Hi TexasHorn,
Sounds like you're looking at horsepower range or $$$ mostly for comparison?
More fair comparison would be Kubota L3130 to the 3120..........OR..............the Deere 3203 to the L3400.
At least those are the "intentions" manufacturers have in designing the tractors.
L3400 and 3203 are "economy" lines with less features, esp. hydraulic capacity...
3x20 and L3x30 are "flagship" mid-size lines, that are intended to be more able and user-friendly... heavier, greater hydraulic capacity, more ergonomics/comfort in design.
If pricing is similar, then you would be getting more machine in the 3120 than the L3400... little less horsepower, but more weight to use the horsepower you have.
I have a 3320 and love it... a joy to operate!
