My back yard is Mole Hill City, and it's nearly impossible to push my lawnmower around. How can I flatten it?

Question

Not just get rid of the moles, but get rid of the lumps, ridges, etc.

Answer 1

spreed moth balls around this will drive the moles away, then use a lawn roller to flaten out the yard, you can by one at wallmart or rent one from a rental store.
