Troy Built Mower Not Cutting Adequately

I have a Troy Built 6.5 HP push mower and it has never quite cut the grass as well as I think it should. It clips the majority of the grass blades, but leaves a lot uncut (bent over). So after a day or so, these uncut blades stand back up. I sharpened the first blade and ended up replacing it with a new one, but things haven't improved. It is a mulching mower with 21" mulching blade. Will switching to a regular blade help or is the lawn mower just crap? I have no problem buying a new one so any suggestions would be appreciated (under $300).

 

I think to avoid this, you are suppose to change direction on the cut. Go horizontal one week, then vertical the next, then diagonal, etc. Or if you are mulching, simply go backwards from your last mowing. You want to "untrain" the blades that are growing in the direction of the blade throw.

 

Not trying to be rude, is the blade on upside down? Have a good one. Geo

 

Blade upside down was my first thought too. It happens to the best of us.

If not, my next thought would be engine rpm too low, and if that's good, then I'd wonder if the blade was worn out (the lift of the blade is the first part to wear off and if it's gone, it won't stand the grass up to cut it).

 

No offense taken, but no, the blade is not upside down. It has no problem cutting my Zoysia grass but can't seem to cut the thicker-bladed bluegrass. However, I have been mowing the same direction because it is such a narrow strip (10 feet). Mowing left-to-right would be a royal PITA. Would mulching as opposed to bagging give me better results?

I've decided I'll be getting a new mower anyhow. Most of my lawn is Zoysia and I need a mower with larger wheels because the grass is so dense and the mower scoots around and is hard to push. Any opinions on the Husqvarna brand? I'm looking for a non-self propelled 21" or 22" mower with single-lever height adjustment.
