FWIW, my last post was 10-28-13.
Bought a second 20" Twin Blade last November on a trip from WI to MS. Hard to find them in ANY Lowes stores back then. Used this second one for two grass cuttings and, when cleaning bottom side yesterday, noticed a 4-5" long crack in deck underside starting from the perimeter of the left hand motor base and extending upward to center of deck. My phone call to Greenworks seemed to be handled well, especially for a Saturday afternoon. Gave me the number of a local service center (THAT surprised me in our town of 20,000) and said I could bring it there (with proof of purchase) or they would send me a new deck. Not wanting to do all that extra work right now, I'll be bringing it to the service center. My only concern is that I can't find anyone who's ever done business with this outfit and the 2 reviews I found online don't look optimistic as far as their quality of service. We'll keep you posted on the outcome of this warranty service. Date of manufacture is 12/2012 -- 5 months earlier than the mower I bought three months before!
On my #1 Twin Blade (manufactured 5/2013), I noticed a thumb sized part of the deck that had broken nearly off on the rear, lower edge of the deck underside. You'll notice this area has some thinner construction than much of the rest of the edge perimeter. I'm going to try to rivet on some strap metal backing to brace this piece so that it stays on and doesn't break off completely. It likely caught one of our protruding roots when wifey was mowing last year. I can't see the blades generating enough force to through a rock through the area hard enough to break that piece the way it's situated.
Still not thrilled with the battery life but with two chargers now, and the 4 batteries that come with 2 mowers, I think we'll be OK. All 4 batteries fully charged were not enough to mow our 1/3 acre a few weeks ago but some of the grass was pretty tall and required the higher speed engine function when mowing. Next time I'll start with the smaller batteries, put them on the chargers as soon as they're discharged, and see if they'll be charged up enough to finish off the whole job without having to split the lawn mowing into two days. The gas mower (22") would usually allow us to mow the entire lawn in 90+ minutes. We've got 2 ditches, lots of trees/stumps/flower beds, etc., to mow around. Most of the area has a 50/50 forbs/grass coverage. (Some would call that weeds/grass!). Lots of shaded areas makes the lawn fairly thin in about 30% of the yard.
Back to work ....
