hi guys been doing research to try and find vin or serial number on the Kubota b2150 I bought (first tractor I ever owned) and I cannot find the number on the engine anywhere but I did find a number on the side of the transmission its b2150d50046 and below that is a small sticker that reads DT can anyone tell me what year and model it is I read that 4 lugs and 6 lugs in the front tires means newer and older my tractor has 6 lug nuts holding the front wheels it came with a blade on back and an la350 front bucket. power steering and it does have four wheel drive. I bought it for 7000. it runs good not so pretty paint is really faded. the previous owner did not help at all and could not tell me what all the levers did but I figured it out I gotta get a manual thanks for any info.
