Comments on Kubota's engineering

[gabrichter]

I know this has been discussed but want to input my thoughts. New B2930 with 60" mmm adjustments to get level was little bit of work and all links rear and front not at same adjustments - That tells me either tractor links or mmm is not square from factory. Rear link to 2 point arm is a joke, Why couldn't they engineer a link direct off the 2 point main shaft on left side and not use the poorly designed arm that goes over two point arm chewing it up. Also the height adjustment - yes everyone the height adjustment. My kindergardner could design something better, should have a adjustable link lever connected to main lift system like other brands. I did remove and fashioned a plastic spacer shim to go on top of cam and reassembled to take the play out of the assembly and keep it tight as not to move when weight is off cam. Brakes same side as hydro pedals was that engineer on drugs or hung over that day? Other than that love the tractor in every respect so far. My thought on Engineers if they had to work/service what they design we would have well thought out designs on everything we use. They sit at their cad systems designing in the cubicals and never get out in the real world. The few that do change there inefficient designs to work properly.:confused2:

Just my thoughts? I am not an engineer, but I would think that a Corporation as large and diversified as Kubota would have a design team that includes more than just Engineers. Using deductive reasoning, they most probably have teams that are comprised of engineers, mechanics, technicians, welders, and common laymen working as a team to aid in the design and functionality of the machine. Another thought? Is your tractor on a level surface while you are attempting to add your attachments or implements? Perhaps your tractor was improperly put together at the dealer or something has been bent or out of line? I sincerely wish you the best.

That is what an issue is here is with Engineers, Mechanics, Technicians, Welders and common laymen wouldn't somebody speak up on the pros cons of these design inefficiencies? Came from dealer new so would not think anything would be bent or would hope not, May possibly something not put together properly as when recieved tractor was missing entire height adjusement assembly for mmm and had to order all the parts for that afterward and install myself.

HST Problems. I have a 2005 BX23 that has had two transmission failures. The first failure was at 176 hrs and the one yesterday was 89 hours later.

I was using the backhoe for approximately an hour when I return to the storage area and park the tractor outside. At that point everything seemed to be working fine.

After about 4 hrs I went out to park the tractor in the pole barn and experienced problems with the engine wanting to stall when engaging the directional petal. I then checked fluid levels and found everything to be OK.

I then tried again going forward and reverse experencing the same problem. Engine even wanted to stall when the transmission was in the neutral position and engaging the directional petal.

Does anyone have ideas what is causing these failures.

I don't have a MMM so can't comment on that, but I'm amazed how many great engineering ideas there are on these tractors. Like how easy it is to attach the FEL- whoever dreamed that up should get an award. Don't need a single tool, no cribbing to hold it up, total no brainer. Like popping the engine front and side panels off in 5 seconds so it's easy to service. Like the ROPS that folds up and down so easy, makes it possible to get it through a normal height garage door. On my tractor they made it trivial to tap in to add rear hydraulics, some tractors it's a total kludge. The brake/HST issue has been argued to death, rose from the ashes, argued again, so won't comment on that.

You may want to post this in a new message so more people will see it and be able to help you out.
Sorry to hear of your problem and good luck!

I can say from dozens of meetings with the engineering teams, they always have an answer why somthing is the way it is. they do a great job vetting these products and there is a reason for everything. dealers see most products in development with the intent that we pick them appart before they get to the customer. Kubota does this far more than the dozens of other vendors who we support. in my experience their engineering is second to none.

I would like to know why my $25,000 plus cabbed B3030 came with no 12-volt accessory plug, no interior light, and needed wheel spacers to attach chains to the rear turf wheels.

One thing that a lot of people seem to forget is Kubota Corporation Japan is an entirely different entity than Kubota Tractor/Kubota Industrial USA. Most all the tractors, excluding the BXs, are made in Japan by Kubota Corp, Japan. They are shipped over here and fitted with loaders, mowers, backhoes, etc that are made by the Kubota Industrial Division in GA. IMO the tractors themselves are engineered and built to a much higher standard than many of the attachments that are made in the good ol USA. I know for a fact that all the welds on my B3200 are better quality than those on the LA504 loader. Not sure why they can't get their act together over here.

So do you know why they mount some wheels with flat nuts and lock washers, and others with tapered nuts and tapered seats? For instance, look at page 44 of the B2320/2620/2920 manual. That was a recent topic of interest here.
