    i was thinking about tig welding a set of doubles together, the only negative i could think of is if i hit an obstacle like a root or pipe.

    Any other opinions?

    Pro’s – they would not move, it would be faster to put on your mower.

    Con’s – if you trashed one blade you lost two, I think it would take longer to balance the welded doubles than the singles.

    Weld up a set and see how you like them.

    The only time I have ever had doubles to move on me , is when I hit a solid object (which is good). I use a speed square and impact them on, and it would be much easier to sharpen and balance.

    Another thing is I was once told that welding mower blades will damage the temper on them which weakens them a bit so it's dangerous?
    I have welded doubles together once for a 21" mower. worked fine. I also once tried to weld some lift wings to gator blades. the lift idea didn't work (used angle iron, too steep of an angle LOL) but the welds worked just fine.

    Remember if you do weld them to do little tacks of weld at a time. Do not run the entire bead. This will cause your blades to warp from the heat.

    If you weld have good insurance as you are asking for trouble.

    why bother. my doubles take about 2 extra seconds to put on. put them both on the bolt, line that bad boy up, hand start it, then crank away.

    welded would suck come sharpening time.

    getting the perfect 90 deg isn't that important either. 80and 100 or 90 and 90, just so long as it is close gets you what you want.

    I would never in my life consider welding doubles together...how much time are you gonna save and how much more time is it going to take you to figure out how you are going to sharpen them?

    What happens if you bend the lower one?

    On my 60" mower, I run the stock 21"s on the bottom and 16"s on top
