21" High Lift Blade Review

I thought I'd provide my impressions of the Ego High Lift blade for the 21" mower.  I placed an order on Amazon, and received my blade about 2 weeks ago.  It took just over 6 weeks for it to arrive.  Just to give some background, I'm in Maryland and mow my fescue/bluegrass mix at 3.5" (setting 4 on the Ego).

Lift - There is definitely a noticeable difference in the amount of lift that is created with this blade vs the standard mulching blade.  My lawn is predominantly fescue, and there are areas around my garden beds that get walked on a bit more than the rest of the lawn.  The grass in these areas tend to get matted down, and the regular mulching blade didn't have the suction to bring it back up to cut.  This no longer seems to be an issue with the high lift blade.  The cut looks far more even than before, and there are fewer stragglers sticking up in the lawn after a mow.

Mulching - Here's where this blade just doesn't perform as well as the regular mulching blade.  I read a couple reviews before making my purchase and it seemed like the consensus was that the mulching capability was comparable - however that's not my experience.  The 21" mower is notorious for leaving clumped up grass behind the left wheels as it goes along, but with the mulching blade, this wasn't really an issue as long as I cut frequently and only when the grass is dry.  Unfortunately under the same circumstances with the high lift blade, I still got strips of clumped up grass clippings following the left wheels.  The first time I mowed with this blade I thought maybe my grass was too long or maybe a little damp, but no.  I mowed again yesterday paying very close attention and it started doing the same thing again.  The first mow, I ended up mowing the same areas twice in different directions to break up the clumps.  Yesterday, I ended up bagging.  Both of these methods worked well, but unfortunately they're also both time consuming.  I even sharpened the blade before I installed it.

Noise - Noticeably louder with kind of a deeper roar, but still nowhere near a gas powered mower.

Battery - There was no noticeable difference in battery life as compared to the normal mulching mower.  I feared that there might be due to the increased amount of air that's being moved with the blades, but there was no impactful difference at all.

Overall, I'm neutral on this blade.  I love that it sucks the grass up and give me a nice even cut, but I hate that I either have to mow twice or bag.  Perhaps I'll try side discharging next to see what results I get.

Ray - just an FYI
The HL blade is designed for bagging or discharge.  It is not intended for use with the mulch plug,
So, I would expect your bagging and discharge results to be more favorable.  Although the side discharge on the 21 is questionable design regardless of the blade so perhaps you will not like those results.

I absolutely agree.  For its intended purpose of bagging, it does a great job.  I just wanted to offer an all around performance review evaluating it's pros and cons.  I'm also hoping with the increased airflow that the side discharge will be better as more air is being forced through.

Appreciate the review - was just making sure you knew the back ground.  And as you said some users have stated that they got better mulching results.

Update:  Side discharging with the high lift blade is worse than any other combination.  The amount of grass clippings left in clumps is unbelievable.  

After a few weeks of use, the bottom line is that this blade is great for bagging, and bagging only.  I'd say if you're mowing often enough and only taking 3/4" off or less and you keep the blade sharp, you'll get the best of both worlds in terms of lift and mulching.  Anything more than that and I'd say stick with the mulching blade.  I've taken it off my mower for now, but look forward to using it again in the fall to bag all the fall foliage while I mow.

This matches my recent experience as well.  Great for bagging not so good for mulching.
