Do you like your electric lawn mower?




Astragalo


I need a nice mower. Are the electric ones any good? I don't really want a gas one. I've noticed that there are corded mowers and also ones with rechargeable batteries. Our lawn and our yard isn't that big so I wouldn't really mind the corded ones, but how do they function in comparison to the gas mowers?

Any recommendations?
What kind do you have? I was looking at the corded black and decker one.



Answer
Ive been using electric mowers for over 25 yrs,black and decker best ones,i also have a homelite from home depot.Pros its quiet and requires no repairs,but a blade sharpening every couple yrs.Cons you have a cord and cant use when its raining.make sure you buy one with a button to adjust height on all 4 wheels at once.

why is it easier to pull a lawn mower or a hand truck than to push it?

must explain it by physics


Answer
When pushing a lawn mower, your force is directed towards both your destination (what is ahead of you) and the ground. When pulling it, the force is directed to your destination and away from the ground. When force is directed towards the ground the friction that the force encounters increases, detracting from the force, making it easier to pull a lawn mower in comparison to pushing it.

Just so 'Modern Science' knows, I wasn't the one to give him a thumbs down, and I probably did forget something, apparently leverage. But an attempt to explain it is better than nothing I guess. Just trying to help.
