After reading many of these posts I have come to the conclusion that many "Pros" are not properly equipped or of the proper mindset to do smaller residential lots. I see, in my area, over equipped (z's and big WB's) over staffed (3-4 guys) pull up to a res. and after much fussing about, putting pylons around the truck, unloading z's, and WB's, one guy standing around to blow, trimmer guy with helmit, goggles, AND trimmer guard, finishing one lawn in the time it takes my partner& I to do 3 across the street with 21 LB's and IF I'M FEELING LAZY the 36 hydro. Of coarse they only have one lawn on that street because they can't get the BM's (Big Mowers) into the backyards. Now I'm sure they do some big props 10* faster than we could but if I can cut 3 to there 1 with 2 guys compared to 4 I'm going to be charging less. If you think a 21 is a TRIM MOWER and you come into my area, prepare to be lowballed by a pro. No offense to those of you that stay in the wide open spaces where the z's and the big WB's can roam.
