I am using a harley rake to finish grading so I can plant seed. Running into some problems: Its rained here off and on for the past couple of weeks making the dirt very clumpy and moist. I am unable to get the clumps out even while making several passes with the harley rake. Should I wait till its dry? How dry is dry enough? Also gravel is all over the property (dirt) were I am seeding. Asked the property manager If they wanted to haul in some top soil can't get him to agree on price is there another way besides bringing in dirt?
