And if you don't want to irrirgate, plant some trees to give the lawn afternoon shade and add organic matter to the soil.

I saw your other post that contained your plan, and you've got it all down. You know exactly what needs to be done and you're prepared to do it. You live in a climate where KBG can do very well (New England, i think I saw). You've already purchased the seed, and you've lined up all the equipment. I think it'll turn out just great. Sure, you might want to overseed next year, but that's probably the worst possiblity. Most lawns take 2-3 seasons to really establish themselves anyway. You've done your homework, you know what needs to be done, and you're prepared to do it. Go for it and don't look back. This time next year, you'll look back and have a good laugh at yourself. Cheers!

Only one week ago? Well some of your seeds have probably worked into the soil from all the rain. Any seeds on top of the ground will probably be sucked up or moved by a mower with a bag. Since it's only been a week you can get by with mulch mowing. I would probably mow it pretty low, like 1.5 inches, but not all at once, waiting a few days in between mowings until you get it down to that level while observing the 1/3 rule. Hopefully at that level you can get by without a mowing for a few weeks.

Thanks to everyone for the reply and information! This is what I learned so far: 1. The seed distribution method of a Bluebird or Billy Goat Over-seeder is very inaccurate. 2. Drop spreaders are more accurate then broadcast spreaders. My almost classics, 24 years old ScottÂs PF2 drop spreader is most likely as accurate as any on the market today. 3. The spreader should be calibrated prior to use to ensure accurate seed distribution. 4. Seeding an acre 43,560 sq ft with a 20 inch wide drop spreader is a job for the wife. 5. If the seeder is in the front of the over seeder  the seed will be sliced in the soil. 6. If the seeder is in the rear it will be distributed on top of the sliced soil. 7. It is recommend applying grass seed in 2 directions - North-South then East-West 8. Kentucky Blue grass is the best spreading grass. Thanks Again! Stay in the fight for Christ! Andy
