I'm working on a brand new lawn, about 1 acre or so. Last fall i dormant seeded with what i would call very good results. At that time i harley raked it and put the seed down with a Brillion seeder. Smoothed out the yard fantastic. Unfortunately though with the slope of our lawn, the snow melt and also the MAJOR spring rains (or downpours) we have had, i have some drainage ruts. It's been difficult to control. As i fill the ruts by hand, and seed, the downpours between the dry spells create a consistent washout. However, today my irrigation system will be completed , and i think if i am to get some decent dryer weather the seed will begin to take and help control the washout areas. I guess my real question is, other than hand filling and smoothing the drainage ruts, the rest of my lawn is not exactly smooth. I take a beating when i mow! Understanding that i don't have real thick grass yet, and that i am going to be overseeding, is there a way to level out my lawn without completely tearing up what i've got started so far? Would re-harley raking take out what i've got growing? Couple neighbors have suggested some sort of drag, but it's not like i have loose soil laying around to drag. What's the approach for a project like this? After over-seeding, will a thicker lawn eliminate the rough terrain that i'm experiencing? I've attached a couple pics to show the current growth if that might help. This is my first "lawn from scratch", so it's a new territory for me. Thanks for any advice you could give.
