John Deere S180 Mower Blade FAQ
Can you modify a John Deere S180 blade center hole to fit?
Do not do that. The captured center-hole detail is 1 in (25 mm). Grinding or drilling a mower blade can ruin balance and create vibration
Should you buy one John Deere S180 blade or a full set?
The single blade number captured is UC20448, and the set number captured is GX22151 and GY20850. 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 S180 blade types?
The blade type captured is high-lift, mulching, bagging, and 3-in-1. You can often choose a different style only if it fits the same deck and spindle setup. Use UC20448 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.
