Kubota's sizing explained...

[Big Wave D]

I'm sure that this questions has been asked before, so please just point me in the right direction for the previous post(s).

My question is can someone please explain what Kubota's model numbering systems 'works' out to?

They are usually 4 numbers. I've thought that the first two were related to horsepower, though they don't always seem to match up real well

The second two, I'm not so sure about. I thought maybe it has to do with "frame size", but I can't seem to find a constant for that line of thinking.

Any and all explanations are greatly appreciated.

BX#### Sub compact utility
B####xxx Compact utility
L##xxx Medium utility
GL##xxx Deluxe medium utility
M####xxx Agricultural

# is numbers
x letters


The first two numbers after the letters for size are relative horsepower except some of the old ones like the B7100 etc.

The 3 and 4 number after the letter are the series like the BX has gone from BX2200, BX2230, BX2350 and now currently at BX2360 series. If it is just the two numbers after it is usually a TLB Tractor Loader Backhoe like BX26, L45 etc.

After that you have the letters in the sequence.

DT Gear drive
FST Fully synchronized transmission
GST Glide Shift
HSD Hydrostatic in B series?
HST Hydrostatic

C at end is cab designation

I am sure this is not entirely correct but is close to what I have figured out.

David_Kb7uns,

Thanks for the break down. That is a fair bit of typing you had to do.

Now, for the class review:

So, can a person say that the 3rd and 4th numbers are revisions or builds? Kind of like the British using Mark I,II,III IV, etc?

My L35 has the Glideshift transmission. How does this differ from the FST. Is the FST the Kubota way of saying, manual transmission?

I call the 3rd and 4th number the series, probably from JD. But I guess it could be called a revision. Basically same tractor just a newer "series" with some changes.

The FST is a fully synchronized manual transmission. You can shift it on the go, and shuttle on the go, but you're supposed to press the clutch to shift, just like shifting a manual transmission car. The GST (Glide Shift Transmission) is a full powershift with a power shuttle. There's no need to clutch the GST to change gears or shuttle. It has all of its gears in a line on the shifter and you just move the shifter up through them on the go. The FST has a 4 speed main transmission with shifting arranged in an H pattern like a car, with sub ranges on a separate shift lever.

Baucom,

Thanks for the explanation.

Old habits die hard I guess. I use the shuttle somewhat, without depressing the clutch pedal.

I almost always use the clutch pedal when I'm changing gears. If I just move the shift lever, I come to a complete stop before resume in the gear that I've chosen.

Is this the experience of other GST 'drivers'?

I always just shifted on-the-go, clutchless, & did the same with the shuttle at lower speeds.

I don't clutch going through the gears. I usually do forward to reverse mainly out of habit and it can't hurt right. I'm a work-it-hard kind of operator but never intentionally abuse any equipment....even rented stuff.

for most of the tractors, the model tells you the HP and the series of the tractor. My L3130 and L5030, the 31 and 50 are HP, the ending 30 is the Grand L30 series of tractor. '
These have been replaced by the Grand L40 series, so now you see L3240, etc.....
Just take a quick look at the Kubota web site.

The X300 series John Deere mowers can be confusing. The X324 is 22hp. The 2305 is 24 hp, the 2320 is also 24 hp. The 2720 is 31.7 hp and the 3520 is 37hp. The 3720 is 44hp. i used to think the first 2 numbers were the hp but they are just to confuse you. The 20 at the end just says it is part of the 20 series aswell as the 4x10, 4x00, x55, x50 series. How i can remember all this by memory is a story all its own.
