We just moved into a new house. The house has a nice lawn in the front but in the back yard it apears that nothing was done after the final grade and large amounts of grass and mics weeds have sprung up over the last 3 years. We would like to do the work our selfs but dont know were to start. Can we use one of the powered bobcat landscape rakes and just scrape all of the grasses and what not off the top put down some top soil level it up and seed? Or do we have to do something else any help we can get from here would be greatly appreciated.
