grass left standing

I have noticed lately that my mower has been leaving a lot of grass standing in its path causing me to spend a lot of time mowing areas twice. I have a Husqvarna RZ5424 which is giving me the most trouble. The dandelions seem to be the biggest problem. I also have a Scag advantage 36WB that performs much better over these areas leaving virtually nothing standing. I have sharpened the blades on my RZ54 twice already this season and not at all on the Scag. Any suggestions?

If you haven't already, make sure the underside of the deck is cleaned off. I've had countless things stuck in the mower and after i scrapped it off, it would cut much better

those dandelions and some other weeds can be tough to cut...they tend to just bend over...make sure the blades are sharp and slow down..if you go too fast it will just go right over them and bend them over instead of cutting them

Check the pitch of the deck might be to flat
Front of blade should be half inch lower then the back
Check RPM of the motor

You want sharp blades, I put sharp blades on mine every time fuel goes in the tank.

Check and make sure every blade is on tight, and that none are upside down.
Also I'd check the belt and its tension, a loose or worn belt can do it some, too.

When cutting, make sure the blades are engaged and that the deck is down and out of the transport position.
Ground speed while mowing needs to be well below transport speed.

You want the blade sharp enough to catch and scrape your thumb nail - that's how you tell if a blade is sharp enough.

1/2in is a lot. It's going to depend on the length of the blade.

This seems to happen a lot this time of year. Wet grass, over grown grass, to fast of ground speed are some common factor's that will cause grass to be left uncut. Also how old the mower is. Mower decks do get worn out and do not cut as well as old decks.
