John Deere Z720A Mower Blade FAQ
Why does the John Deere Z720A blade center hole matter?
The captured center-hole detail is round / 1 in (25 mm). If the hole shape or size is wrong, the blade may not seat correctly on the spindle even if the length looks right
Should you buy one John Deere Z720A blade or a full set?
The single blade number captured is M154202, and the set number captured is TCU21475, UC22010, and GY20679. 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 Z720A?
The blade type captured is high-lift and mulching. Use that against the captured fitment value M154202. High-lift helps bagging/discharge; mulching blades need the right mulching setup
