John Deere X380 Mower Blade FAQ
Can you modify a John Deere X380 blade center hole to fit?
Do not do that. The captured center-hole detail is round / 0.81 in (21 mm). Grinding or drilling a mower blade can ruin balance and create vibration

The captured single blade number is M144202, while the captured blade set number is M145476. Use the single blade number for one replacement and the set number when replacing the full deck set
Which blade type should you use on the John Deere X380?
The blade type captured is high-lift, mulching, bagging, and 3-in-1. Use that against the captured fitment value M144202. High-lift helps bagging/discharge; mulching blades need the right mulching setup
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.
