Kubota Z781 Mower Blade FAQ
Can you modify a Kubota Z781 blade center hole to fit?
Do not do that. The captured center-hole detail is 1 in (25 mm). Grinding or drilling a mower blade can ruin balance and create vibration
Should you buy one Kubota Z781 blade or a full set?
The single blade number captured is K5677-34340, and the set number captured is K5583-34340. 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
Official information note
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 kubotausa.com before ordering replacement blades.
