I don't know how you guys with the big yards and lots of trees cope. I have an acre plus, with two huge Maples, two huge Ash trees, a 50 foot Pecan, various others including, up until this Spring, a couple of 80 foot Cottonwoods. My method is pretty labor intensive, but I have a mulcher attachment for my mower, and I handle it with that. Sometimes in the Fall I spend a lot of time around the Maples, but eventually I get 'er done. In the Spring is when I have to clean the leaves out of the flower beds, and around the Lilacs. That takes more time than anything, but then I mulch them with the mower.
Not to mention my neighbors have a couple huge Maples, several Pine trees and a Sycamore that with the help of the prevailing winds here, deposits pie plate-sized leaves all over my yard. I find, however, that if I continually lower the cut on the mower over the Fall and the Winter (yeah, I mow several times during the Winter, weather permitting) that by the Spring, I have everything mulched up and the dry grass scalped down to about 2". Ah, the joys of country living.
