Got a few aeration jobs this month, did 'em this past week. About 32k total, did them twice, 90 degrees apart. This is the first time I've used a WB aerator, always used the tow-behind. I rented a Ryan Lawnaire IV. Did a real nice job, everyone was pleased. But I have NEVER had my butt kicked by a machine like that one did. By the end of 23k I was ready to roll over and die. Luckily it was getting dark and I could put off the other 9k till the morning. But MAN!!! This is my first season, and I plan rapid growth for next year, so I'm hoping to be able to justify a zPlugr sometime in 2006. To all you guys who run WB aerators all day long, I take my hat off.
