i recently bought a new walkbehind. the dealer ordered, and assembled it. i took it out, and brought it back a day later. the deck was tearing up the grass. in other words, i had almost no clearence between the deck and the ground, which in turn caused the deck to tear up the turf . the dealer said it was assembled as per specs. i say, it was not a useable piece of equipment. he raised the deck one "notch", now it is fine. should i be charged for this?
