John Deere RX63 Mower Blade FAQ
Why does the John Deere RX63 blade center hole matter?
The captured center-hole detail is 0.81 in (21 mm). If the hole shape or size is wrong, the blade may not seat correctly on the spindle even if the length looks right
Should you buy one John Deere RX63 blade or a full set?
The single blade number captured is M89455, and the set number captured is M168223. 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
