What a difference!
Could not find a replacement blade locally for my very old John Deere 14PZ. Blade was >10 yrs old, re-sharpened each year, but had lost its curled wing tips. Ordered and very quickly received the M77178: it fit perfectly, mulches and cuts as well as when the lawnmower was new!

Blade is great. Exactly what I wanted. Only down side is it took to long ship and I had to contact green parts for a tracking number. First time that happened and hope it doesn't happen again..

Mower Blade
Fits mower perfectly, looks like original, well sharpened. Blade too important to risk sacrificing quality/safety with off brand, so glad to get John Deere replacement.

Good product
I emailed your store on a weekend and received a quick reply. I have never mulched with my 13 year old mower, and finally bought a standard blade. The new blade works great for bagging! Thanks for the good advice.
