Bought it used. Speed/direction pedal did not always return to neutral, Found the "damper" had been removed and "fixed" with a Rube Goldberg setup of springs. DID work OK(ish) but often had to nudge the pedal into neutral. Bought a new "damper", removed the springs and, as I recall, was...

Was looking for a replacement label for B21/TL421, specifically the "directions" lable (with arrows) for the FEL control valve. This one is illegible. While I pretty much know how to operate it, it bothers me and upon occasion I might ask someone to operate the FEL for one reason or another...

Some one might know. I have an old Ebay special "Colossal Tech CUT-50D" with the original "touch start" torch. Wanted to convert it to a "pilot arc" as I may be doing a lot of cutting on rusted and painted steel. The cutter does not have a "pilot" connector, but it does have a built in ground...

I have a B21 for which I purchased an ATI SSQA adapter. Pricey, but very well built, to my amateur eyes. Put it on and tested it with a SSQA attachment I had and loved it. But when it came time to being cutting and welding the WRlong bucket, which has a curved back, for whatever that's...

Need to find a good relatively cheap tool to help remove a cylinder end cap, with "radial" holes, picture attached. I have tools to remove the ones with holes "on top". Seems like Kubota chose hole sizes a bit small for most tools for that cylinder diameter. Bought a "gear wrench" set on...

Title says it all. Found the pressure on my B21 to be about 1800 psi and adjusted it to 2000 psi which is the "factory spec". From what I've read it is very common for machines to be found 200-300 psi lower than factory and was wondering why?

Made up a simple pressure gauge to check relief setting on my B21. A simple T fitting with 5000 psi gauge and a QC coupler on each end. It does work and show pressure, indicating about 1800 when the relief actuates. About what I expected and will, unless advised otherwise, adjust the relief...

Getting ready to convert pin on FEL 4n1 bucket (Wr Long on B21), which has "hard wired" lines from the solenoid valve to the 4n1 jaw cylinders to SSQA. Obviously, the thing to do is add QC couplers, And replace the well abused original hoses. I bought it that way, in case you wonder. I see the...

Always wondered about the bucket "self-leveling" on this machine. While reading up on it in the owners manual (imagine that), it said it was important not to "interfere" with the self leveling action. Got me to thinking what that meant, and as I looked more and examined the machine, found the...

When I hooked up the TnT for my B21 I got a two spool monoblock without detent/float. Some have suggested I should have a detent/float for both the top cylinder and the side cylinder to aid making a smooth level finish. I am considering changing the valve, or getting the detent and spool for...

Slight itch has become "a need to have". Anyone know of (reasonably priced, good quality) SSQA conversion kits for B21/TL421? Currently there is a WR Long 4n1 bucket on the front in place of the Kubota bucket, which I never had. I found this and wondered if anyone has comments about the...

Looking for a (reasonably priced) replacement for a HYVAIR d03s-2c-12d-35 for my 4 in 1 bucket control. I suppose any solenoid operated hydraulic valve of similar flow rating would be OK if I had to. Or even non solenoid, but I have not thought that out. Seems toward the end of an afternoon...

Got a B21. Seems to be a "screw and jam nut" adjustment for hydraulic pressure. I was going to cobble up a pressure test rig that I would plug into the backhoe supply, "in series", so the BH could still operate, if I chose to do so. The test rig would be a simple "T fitting", a 3000 psi...

I saw a post in a Kubota FB group about EA declaring bankruptcy. Thought it was BS as it originated on a TYM group, but the EA FB group is "paused" as of 2/1/2024 Their web site appears unchanged. I called but could only leave a message. Anyone know the real scoop?

Replacing the HST damper. The "neutral centering" seemed a bit "loose" to me, so decided to take a look. Gotta remove the right floor pan to get a good look. Got the pan "free", by removing a number of bolts, some very reluctant, the brake springs and the parking brake lever. But . . . I...

Any advice on how to change the Damper for the HST pedal linkage on a B21? None is currently installed, as the PO replaced it with an arrangement of springs. At the time of purchase I had no clue that was not "stock". Pretty pricey for a shock absorber and wondering if I really need to replace...

While taking things down to remove boom cylinder for reseal, took on replacing some bushings in that area as I felt there was "too much slop" as I moved the boom. Seemed like the pivot and such were a bit free. I found two bushings, or "inner rings" on the swing frame where the boom pin goes...

Planning to reseal boom cylinder. The BH is in the "removed from tractor" position, which makes it a task to remove the boom cylinder. The swing cylinders are out as I resealed them and figure it is easier to move the boom, etc, when they are not in the way. I expect to replace the...

FYI - The Kubota cotter pin, p/n 75599-53266 (7/32 x 2 1/2) that is being supplied in a sealed and labeled package is actually only 1/8 x 2 1/2. It is about half the thickness of what it is spec'd to be. I've informed the online dealer and they are looking into it. Yeah, I could get cotter...

pondering replacement front tire and looking at Messick and others, find Kubota #32721-50500 ASSY TIRE/WHEEL for around $200, which is more than half what the cost of a single wheel and single tire. And it comes mounted? Am I hallucinating? What tread is on that tire?
