I am looking into installing a new lawn for a friend later this summer/fall. the lawn is prob about close to an acre. existing lawn is full of crabgrass and clover, no quality grass. i plan on killing off the existing lawn. do to all the bumps and uneven ground, i plan to grade the yard with a bobcat as well. What i was wondering is what is the best way to go about breaking up the soil so that it can be graded? i have graded before but never an existing yard, always new construction. Should i use a bobcat bucket to tear up the soil or would a tractor and plow be better? what about a scraping blade on the bobcat? Lastly, any ideas on seeding, fertilizer and herbicides? the lawn is prob about close to an acre.
