems to coast a little further.

Edit: the last link posted by John above greatly improved the forward motion coasting. The part about the pedal linkage, not the spring tension adjustment. Now it stops when I let off the pedal while moving forward. In reverse I still have some coasting but not as much. To be on the safe side I cover the brake pedal when reversing.

 

[Lilguy]

They said they fixed problem so I drove the hour to test it again. Dealer principal handled the meeting. Still rolled on and he knew this tractor deal wasn稚 gonna happen. There's a reason why that unit has an issue, why no one can fix it is problematic.

I've owned 30 Kubotas with all HST but one and only one gear drive. I purchased the famed snap your neck reverse BX2350 (50 series) and after a few months returned it for trade in to Barlows. I did get a financial incentive due to my complaint. Many years later I bought a BX25D which did exactly like you've described. It un nerved me to let off the pedal and it keep rolling especially since many others had always stopped when the pedal was released. I took it to Barlows and they adjusted it but no where near right so returned it and drove it down the hwy from my location to Barlows, about a mile. One red light along the way and I had it in rabbit and top speed and let off for the red light and guess it rolled over 30' and even then had to apply brake. They could never fix it and so good bye BX25D which was defective, period and I knew it from many other Kubotas. The RTVs will throw you thru the windshield if you do quick let off of the pedal but they can be eased off for never using the brake and stop smooth if let off easy.
Move on to one that stops right and never look back at that defective or like the 50 series one that they could never fix so Kubota redone it and came out fairly quickly with the 60 series which stopped correctly in reverse and forward.

Had my B8200 hst for 32 years, B2601 for 3. Both stop almost immediately forward and reverse. Dealer called and said they got it better this time. No thanks, gonna have to try and fool someone else into buying it. Thanks everyone for the input.

I would say "It's not for me". The reason for the test drive isn't to just check a box, it's to make sure you are happy with your potential purchase. If the dealer thinks they are all the same then either try a different dealer or brand.

I think that is a wise move. I checked my BX2200, that used to stop on a dime, and after not greasing the directional pedal for over ten years, it now stops in 12 inches...

I would be afraid of that tractor you test drove...
