My little Kubota is the BX2380. Specs note 21.7 max HP. So what does the 23 and 80 or 2 and 380 or any other combinations of numbers refer to? Assuming the X is for smaller than B?
I think that Kubota does a decent job of nomenclature when it comes to both the numbers on the hood and the numbers on the loader. It's not a perfect system though and rarely do we see such a thing. Take GLOCK pistols for example. Their nomenclature is a complete shit show and it shows a total lack of vision re product growth.
Neal Messick has stated that X in the model number indicates that the model is a "crossover" between models, but what's below a BX? Doesn't make sense.
My tractors indicate 60 hp based on the badging, but the M6060 has 4 more hp (net) than the MX and has a four-cylinder 3.3L engine vs. a four-cylinder 2.4L engine. I see the reason for rounding numbers though.
MX6000 > 63.4 hp (gross), 59.5 hp (net)
M6060 > n/a (gross), 63.5 hp (net)
Out of interest, does anyone have a better way of naming models, or does another manufacturer do a better job? For example, I wouldn't be opposed to a number that indicates the number of cylinders in the engine. John Deere did or does do this. Did tractors 50 years have better badging? I do think that that number on the hood should mean something and inform the owner without confusion and provide useful information.
I wonder how Kubota will name new generations of the M4, M5, M6, M7 and M8 tractors. I like the current model names such as the M5-111 or M6-141, but the Gen 4 M7 has nothing in the name to indicate that it's a Gen 4. The current models are M7-134, M7-154 and M7-174.
