Is there a good reference site for the models through years? I'm more interested in the modern era ( since the 90's ).

Also, are there anything in the model numbers that give you a clue as to what your looking at? For example, I thought I heard that if the model ends with a " 0 " vs ending with a "1 " it makes a difference in trim?

I'd like to learn more about these fine machines. Thanks.

Lots of mis-information for my tractor from that site. L2800; It says produced from 2007-2010. It first came out in 2004, mine is a 2005. Not trusting that site for any information....
This may be why (2) engines made a the difference in years...This is on that site!

This tractor could be equipped with the following engines:

  • Kubota D1403 (2004-2007). It is a 1.4 L, 1,393 cm2, (85.0 cu·in) three-cylinder natural aspirated diesel engine with 80.0 mm (3.15 in) of the cylinder bore and 92.4 mm (3.64 in) of the piston stroke. This engine produced 29.4 PS (21.6 kW; 29.0 HP) of gross horsepower and 24.3 PS (17.9 KW; 24.0 HP) of PTO output power for model with gear type transmission 22.8 PS (16.8 KW; 22.5 HP) for hydrostatic transmission model.
  • Kubota XtraPower (2008-2010). It is a 1.5 L, 1,498 cm2, (91.4 cu·in) three-cylinder natural aspirated diesel engine. The cylinder bore is 84.0 mm (3.31 in) and the piston stroke is 91.0 mm (3.58 in). This engine produced 30.5 PS (22.4 kW; 30.0 HP) at 2,800 rpm of gross output power.

It depends a lot on the model - if you let us know what range you're looking in then people can tell you what the model numbers mean.

Currently, Kubota numbers are generally one or two letters that tells you the frame size, two digits of HP, two digits of series. With, of course, some exceptions to make things harder for people trying to follow along at home.

So, B2601. B-series chassis. 26HP (or thereabouts, the numbers are approximate). 01 series (so often called B01 for short).

L3302. L-series chassis. 33HP. 02 series, which has some enhancements over the L01 series (mainly brakes on the left, electronic clutch on the PTO, and floor mats).

However, in the older series, there were some tricks. So in the 2010s, there were two B sizes - the B01 and the B50. A B2650 was a 26HP machine, but had a bigger frame than a B2601. The B50 series got renamed to the LX series recently, fixing that anomaly.

Going back to the 90s, the numbering was very different. A B7100 was not a 71HP machine, for example, it was pretty much the same size as the current B2601, or the older B2650. So then you're into just knowing what individual models were - the numbering isn't directly telling you useful information.

The other renaming relatively recently was the loader numbers. The loader number now roughly tells you the lift capacity in kg. So a B2601 with an LA434 loader will lift 430kg at the pins. Older loaders this wasn't the case.

The engine models also tell you something. A b2601 has a D1105, which is a 3 cylinder (from the German apparently, D something means 3 cylinder), 1.1 litres. 05 is the series, all the 05 series have similar technology. The L4701 has a V2403. The V means 4 cylinder (again German), 2.4 litre, 03 series is older tech than 05 series.

This is really good information. Thank you for taking the time to write it up ( should be a sticky IMHO ).

I'd like to look around for a larger machine. Just in the information gathering phase at this time. Currently, I wouldn't know what I want or a good deal if I saw one.

This site is a good reference to search people trying to fix their 1980's machines like the L235 and B7100 and finding a lack of part availability on their 40 year old antiques.

1990's are the new 1980's.

Dad had an older M series machine for a while, loved it. He sold it to move to a cab Kioti that was a bit larger (when I encouraged him to start spending some of his money). Both were very good machines.

What sort of age are you looking, what sort of spend? Late 90s I think the M was the model you'd want. Something like an M7030 perhaps. https://www.tractordata.com/farm-tractors/001/3/2/1323-kubota-m7030.html

Looks like in that model the 70 does mean 70hp or thereabouts. The 7030 was replaced by 7040, so the 30 or 40 is telling you the series.

There's an M6030 and an M8030, as you might expect more power and less power.

This list on tractor data gives you a bit of an age and size comparison, there's are some Ls in the similar age range, looks like L4850 L4350 L5450. https://www.tractordata.com/farm-tractors/tractor-brands/kubota/kubota-tractors.html

Depending on what you're doing L might be a bit small. I think at that time the M was as big as Kubotas came - they were traditionally small to mid size tractors, but not really in the large category. At that age if you want bigger than an M probably a JD is safe buying.

I believe all xx40 series tractors are Grand L, which means they have a few additional features.
