Supercrkr, welcome to TBN. It would be good if you would go up to the MY HOME at the top of the page and then choose the personal settings to fill in your profile so that people know where you are, how much land and other information that can help us to better help you.
What specific questions would you like us to offer?
Are you talking about the LK3054 or LK3054XS? The former is an older version, the XS has some nice improvements.
I prefer the curved hood of the CK30, but both tractors are very strong tractors. As mentioned, the CK30 offers more features such as the telescoping hitch arms and stabilizers, tilt wheel, a more roomy platform. I suppose it just depends on which you like better.
I've seen some pretty old 3054's out there that have been well-abused that are still doing great. Of course, it'll be a while before I can say that about the CK30 as it only came out in 2004.
Let us know if you have other, more specific questions.
John
