What is the real scientific purpose of aerating a lawn? If you don't fertilize afterwards, is it a waiste of time? What is the ideal deapth to achieve?

The main purpose of aerating is to relieve compaction. It allows air to get around the roots. The average depth of aerating is 3 ". Make sure to use a core aerator that pulls out plugs.

Aerating will help to promote root growth and relieve compaction. When aerating just make sure the soil is moist so you pull good plugs about 2" plugs are ideal.

Silly question but since I do not aerate and many do I have and observation. I often hear people complain about ZTRs leaving ruts and weighing too much. Of more then 300 lawns I have cut with these types of mowers I have only seen this problem on 2 accounts. Is it possible that by relieving compaction that the ground becomes more likely to squish under the weight a 1500-2000 pound mower?

You made me think on that one, hmmm. I would have to say no, because it is only relieving compaction in that spot where the plug is removed. That hole get filled with other dirt and debris. Just a guess, not a rocket scientist though.

I thought it was good to aerate both in the spring and fall, and best if pre and post emerg are applied directly afterwards.

a 1500-2000 pound mowerWho makes a 2000 pound mower that you would put on a residential lawn? That's a heavy mower. I think my Walker only weighs in the neighborhood of 1100 pounds.

IMO the only time to aerate is in the fall (take a look at the golf courses in your area as to when they aerate the fairways) for two reasons.
1. frost is natures way of expanding the soil in the winter, and loosening compaction. Aeration (Plug type) gives the ground more room to expand.
2. The fall fertilizer mixes are usually heavier in the last two numbers, which are the nutrients necessary for root developement. Fall aeration followed by the fall fertilizer application allows the nutrients to get deeper, faster and more efficiently.

My Toro 325D's weigh around that much, so does a Ferris 5000Z Matt. I use my Toros lots of places.

Maybe that 2000# ZTR includes the driver ;)

If the driver is me, then you're in real trouble LOL... :D

In my part of the country we don't get rain from June till October, so aerating is very important to keep water on the turf so it won't run off. And aerating with out fertilizing won't keep the grass green, it needs to be fed.
