John Deere X166 Mower Blade FAQ
Is a close blade length good enough for the John Deere X166?
The blade length found is 28 in (711 mm). Close is not the same as correct. That is a large-deck blade length range. Do not guess here; wrong blades can hit baffles, leave strips or overload the spindle. Match the OEM number or old blade before buying
Should you buy one John Deere X166 blade or a full set?
The single blade number captured is M154202, and the set number captured is GY20683 and GY20684. 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
Can you swap John Deere X166 blade types?
The blade type captured is high-lift, mulching, standard, and bagging. You can often choose a different style only if it fits the same deck and spindle setup. Use 28 in (711 mm) as the fitment starting point
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.
