Hey all! This is my very post, and also my first experience with a ZTR which I purchased back in May. Until now, I've always used push mowers, but this year, I have upgraded to a Gravely ZT1734. When I asked the dealer about sharpening the blades, he said something could be lifted up. But I haven't found anything in the manual that instructs me how to do so. So my question is, is there an easy mechanism I can use to access the underside of the blade shaft, or am I going to have to build/buy ramps in which to drive it upon?
