John Deere R70 Mower Blade FAQ
Should you buy one John Deere R70 blade or a full set?
The single blade number captured is M144202, and the set number captured is 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

The blade type captured is high-lift and mulching. Use that against the captured fitment value M144202. High-lift helps bagging/discharge; mulching blades need the right mulching setup
Is the captured John Deere R70 blade part number enough to buy from?
