[Hidden-tech] electric mowers (solar option?)

[Jim Ussailis]

I, too have thought of getting an electric mower. Mostly because it 
starts, and doesn't require an annual oil change. But...

WQhen you think about energy efficiency, remember that power plant is at 
best about 35% efficient, there are some small transmission losses, and 
the wall charger may not be terribly efficient. And, the battery will 
wear out.

Of course, you could have a corded mower.

Solar power isn't very efficient also (10 to 17%), but the fuel is free and 
non-poluting. You will probably have to leave it in the sun all week. 
That chances a rip-off by the local varmits, which adds to costs.

Hills and stuff. Since you have a push mower you can do an experiment to 
see if you can manage the electric mower on the non-flat. Weigh the push 
mower. Look-up the weight of a potential electric. Add enough weight to 
the push mower so it is the same as the electric (use a brick, or 
concrete block, for example). Then push the push-mower over already cut 
grass. If no work is going into cutting grass, then you should get a feel 
for what it is like to push the electric.


My suggestion. By solar. Put the mower in a locked area, garage for 
example. Mount the solar panel on the roof, and run a wire to charge it. 
Don't forget fuses in BOTH electric lines.
