Riding Mower - Blades would not turn- washer spindle was jammed
Alfred - September 21, 2016

Tools Used
Screwdriver, Pliers, Socket set, Wrench Set, Adjustable Wrench, Air Compressor & pneumate wrench
Had to go through the steps to remove mower deck in order to get to the blade assemblies. I had not lubricated the spindles since I started using the mower so the spindle washer had disintegrated which caused the blades to jam. While I had the mower deck removed, I went ahead and replaced the blades, spindle blade washers and the retaining nuts. I also lubricated all the points which I had previously neglected and performed the mower deck height adjustments. I am happy with the results.

I parked my riding mower on ramps to make access easier to the nut which secured the blade. After removing the blade i removed the broken washer spindle, applied grease to the threads, installed the new washer spindle and new blade. The most difficult part was getting the nut securing the blade loosen.
