Hey guys. Just got home from picking up my Exmark Turf Tracer Hp 36" 15 HP. I went out and tried mowing my lawn with the mulch kit on it. Well, I was really dissapointed at how it cut at first. Then, I realized it wasn't getting air under the deck, because it was blowing grass out the left side BAD! My dad was pissed because he thinks that if I spend $4500 on a mower, it should mulch better than that, and we're comparing the Exmarks ablity to my 21" Toro. Well, my lawn is really thick (as in lots of blades of grass per sq. inch, THICK!) and I guess that it couldn't get enough air, which is what happens with the 21" when it can't get air. Then, I mowed the other part of my lawn .5 inch higher and no clumps and it's probably just as thick or worse. Someone please reassure me that this air thing is the problem or I'm gonna throw a tantrum! LOL. Otherwise the mower is great! Really fun to operate. Input please guys. I really appreciate it. This is the first W/B that I've ever had. Really hate to get mad at it. Thanks again!
