Fits perfectly.

Fits perfect. Hate the plastic bolt though. This issue with the plastic bolt is that the edges round so had to use vice grips to take it off and put it back on. Would like a metal bolt replacement but cant find one.

OEM Quality

[This review was collected as part of a promotion.] I ended up getting my Greenworks mower from a neighbor that was moving away. I ordered a new blade after seeing that the one on it was pretty badly chipped up. This one was exactly like one i removed. Paint finished was great and the blade had a perfect edge on it. this thing cuts great. Zero complaints and price was fair.

Easy to replace and great

[This review was collected as part of a promotion.] The replacement blade is of exceptional quality. In contrast, my previous blade exhibited unusual behavior.
