Lawnmower Best Practices

A few questions on what practices others have developed from experience:

1)  Keep lawn mower running OR turn off/on when turning around and stuff?  Basically, does it drain the battery more to stop the blades when repositioning the mower or to keep it running like a gas mower?  

2)  Deplete the battery fully before returning to charger or doesn't matter?  Always hear a lot of superstitions about batteries and pro-longing or shortening their lives based on charging practices. 

3)  Impact of headlights and self-propelling...  Anyone able to quantify the impact on battery life with the headlights on and/or self-propelling at any of the speeds? 

4)  Cleaning...  Of course it's not recommended to wet the mower but would spraying out the bottom really cause harm?  All the methods of cleaning other than going over the top with a rag sound incredibly burdensome or costly.  This is the least of my concerns right now. 


I've done three mows so far (well, one mow but on three separate charges...  Have a small patch left before this mower has made a complete pass on entire lawn).  Looking for any tips/tricks.  Timed my last mow and battery died out after 33 minutes with minimal propelling at the lowest speed...  And some number of those minutes the mower wasn't even running so...  Really wanting this mower to work. 

Thank you.

1 - Keep running except for extended breaks like going to dump the bale.

2 - Deplete fully if you aren't finished mowing yet.

3 - Hedlights is negligible, self propel is a relatively small impact. Avoiding both may give you a few seconds or possibly a minute more run time.

4 - 33 minutes on the 7.5Ah battery using the mulching blade? That sounds pretty low. I would expect that with a 5.0Ah battery or when using the high lift blade. What kind of grass are you cutting and at what height?

I have pretty dense Bermuda and only see run times that low if I have waited too long to mow and am trying to take off more than 1/3 of the blade in a single pass. Or cutting wet grass. Either will quickly reduce the run time. Keeping the deck clear and the blade razor sharp helps as well.

Luk, with regards to #2, my personal approach is to use the battery, let it sit partially charged, and recharge right before mowing.

Agreed with Mr. Cline, 33 min seems very short unless you're cutting an overgrown and/or wet lawn. Keeping a clean deck and sharp blade is good advice.

I would like to have Ego respond with the official response for #2.
I never deplete it and usually return it right to the charger until next use.

Official Ego advice above

I think any effect of fully discharging every time and or charging before using v after using will be negligible.  Do what is convenient for you and the way you use the tool.
IF you can easily incorporate the extra measures discussed, then go for it and hopefully you get an extra 6 months life out of your battery.  If like me you generally do not plan out your use of the tools, then charge when you are done and have the batteries ready to go when you need them.  The convenience is well worth the possible back end cost of diminished capacity or life.

Thanks - I learned most of it here.

I charge my battery after every use. I have only used the headlights once and didn't notice any additional battery draw. I wipe the mower down with Krud Kutter and water, using an old towel. I use the hi-lift blade and I sharpen it twice a season. This winter, I'll keep the mower in the basement, along with the battery and charger. I leave my lawn at 4" (new sod, 1st season) and I bag my clippings this season only, after that, I'll mulch the clippings.

If you only have the mower, how can you easily discharge the battery completely without holding the lever?  Can the LED lights be left on while the engine is off?

My LED lights stay on when the engine is off. I don't fully discharge the battery because I haven't been able to fully deplete the battery, even after mowing my small (2200sq ft) lawn and my neighbor's slightly larger lawn.

Hi all,

Thank you for the responses.

Bought a new home so the grass was being kept up and not too long.  This is my first lawn mower and first time mowing a lawn so not really sure about what would be too long.

I believe I "scalped" the lawn as I mowed the front with the deck at height 2.  The back lawn, the mower shut down at first on 2 but then I continued at 3.  That back mow resulted in the < 33 minute run time.  I do believe I was cutting more than 1/3 of blade height.

Glad to hear though that 33 minutes is not common.  Hoping to mow again soon with taking no more than 1/3 of the blade off to get a more ideal scenario run time.  I'm using the self propelled model as it came with mulching. 


I am curious though...  Does it drain the battery more to turn it off/on?  I like the convenience of stopping the blade when repositioning and turning it back on when ready.  So it's off for 30 or so seconds then started again. 

By the way...  What's a high lift blade and what is the blade the mower came with?  When should one switch out the blade type?

If you're going to shut it down for 30 seconds it's probably worthwhile, but 10 seconds or less I'd just keep it going.

The HL blade is designed for improved suction while bagging or discharging clippings. If you're ok with your mulching results you shouldn't need it.
