Kubota T1870 Belt Size FAQ
What should you watch when fitting a 69 in (1,753 mm) deck belt on the Kubota T1870?
A 69 in (1,753 mm) deck belt leaves little room for sloppy routing. This is a mid-length belt run, so routing and idler position still matter more than just matching a close-looking belt. Before blaming the new belt, compare the belt path to the routing decal and make sure it sits on the correct side of each keeper
Should you buy the Kubota T1870 belt by length only?
No. The deck belt width found is 0.62 in (16 mm). That is wider than many light mower belts, so do not replace it with a thinner belt just because the length is close. It may sit too low in the pulley and slip. Use length, width and OEM part number together where possible
What is the fastest way to confirm the Kubota T1870 deck belt?
Start with the captured 42 in deck deck and the deck belt value 69 in (1,753 mm). Then check the belt routing decal or parts diagram so you do not order a belt for the wrong deck
What is the risk with the Kubota T1870 drive belt part number?
The captured drive belt number is K5112-71420. If the length and width are missing, a cheap cross-reference can still be wrong even when it claims to replace the OEM belt
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.
