John Deere Z730M Mower Blade FAQ
Why does the John Deere Z730M blade center hole matter?
The captured center-hole detail is 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 Z730M blade or a full set?
The single blade number captured is M170476, and the set number captured is TCU21475. 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
How do you avoid buying the wrong John Deere Z730M blade kit?
Start with the captured deck setup: 60 in deck and 3 blades. Then confirm the blade part number against the deck tag, old blade stamp or parts diagram
Can you swap John Deere Z730M blade types?
The blade type captured is high-lift, mulching, and bagging. You can often choose a different style only if it fits the same deck and spindle setup. Use 60 in deck as the fitment starting point
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.
