    Is it really necessary to torque the blades when changing?

    I think he means use a torque wrench.

    And in that case, no, unless its a Walker or Exmark Navigator, that runs off the gear boxes or whatever, and in that case, it is very important to have them torqued right.

    Yes, torque (tighten) to certain specified foot pounds.

    No. I always tighten my blades firmly by hand with a 1/2" drive socket wrench. Two Hustlers and a Deere and never a problem.

    Very simple isn't it, run them up until the impact wrench hammers and move on. No problem to be found with this procedure, just a matter of feel.

    I would torque them if the bolt goes into threads in the spindle. This way you cut down on wear on the treads in the spindle. My scag has a long bolt that goes through the spindle to a nut on top of the spindle. I use impact on this to save time. Easy to replace a bolt and a nut if it wears out or breaks over time. Spindle shafts are no fun to replace.
