I have a 2006 JD 2305 with a 54" mulching deck. I have been removing and installing the blades with a impact wrench for 11 years, no problem.


Yesterday, after sharpening the blades, I was hammering the bolts as usual and stripped them out. I guess after 11 years, they just couldn't take it anymore. I guess that's why the manual says to torque them down to 50 ft.lbs.


Well instead of spending $72.00 each for new spindles, I retapped each one with a 1/2 x 20 tap.


Worked out great and saved me some money.


Long story short, go easy on the impact wrench.

It's not hard to do with an impact. Glad you were able to repair instead of the expensive replacement. I use an impact to remove but tighten by hand. My blades don't need to 750lbs of torque my impact can deliver.

I use a battery impact.  No hose to drag around, tightens them tight enough to stay on.  Don't deliver near what an air impact will.  Be a good idea to change those bolts every couple years anyway.
