Wondering what your Kubota model number means? It’s actually a code assembled from several parts that refer to different things. Here’s what each letter or number means from left to right.
Example: In this example, tractor serial number was 900 was built in 1981 because it is after the first serial number for 1981 but before the first number for 1982. The list only shows the number from the first tractor built in each year. Unless you happen to have the first first tractor off the production line, then your particular number will not be on the list.

Kubota Series Identification
The model number starts with a letter, which designates which series the tractor belongs to. Kubota offers only a few current series classifications: B, L, and M.
Kubota B Series – 20hp to 30hp subcompact tractors designed for lawns and small farms.
Kubota L Series – versatile compact tractors for heavier work, the L series ranges from 30hp to 60hp
Kubota M Series – heavy-duty workhorses designed for commercial use, the M series boasts 40hp – 145hp.
X Variations – if any series identifier is followed by an X, it is the smallest tractor in the line. BX tractors are 20hp, LX tractors are 30hp, and MX tractors are 40hp.
HP Numbers
The next two numbers designate horsepower and it’s a little deceptive. Horsepower ratings are not exact; the actual hp is a couple of points lower. You’d assume the Kubota B2301 model, for example, has 23hp, but it actually has 20.9 gross hp. Still, it’s a good approximate.
Chassis Numbers
Finally, the last two numbers on the end identify the chassis, and that’s where all rhyme and reason go out the window. For the last 15 years or so, the numbers have been more standardized. Before that, it’s anybody’s guess.
If your tractor is less than 15 years old:
- Older B Series chassis numbers are 20 or 50
- New B Series chassis numbers are 00 or 01
- BX Series chassis numbers are 50, 60, or 70
- Grand L Series chassis numbers are 30, 40, or 60
- Standard L Series chassis numbers are 00 or 01
- MX Series chassis numbers are 00
- M Series chassis numbers are 60, X or GX (X and GX are 100hp or higher)
Nothing confusing about that…
Note: These are identification codes for Kubota USA. Kubota series tractor identification numbers in other countries are slightly different. For example, if you run across a listing for a Kubota M4072 with 74hp, it’s a European model.
Tractor Variation Codes
Once you get beyond the basic model number, you may find codes in your paperwork or painted on the fender that provide extra information for that specific tractor. This information includes whether it’s two wheel drive (2WD) or four wheel drive (4WD), type of transmission, whether it has a cab, and more. Naturally, the more specialized the tractor, the more possible variations might be identified. While there is some overlap, in most cases, letter codes are different for the different series. For example, in the B series, 2WD is indicated by the letter E, and in the M series, an F identifies 2WD.
Position also matters in some cases. Letters that come at the end of the string after a dash can have a different meaning. TLB is tractor, loader, backhoe, while -T indicates that it’s a specialty tractor made for towing (primarily used in airports).
A few basic codes are generally the same on all models:
- C means cab model
- CS means creep speed
- D or DT means four wheel drive (4WD)
- E or F means two wheel drive (2WD)
- HST means hydrostatic transmission
- GST means glide shift transmission

Putting it all Together
Say you’re looking at tractors and you come across a L3560HSTC-LE. Now you know it’s an L-Series, 35hp, on a #60 chassis. It has a hydrostatic transmission, a cab, and it’s a limited edition. Simple! Ok, maybe not so simple, but at least you can figure out what you’re looking at.
One last thing to note. Attachments have their own identification codes that have nothing to do with the tractor itself. If you see a code on an attachment, it only refers to the attachment.

Kubota Tractor Corporation pays their marketing department a lot of money to come up new model and series numbers each year. These new numbers can be confusing and make you think you need to be a Navajo Code Talker just to understand what you’re looking at. The good news is that you don’t have to be. In this post, we’ll take a look at Kubota Model numbers and break down what they mean and what they can tell you about a specific Kubota tractor.
Kubota has 3 basic tractor model types:
- B : 18-30hp subcompact tractors
- L: 30-60 hp compact tractors
- M: 40- 135 hp Tractors
There is only one variation, which is a X in the model. This X signifies that it is a smaller version of the model before it. Therefore, a BX tractor is the smallest series, or a small version of the B series and likewise, an MX tractor is the small version of the M Series.
Step 2: Behind the numbers
After the series letters there are numbers ex L4060. After step 1 we know that the L stands for Kubota’s line of L series tractors. But what about the numbers?
- The first number after the letter is the horsepower. This is an 40 horse Compact tractor.
The Second number tells us what chassis the tractor is on. This is where things can get a little tricky, especially if you’ve got an older Kubota. For the last 10 years the Grand L Series Kubotas have been denoted with 30 a 40 or a 60 after the number. The standard L Series has been 00 or recently 01. For tractors 10 years or older, please contact your dealer for series information.

Therefore, a L3901 is a 39 horsepower standard L tractor. Whereas the L4060 we looked at before is a 40 horsepower Grand L Tractor.
- The BX Series have ended in 50 60 and the most recent are 70.
- The B Series ends in 20 and 50, the 50 is the larger chassis.
- The L Series presently has 01 (standard L) and 60 (Grand L- Larger Frame).
- The MX Series is 00.
- The M Series is denoted by 60, X, or GX- These are the big 100+ hp tractors.
Step 3: The Fender Letters
On the rear fender of the L Series and up there are usually 3 letters, 4WD, HST or GST. These denote which type of transmission the tractor has.
4WD: Stand L Gear Drive*
GST: Glide Shift (Only available on Grand L Models)
*Note: All B series tractors have 4WD but most come with a hydrostat transmission.

Step 4: Loader Numbers
A lot of people only see the loader number on the tractor because the loader covers up the tractor numbers. This is common, don’t worry if you’ve made that mistake. The loader numbers are the easiest to figure out. Basically it’s LA which stands for Loader, then the lift capacity in kilograms. So a LA 1154 can lift 1154 kg. The easy way to guess that in lbs. is to double the number, so a LA 1154 can lift roughly 2,308 lbs.
