John Deere GT275 Mower Blade FAQ
Can you modify a John Deere GT275 blade center hole to fit?
Do not do that. The captured center-hole detail is 0.62 in (16 mm). Grinding or drilling a mower blade can ruin balance and create vibration
What is the difference between the John Deere GT275 blade number and blade set number?
The captured single blade number is AM141039, 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 GT275?
The blade type captured is high-lift and mulching. Use that against the captured fitment value AM141039. 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.
