Yes it does seem to be a prevalent issue with these units . Tomplum has stated that usage of Gator Blades , has in some cases improved this condition with trial and error varying or staggering the deck height . It may very well be caused by the different mower deck design on these newer Honda,s . I have a 5+ yr old 22" Toro Recycler FWD single blade design which cuts great . A neighbour of mine has the 22" Super Recycler RWD which has the slightly larger engine , which I would recommend if you have a larger Grass Plot or tend to grow your grass longer with mixed clover situations. Both units are under the $500.00 price point still I believe . The downside are the Easy Start EPA Carbs with Thermal Bimetal Chokes which require Religious use of Fuel Conditioner , especially with Ethanol Fuel Use , I prefer the Old Butter fly Mechanical Choke or Purge Button Style Carbs , but I Regress lol .

Analyze your mowing habits; are you waiting too long between cuts and trying to cut more than 1" of grass at a time? Are cutting wet grass? Do you have your wheels set higher than 3"?

Look at the mower; are you sure the wheels are all set at the same height? Are the blades on upside down? (This may not be possible with a Honda, just saying). Is there any grass slime build-up in the deck?

If the wheels get wet, it is too wet to cut. I don't care if its just a little dew, you have to wait until its dry.

Cutting too much grass at one time always results in poor performance.

Trying to mulch higher than 3" allows the blades to push the grass down instead of cutting it all. This is because the blades are also fans for vacuuming up the grass when bagging or discharging. When mulching, the air has nowhere to go - when the deck is too high it escapes and pushes the grass down as it goes.

The Quadracut dual blade system is great but can 'puree' the grass when mulching, producing a green gel that sticks to the deck and gets in the wheel tracks. It has to be raked out or the grass dies in the wheel tracks. When I was using a Honda, I removed the upper blade, using only the 'regular' blade which fixed that problem.

The mowers and engines are so advanced and reliable that its worth adjusting your habits to accommodate what it needs to do the job you expect. I got a discharge chute for mine for those times when you're forced to cut grass that's too tall. This attachment spread the discharged clippings out so well that sometimes I didn't even go back and bag it a few days later. You have one of the best mowers available; you may still have to use it intelligently to get the most out of it.

Thanks for the suggestions. We never mow when it's wet and never take more than 1 inch off. The mower is set at 3". I will have to check the blades to make sure they are on correctly. I know they are sharp. I will try removing the upper blade and see if it helps. Thank you!

No Mower is designed to cut wet or even damp grass while in mulching mode . The current trend with the New Honda Dome deck twin blade units is customer complaints . Cutting grass of 3" height or greater is pushing the envelope for any walk behind mulcher . Your getting into the Physics of cutting rate to mower pace ratio . Think about it ? I believe Sax has identified correctly the Proper Mulching Protocols ! I have never had an issue with any uncut blades with any mower , only sporatic clumping when forced to cut overly tall grass due to previous inclement weather .
