    I'm going to start changing my own blades on my mower and I need to buy either one. I was wondering if you all think I should get a torque wrench or cordless impact wrench. Will I torque the bolt too much if I use an impact wrench. Also, I will have to use impact sockets, right? I don't have an air compressor either so thats why I was thinking cordless. I just learned they made cordless this morning searching around.

    Cordless; Get a good one; I prefer RIGID; "FREE" life time parts, service & batteries (be sure to register) Have the 24V hammer drill; Sawzaw; &circular saw too. It really puts out the power.

    Check the torgue specs before hammering home the bolts.


    You should really look into a compressor & an air tank & plug kit for you tires. I keep 25 glns air tank in my truck. Good for the trailer, ZTR & I can fill it with NitrusOxide the cheer up my crew after a long day :)

    You can also try Harbor Freight for low cost tools
  3. an impact gun, forget the torque wrench.

    A torque wrench is how it's supposed to be done. If you use an impact use it on the weakest setting it has and then check the torque with a borrowed torque wrench.

    +4 for a cordless impact - hand tools are painfully slow. I also use a dewalt 18v. Torque wrench is good to have anyhow but not for this.
