    I am thinking about purchasing an electric impact wrench to assist in the removal of mower blades. I don't have the room for a large air compressor and would like something more portable. Do these electric units (Dewalt, Makita, Sears, Etc.) produce enough torque to remove tightly fitted mower blades? I was looking at both cordless/corded options? Also do these impact wrenches cause any damage to the spindles or other parts? Any suggestions (brand, model, torque requirement) would be helpful. Thanks.

    Do a search on this site for 'impact or 'impact wrench'. I think it was this site that had a thread where someone bought a cordless one from Home Depot or Lowes and he liked it.

    I bought one from Harbor Freight and I thank it was $50 bucks. Use it every day and it works really well. I wish I would have bought this tool before any other.

    I have a DeWalt corded wrench and wouldn't think of changing blades without it, although the guys in my dealer's shop use a cordless one and say they would rather use it than the compressed model they have. I don't remember the brand of cordless they are using, sorry.

    Bought my electric one at Harbor Freight also. $50 on sale. Crazy thing has the trigger reversed so to tighten I have to put the switch in "reverse". (Made in China and they obviously couldn't read English) But it works great and I couldn't break the blades loose, even with a cheater bar, until I got the wrench.

    Mine is more powerful than the impact and air compressor is. Its a no name cordless that i got off e-bay. I was pleasantly surprised with it. Well worth the money.

    I had a similar one from Harbor freight. It said made in China.

    Used it for 2 changes and the third one I had all the motor sitting outside the plastic housing in pieces. Buy good tools.

    $300 +/- Cost new including charger and 2 batteries.

    Blades, lugnuts, etc. no problem.

    Super time saver especially if you have multiple mowers and a tight schedule.

    We buy spare blades, and change them in the field. Running the ZTR up the trailer gate on one wheel lets you remove/install one outboad blade and the center, then switch sides and change the remaining blade.

    The cordless impact has been a huge time saver on the JD1600 WAM, with 7 blades.
