somewhat frustrating
The mower blade spindle is the same as the old part, with one exception. The holes for the sae bolts were not threaded. Which I did not discover until I put my glasses on to see why the bolts would not thread in. Would have saved me some time and frustration, had I known.

1. Removed blade.
2. Relpaced old spindle assembly with new by removing and installing four mount bolts. New housing bolt holes were self threading and took some effort to run up, but went. Now secure.
3. Made sure belt was on pulley properly and working.
4. Sharpened original blade and reinstalled.
Everything worked great with even grass cut.
