Kubota T1670 Mower Blade FAQ
Can you modify a Kubota T1670 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 T1670 blade or a full set?
The single blade number captured is K5677-34340, and the set number captured is 77700-05581. 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 Kubota T1670 blade kit?
Start with the captured deck setup: 42 in deck and 2 blades. Then confirm the blade part number against the deck tag, old blade stamp or parts diagram
Can you swap Kubota T1670 blade types?
The blade type captured is high-lift and bagging. You can often choose a different style only if it fits the same deck and spindle setup. Use 42 in deck as the fitment starting point
