With new customers, if the grass is really high when i cut it for the first time, i highly suggest to them that i bag it, so that the clumps of grass dont kill the grass. bagging charge and disposal fee incur, though.
My set up:
-2007 Chevy 2500hd 8.1l 4x4
-7x18 enclosed trailer
-Grasshopper front mount 61", gravely 52"
-36" Gravely Walkbehind, 21" exmark push mower
