Why does my mower battery last longer when mowing across the face up a hill instead of up and down it?

If it's not self propelled, I don't know why this would make a difference.  The reason for my question is that I ordered a 4 amp hour battery but already own the one that came with the mower and one that came with the blower.  I'm wondering if I need to keep the full sized battery which was $200/

Not knowing what the terrain looks like and if i understand your question here is my guess. When you mow across the face of the hill your pace is rather constant and the mower deck is for the most part level. when you mow up the hill your pace is altered (up slope) and the mower deck is pushed slightly down (due to angle) causing a somewhat deeper cut. With the reduced speed and deeper cut you use up the battery faster. if i were you i would hang on to both batteries.

Thanks. Makes sense I guess.

I know I will need that extra battery come first cut of the Spring. The 4 amp hour battery only cuts about 60% of my yard.

I wish one 4 ah battery would cut 60% of my lawn. I use one 4 ah battery and two 2 ah batteries. I can mow indefinately. Use the 2 ah battery, then the 4 then a 2 then repeat. I mowed 6 hours straight one day. It was a long day.

Wow, 6 hours? You need a riding mower. If I had a yard that size, I would never consider a push mower..period.

I do have a riding mower. 42" cut. I just enjoy push mowing late at night. Under the moon. Its good exercise.

Good exercise it is. Good deal. Seems like the season is coming to a close I'm sad to say. Only got to use the Ego a good 6 times this season.

I usually cut my lawn and my elderly neighbors lawn, about 2 hours a week.  I love the exercise.  I've used the mower once a week for the past 5 months.  It's been wonderful.  Cutting under the moonlight, well, that's one way to clear the mind.

I can imagine. I never thought I would use the headlights but ended up using them the first time out.


Do you use an extra battery or just wait on the one you have to recharge? I guess waiting is fine during the summer but now I have only a little over an hour of daylight once I get home.

I'm with Jacob.  A full cut of my entire yard usually takes about 12 hours, split across several sessions.  I like the exercise, and listen to books and podcasts while I mow.  I have two 4A batteries, and one will recharge in roughly the same time it takes me to deplete the other (~25min).  Thus I effectively mow non-stop, grabbing a drink each time I switch out the batteries.

25 mins? Sounds like a short run time. I get at least 40 mins.

~25min recharge time.  My mow time will vary from 20 - 40 min depending on how tall I've let it grow :-)

Ok, thanks for the clarification. That makes sense. Sounds like you're cutting constantly. By the time you hit hour 12, it's time to start over again. Lol
