Thanks so much for all of the help! It does look like a Kubota 305 -- And thanks for all the links - found the service manual and parts lists and I've got some reading to do on the other links - very helpful. Ya'll are awesome!!!
Can anyone tell me the model number of this Kubota? It seems to have no identifying numbers and we need to get a parts manual. Thanks for any help. (it's 4 wheel drive)
