Kubota Z125S Mower Blade FAQ
Why does the Kubota Z125S blade center hole matter?
The captured center-hole detail is 0.72 in (18 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 Kubota Z125S blade or a full set?
The single blade number captured is 77700-04210, and the set number captured is K5617-34330. 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

Start with the captured deck setup: 48 in deck and 3 blades. Then confirm the blade part number against the deck tag, old blade stamp or parts diagram
Can you swap Kubota Z125S 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 48 in deck as the fitment starting point
