Product Description

?

This is a genuine OEM sourced replacement part used on Snapper and Murray lawn mowers. Mulching blades are designed to circulate the grass longer so it can be cut into smaller pieces. This makes your grass clippings better as mulch since the smaller clippings will decompose more quickly, releasing their nutrients into the soil. This part is made out of metal and it is sold individually.

Riding Mower - Blades would not turn- washer spindle was jammed

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 retai ning 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.
