Update: the electric mower works well, cuts better than my old gas mower, and the drive option works very well. Since the batteries make it heavier than a gas mower, the power drive makes a big difference. Hacking through very long grass, the batteries last about half an hour, keeping previously cut grass trimmed short I think it would last a lot longer. Its enough for me]
Actually, what really happened was that I tried to mow the grass last weekend and decided that my old gas lawnmower wasn't up to the job, so I did some research and bought an electric one. Its quiet, doesn't need gas, the throttle and air intake don't need cleaning out and just starts when I want it to.
I ordered it from Amazon.com on Sunday evening, as usual, with the free 5-7 day shipping option, and it arrived on Tuesday. I guess Amazon had nothing better to do than ship stuff... but it was nice to save $67 for shipping a 100 lb package and still get it very fast.
I got the latest biggest electric I could find, the Epic EP21H 24Volt cordless self propelled 21 inch. The rear wheels are belt driven from the main motor via a gearbox. It has a high efficiency brushless motor that drives the blade directly and two 12V lead acid batteries and should run for 40-50 minutes per charge. This is plenty of time for me to get fed up with mowing and charge it overnight. Its a bit bigger and more rugged than my old 4HP 20inch gas mower, and has a side discharge option so won't get clogged trying to mulch tall grass. I'll try it out after work.
I've also been looking forward to getting solar power installed on my roof, and I'm finalizing plans to make a commitment to get it done this year. I will blog my way through the process as it happens...
