Thanks for the answers. I forgot to mention, I already do have a 36" WB. It isn't commercial grade but it does a nice job. The reason for the 48-52" is because my area is filled with 1/2 acre+ lots. My parents have a 1/2 acre lot and it takes me about an hour to do everything with the 36" (mow, trim, and blow). I use to work for a landscaping company and he would let me take the equipment home to do my parents yard. 25 minutes tops with a 48" Walker. That's why I was thinking the 48-52, but you are right, no sense on buying equipment if I do not need it.
And that is a great point about fall clean-ups. I should advertise for that now and make a little money going into the winter and spring months. Thanks for the advice!
