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
