I'm just glad to see anything made is USA. I wouldn't mind trying out one of the tri-blades. I wish them luck.

It is kinda like the 5 blade razor that works great.
Honda has a deal like that, seen it in ads.

I have a question mark of how effective they would be. I've reduced my lawn to about nothing, otherwise I'd try one. I also look at the hub section of the blade and think it doesn't look like a lot of metal there for the bulk of the blade.

Anyone think they might work on dandelions? My blades can be almost razor sharp and it still misses a few dandelion stems.

I saw an old walk-behind mower setting out for the G-man, so i asked the owner if he was tossing it out. He said he was. I asked why. He said he had the blade sharpened at a shop, but they didn't do it right, so he figured he'd might as well buy a new mower. Said it never cut very good.
Well, i took it home, turned it on its side, found the blade was installed up-side down! O-o-okay. Haven't fixed that goof-up yet, been busy with tractor belts, etc.

Well, i turned the blade over, installed some new gas, hit the bulb about 6 times, pulled the rope---and it started right up! Only trouble--it sounds like a big bag of rocks being tossed out on a steel drum! Right now, it is setting out front with my mower sign propped up on it. Maybe somebody will swipe it after dark! ;o)
