What size lawn do you have?

Fairly normal urban sized lot. Largest area is appx. 40'x60'; other
about 20'x100'.

Could you use a blade on a smaller Bobcat and
even things out if need be? How about one of those things with several
spikes that dig into the ground. Not sure what they are called but he ones I
have seen are usually pulled with a chain and used on smaller areas and some
ball fields.

Sounds like either of those methods would pretty much destroy the
existing lawn, right? I'm hoping the least destructive method possible.
I was wondering if a dethatch job would effectively remove the tops of
the dirt clumps.
