Side discharge clumping

I have owned my Honda Harmony 2013 Mulching mower (rider) for years. Now that my lawn is well established, I get terrible clumping out of the side discharge. I no longer use the mulching kit. I now shoot it out the side discharge with the discharge cover off. I mow my lawn 2 times each week and need to know what I can do to eliminate the clumping.

I mow when it is dry, mow at ~4" high and alway keep my deck clean. I do however still use the original mulching deck and mulching blades.

Here are the blades I use: http://www.jackssmallengines.com/hon...58h60_big.html

Would regular blades help?

Well not sure how much help this will be, but, you did state you had the mulching deck and blades still on. If your mulching kit came with baffles and blades you should remove the baffles and go back to the original blades. The baffles in the deck essential redirect the air flow so that each blade is isolated. There should be minimal air flow across the deck with the baffles in place. Removing the mulching cover alone will not convert the system back to an effective side discharge unit.

Dry grass, does not clump. Needs to be drier.

I'm not sure how to make my grass any drier. The only moisture is from the grass itself, there is none externally when I mow. My neighbor mows their lawn later in the evening then I do and there's is longer than mine (they mow once a week) and they don't get any clumping. I'm pretty sure it's something with my mower set up.

My mower height has settings from 1-7 and I mow at 6.

What does this statement

"I do however still use the original mulching deck and mulching blades."

mean?

If you have a mulching deck with an open side chute or mulching baffles installed in the deck your air flow out the side chute will be appreciably diminished which could be the cause of your clumping. A mulching deck will be designed to circulate clippings around the blades and not have a strong air flow out of side chute which you have opened.

I am assuming that mulching decks are engeneered differently than standard side discharge decks.

I'll have to look and see if there are any removable baffles. I have not done this yet.

Thanks

RPM's

Make sure your engine is turning the maximum rpm's that the manufacturer recommends. As machines get older they tend to lose rpm's and the governor needs to be readjusted. You can find videos on YouTube that show you how to do this on your particular engine. Good luck, Stan

You know, that a good point. I've had this mower many years and sometimes feel it is at lower RPM's than I remember. I'll search youtube.

Thanks
