All, I am not a commercial mower, so my apologies if this post is in the wrong location, but I would like some help. I have some older generations in my family, so for the next few years I have adopted 7 lawn jobs a week (no pay) to help out. Can't decide what mower to get, I have a Chevy 1500 (no trailer) so i will be lifting equipment in and out of my truck bed. Since I have only weekends to do the work, I don't want a light rain to stop my work. Because of this I have been leaning towards pruchasing a commercial 21" mower, since I see the have a higher blade tip speed (i assume that would help in those situations. So I am looking to the pro's here. What do you guys think, I want to blow through these yards fairly quickly since there is not profit, but they are family so want to leave them looking decent. Any help you can offer is needed. Thanks in advance.
