John Deere 70 Mower Blade FAQ
Can you modify a John Deere 70 blade center hole to fit?
Do not do that. The captured center-hole detail is 0.69 in (17 mm). Grinding or drilling a mower blade can ruin balance and create vibration
Should you buy one John Deere 70 blade or a full set?
The single blade number captured is M143202, and the set number captured is GY20567. 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
Which blade type should you use on the John Deere 70?
The blade type captured is high-lift, mulching, standard, bagging, and 3-in-1. Use that against the captured fitment value M143202. 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.
