Re: (ET) Electric push mower project

[Jim Coate <jbc coate org>]

I think the Etek is 15 HP *peak*, not continuos. And although I don't 
know all the other models listed I suspect some may be using continuos 
rather than peak ratings so not a fair comparison. For instance, the "10 
HP motor" (http://www.3rivers.net/~cmac/m1.htm) is 11" in diameter and 
80 pounds in weight. That is a much larger motor (generator) than the Etek!

Too bad they didn't keep things simple and just record the current draw 
for each type of blade rather than fancy pressure tests. I'm curious 
what brand the lowest pressure blade is and how much actual difference 
it made in power required. Oh well.
