Reviews

Perfect fit
April 24, 2021

Not sure what the updated part really means, but this was a perfect fit to the mower shaft. Had to clean up the keyway on the shaft a little as the edges were damaged over time by the old adapter. Otherwise a completely simple replacement.

Direct replacement, but not the same
September 03, 2018

The distance from the internal shoulder to the top is the same as original, but the blade now sits 1/4 inch higher than stock.
