Use both. The deck size captured is 48 in deck, and the captured deck belt value is K3011-13560 and K3011-13561. Model name alone is risky when multiple deck sizes or serial ranges exist

Are the captured Kubota Z121S deck belt part numbers enough to buy from?

The captured deck belt numbers are K3011-13560 and K3011-13561. These numbers help with OEM lookup, but the deck belt length and width were not fully captured here. Before buying aftermarket, confirm the exact deck or serial range

Official information note

Mistakes do happen. Belt specs can change by year, mower deck, pulley layout, serial range and regional parts catalog. Please check the operator manual, belt routing decal, old belt label and official kubotausa.com before ordering a replacement belt.
