just picked up a 03 36" TTHP, and love it! Need a little help though-the first 5 hours or so, it cut fine, then I started getting what looked like an uneven cut, granted the lawns I have mowed this week w/it have been goat tracks, but the cut definitely was not good. After reading on this site (relentlessly since I discovered it) I bought sdome gator blades this a.m. When I went to take the old blades off, I discovered for the 1st time that it already had gators on it. But instead of being flat like the ones i bought today, they are curved with 4 cutting surfaces on the sharpened side of the blade. I sharpened them, put them back on, just went and cut and the cut still stinks. My question is--what type of blades work best on this mower? what is the diff. in the 2 sets of blades that I now have? And where can I get an owners manual for my new toy? Sorry for the long post--thanks in advance for any help you can give me.
