    Went out to change the blades on our 60" Lesco ZTR.

    First problem was that the spindle nuts were 1 1/8". Had to go to the store and get a socket that size.

    Next, I put my trusty electric impact wrench to hammering away. To my amazement, those nuts wouldn't bust loose. No problem---on to the air impact. Guess what? That wouldn't bust 'em loose either.

    What to do.

    What I did do was get a long breaker bar, and a 4' pipe cheater handle. The big probelm, of course, is how to hold the blades while you romp on the breaker/cheater bar. Nothing I tried in the way of jamming techniques had enough purchase to hold against the breaker/cheater bar.

    I ended up fetching a piece of chain. One end went around a front axle, the other around whichever blade I was on. This gave me the purchase I needed. Once the nuts budged, I was able to run 'em on off with the electric impact.

    Hope this helps someone.

    You shouldn't be putting them on so tight you can't get them off. For 3 years I always put blades on with an air impact, never had an issue.

    You're right about them being on too tight. However, that was done before I got into the picture. I really don't do much more than just snug up spindle nuts--because they tighten some with rotation.

    These things were like they were welded on, for some reason.

    Leverage, leverage leverage. I have been putting blades on for over 17 years, with only arm muscle. Never had a single problem, especially removing them...

    bump....

    rbig, I had the same problem with my toro 48", the first time I changed the blades was at the end of its first season:laugh: yeah I know, what the hell was I thinking -guess I liked the dull blade look.

    anyway, after doing much the same thing, I now sharpen every week, and use Fluid Film! No more problems.
