John Deere S80 Mower Blade FAQ
Does 2.5 in (64 mm) blade width matter on the John Deere S80?
Yes. The blade width captured is 2.5 in (64 mm). That is a normal mower blade width range. Width affects airflow, lift and clipping movement under the deck. A different width can change airflow, cut quality and clipping discharge
Should you buy one John Deere S80 blade or a full set?
The single blade number captured is M170476, and the set number captured is M163983. If one blade is bent from damage, one may be fine; if they are worn down, replacing the full set usually gives a cleaner cut
Mistakes do happen. Blade specs can change by year, mower deck, spindle, serial range and regional parts catalog. Please check the operator manual, old blade stamp, deck tag and official John Deere parts catalog before ordering replacement blades.
