I recently purchased a Hustler 42" Fastrak and I am having the worst time mowing. My yard is about 30% in weeds now and when I mow I am always having to make 2 to 3 passes to get it cut level. The row is always in the middle and it is always there. It doesn't matter how slow I mow there is always a line. I recency went to get some gator blades, but they didn't have any and sold me the Toro commercial blades that are the same thing. Those mow just as bad as well. Any recommendations. As far as a cut when I mow straight Bermuda the cut is awesome. I only have issues when it comes to weed cutting.
