The other day my guys told me I needed to sharpen the blades on one Zturn. So when I go to pull the blades the discharge side blade looks like a hockey stick...yeah, at least they noticed it was cutting bad! My AC impact wrench only goes 150 ft/lb torque so no hope there. I'd bent the long 1" openend wrench normally used on the spindle last bent blade, so I was down to either taking it to the mower shop and looking like a rookie or finding a way to break it out with a shorter 1" wrench I had....Problem was I couldn't lock in the 1" wrench on the spindle while I applied force with the breaker bar/cheater bar on the bolt (I was a tanker in the Army and our motto was "When in doubt, get a bigger hammer"). Solution: I took one of the 3 foot chains used to anchor my recovery winch; placed the hook on one end of the openend wrench on the spindle, wrapped the other end of the chain several times around a front-of-deck scalp wheel bracket and then padlocked it with one of the trimmer locks. NOW I was ready to "use the Force" on the cheater bar without worrying about the backing wrench slipping. Worked perfectly! I hope this helps someone when one of those new operators mangles a blade. (oh, btw, one of my customers is a steel coil plant, and I can't tell you how many pieces of miscellaneous metal truck drivers have tossed in the lawn that I have narrowly missed mowing over; so I can't really fault my operators - except for not telling me about it) Final odd comment for the day: How much paved road or driveway do truckers need around warehouses?..........Two feet more, always two feet more!
