PJ - My 2004 Super Z is having trouble with the finish of the cut. It is leaving "stragglers" or strands of uncut grass so I have to mow each yard twice. I tried using a high-lift blade and also a set of gator blades with a medium lift and it doesn't seem to help either way. It seems ok when I'm only cutting off 1/2" or so of Kentucky Blue Grass but when I'm cutting off 2" or so it's missing a lot and it looks like it's pushing down the lighter crabgrass type weeds instead of cutting them. Any advice on what I should try? I cleaned the underside of the deck and sharpened the blades again to eliminate any obvious causes and can't seem to find a solution. I'm wanting to make one pass instead of mowing each yard twice for obvious time and money savings. There is a gravely diesel that cuts properties near me and he isn't having the same trouble on the same type of properties...help!
