Some of my yards are little swamps in the summer. These are in the highest paying places I have so, to not destroy them with the 300# 36" mower, I use my 22" Toro. It will still rut but in little 2 inch wheels not the big ones. I do not charge more because I am already the highest charging LCO in the area and they just expect that I will do everything I can to make sure that they have the best looking place when I leave and not wreck the place. I don't like it but that is the way it is and I will do what ever it takes to get it right!
