Not enough lift

This will be the 3rd season using the 7.5 Ah 21” self propelled mower. As a bagging mower it’s fine. For mulching or side discharge, it leaves a lot to be desired. In mulching mode, you can only be cutting a minimal amount or you start leaving clumps on the lawn. The side discharge is next to useless. The chute is poorly designed, and the mower doesn’t generate enough lift to blow the clippings out where they would disperse. I have tried the high lift blade with only a slight improvement at the cost of reduced battery life. So I end up bagging my clippings all the time. Since there is no “throttle” adjustment, isn’t it supposed to increase power when there is increased resistance?

I agree with your assessment that the mower doesn't mulch finely and leaves clumps on top of grass, especially if it's been over a week since the last mowing in summer when the grass is denser and growing fast.  

I tried the high lift blade, but it increased the clumping, leaving more clippings sitting on the top of the grass...and seems to strain the mower motor, and makes it much louder.   

Sharpening the blades doesn't make any difference with the clumping either.

If I overlap or go over those spots again, the clumps disappear.  I don't mind doing that, since I enjoy using the mower and my yard is small.  It wouldn't be fun with a big yard, however.

This is the first year after two years of owning the mower that used the bagger.  I really like the small, lightweight easy to remove bag and the way it fits lawn bags for easy disposal of clippings.  I will probably keep on bagging from now on to remove more weed seeds and not have to overlap or go back over the clumps.
