Wrong answer.

The "solution" to having backups go back quite a ways is much simpler, and doesn't involve monkeying around with manual deletions or hacks.

Simply buy an external drive that is SIGNIFICANTLY LARGER than the one you're backing up.

That's it! Time Machine only makes ONE master backup and then just "adds what's changed" in supplement. If you have, for example, a 500GB boot drive, a 1TB external should easily be able to go back six months or quite a bit longer -- maybe years, depending on how much material you change each day (hint: most people -- nothing much).
