Kubota Z251KH Blade Notes
Blade note
The Kubota Z251KH blade listing captured here shows single blade part number K5617-34330, blade set part number K5583-34340, and thickness 0.25 in (6 mm). Do not buy purely from model name if the mower deck or serial range is different
Deck note
For the Kubota Z251KH, the captured deck information is deck size 54 in deck and blade count 3 blades. Deck size matters because the same model family can use different blade kits
Fitment note
Before ordering Kubota Z251KH blades, compare the old blade stamp, center-hole shape, blade length and deck size. Close-looking blades can still be wrong
Kubota Z251KH Mower Blade FAQ
Should you buy one Kubota Z251KH blade or a full set?
The single blade number captured is K5617-34330, 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
Why does the Kubota Z251KH deck size matter before buying blades?
The captured deck setup is 54 in deck with 3 blades. That matters because blade sets are deck-specific, not just tractor-model-specific
Is the captured Kubota Z251KH blade part number enough to buy from?
The captured blade part number is K5617-34330. That helps with OEM lookup, but the blade length, width and center hole were not fully captured here. Confirm the deck or old blade before trusting an aftermarket cross-reference
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.
