Preparing for summer

With summer on the horizon and lawn care duties ready to start, I think I need an upgrade of my lawn mower. I was thinking of something along the lines of a 900 CC Lawn Mower. Now to make this economical, I think cetan and I should get together on this one. We would do my puny 1/4 acre lot in about 1 minute, then do his larger plot of land in 9 minutes. What do you say cetan?
