Is it possible to override the load-sensor on the motor of my 21" self-propelled mower?

This spring I purchase the ego 21 mower later to find out that the SP model was soon to be released so I exchanged it. My only complaint so far is I wish I could manually override the load sensing motor. At times I fell it lacks the suction of my gas mower. Possibly something ego would consider in future models.

I am also a happy owner of the 15' trimmer and CFM530 blower.

I think this would definitely be worthwhile, especially for those who have smaller yards and/or those who just desire maximum performance over extended run time.

I forget which mower it was I saw, but one battery mower had an "Eco" mode. I'm not entirely sure what that means, but I have to assume it's a lower blade speed or some sort of variable speed system to conserve battery power.

If Ego had both a "variable power" and a "full power" mode the user could select whichever mode worked best for their conditions.

20 would be enough for my lawn!

I blame marketing honestly. Peoples first question..what is the run time? We do it to ourselves. But yeah. Having a power selection mode is critical. Its just software. Hell. I could write the software for that motor controller. Its just a PLC. Ones and zeroes. 00010110110010

I think this is exactly the problem.  Moving air takes energy.  Move more air, shorter run time.  Then, instead of complaints about lack of vacuuming power (and possibly rows of clippings) EGO would be dealing with complaints about short run times.

BUT, Ego doesn't really suffer from a lack of power potential. The upcoming snowblower appears to hold up to 15Ah (2x 7.5Ah batteries), just based on what is currently available.

And if you consider how small a possible future 23.2Ah battery appears to be...



...I dare say 15Ah might seem puny compared to future generations of Ego tools.

Let's hope in the future Ego focuses on increasing max performance first, and then worries about power economy and run time by making bigger, badder batteries and chargers.

If you don't count our resident madman Jacob (the guy who push-mows 1-1/2 acres!?!), I think the average person is going to see a one hour run time as a pretty practical limit. And by that I mean, the average person with a yard that takes much longer than an hour is going to have some sort of ride-on mower.

That's not to say we don't need bigger batteries, it's just to say that once we get to the point where mowers are lasting longer than an hour on a charge, performance will be of greater importance than efficiency.

For many people I would think we're there now, and lots of people would be happy with a mower that slaughtered their lawn and mulched like a Cuisinart even if it only ran for 30 minutes. These are the people who would gladly opt for an extra battery to get the job done.

For the record, I fall into that group. :-)

It's a problem with my second gen Prius as well. There should have been an all battery option, a no battery option etc... As the technology evolved companies discovered that there were times that their customers wanted/needed full or no eco, or a combo of both. The same here. The TURBO button on the blower is awesome because I leave it on 80% of the time. However, if I didn't have a couple spare batteries I wouldn't want to kill my battery. The point is that it's nice to have the option. Jan does her lawn one way, I do it another. Same with the mower... It would be nice to have full on mode!  They hopefully will make different modes and options. Clearly, with the SP mower, it's nice to change speeds. It would be equally nice to rev the blade at 10^10rpms!!!

Options are always good!

I think what happens sometimes is the "Apple" mentality of designing things that "just work". For most people in most situations, yes, just working is good. But for those who want a little more or whose expectations are a little higher, "just working" is not enough. And then there are those cases where the users situation is just a little more different than average, and it just "barely" works.

If the mower had three settings, like Eco (current mode), Normal and Performance, where each one had a higher and higher minimum speed, owners would quickly be able to figure out which mode suited them best.

The challenge then becomes marketing. Most people are BAFFLED by options. Sad but true, most people would rather watch re-runs of some poorly rated sitcom than take the time to understand how something works... even when researching a major purchase like a lawn mower.

Wow. You already wrote this. Lol. I just made the same comment above. Funny.

Yeah, the newest entry isn't always the one at the top/bottom. :-)

I'm all for options.

An ironic statement about Apple.  One of the things that made Apple great (in years past) was that they allowed users to customize their devices.  Now, as you note, any meaningful control is locked away.....

Having said that, I'm typing this on an iPhone. :-)

The Apple approach is good enough for me as far as phones go. A buddy of mine who's an IT guy just shakes his head wondering what's wrong with me. Different strokes for different folks, and I can totally see his point of view.

But all of this did in fact remind me that even Apple put an "Eco" mode into iOS. The Low Battery Mode shuts down non-essential stuff to keep things going longer. Looks like Ego could do the two-mode thing and still keep it simple enough for the old folks looking for "where we get apps". ;-)

Yeah, the 21SP definitely lacks suction (do I sound like Dyson?).  Of the 5 Ego products I own, MY fav is the blower.   It has a tremendous amount of power--so much so that I can blow things off of wet grass.

Agreed, the blower is one impressive tool!

I think it's Tesla that has insane mode. There are ways for even non-engaged people to figure it. I am with you on the Apple mentality. I know I am one of the few people to actually read manuals anymore.

Didn't you mean "ludicrous" mode?   :)

Yes, I was underselling with "insane". Ha. So, yes, Ego, my snowblower better have Ludicrous mode with a run time <1min

It will scare the snow off your driveway. Awesome...
