    Which is better for removing blades, The electric impact or torque wrench?
    The specs on my blades are 70lbs. and I can't find an impact wrench less than a min. of 100lbs.

    For removing it doesn't matter how powerful the impact wrench is (as long as it has at least the specified torque of your blade bolt) but I would never put a blade on with an impact.

    I'm guessing he meant "replacing" not that I think about it...

    A torque wrench is for torquing things down to a specified torque. They are not a removal tool. An impact gun can be used for removal. Get good enough and you can put em on with it too on the lowest setting. You'll get the feel of not going too tight.

    There's a product called Torque Sticks that are flexible and will limit how much torque you put on with your impact. They are used by tire dealers. However, I don't think they are available in a value low enough for blade bolts.

    I remove and replace blades on various brands of equipment daily with a simple socket wrench(14") handle. Never had a problem with them getting loose or with getting the blades off.

    On and Off with an impact for me. Much easier and dont have to fool with a torque wrench.

    Torque stix are a joke, very dependant on line air pressure and gun settings, they use them at tire stores, yes, and it's useless. My car's alloy wheels are notorius for distortions with uneven lug torque, resulting in brake rotor warp and vibration...they have to be torqued evenly at 100 ft/lbs...last time I had new tires put on, I watched them use Torque stix after I told them specifically to use a torque WRENCH on them....

    Got home and went over them with the torque wrench, they ranged from 60-120 ft/lbs...brake shimmy all the way home....

    I'm with you, I just have an old 1/2" drive ratchet I use, put a big block of wood in the blade's way and go to it...
