I had the same choice. i thought about both of these tractors. i bought the L3000DT . the tc 30 is a good tractor i'm sure . i just liked the kubota .
I have been VERY pleased with mine. i have 35 hours on it and have had it three months.
You didnt say whether you were wanting fwd or not. i would highly recommend it now that i have it. it has come in handy alot!
Both are good tractors i think, i just went orange and have no regrets!
