Kubota T1670 Belt Size FAQ
What should you watch when fitting a 68 in (1,727 mm) deck belt on the Kubota T1670?
A 68 in (1,727 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
Can you replace the Kubota T1670 belt with the same length but different width?
The drive belt width found is 0.5 in (13 mm). That is the common 1/2-inch belt width range. Still match the OEM number because the belt angle, fabric wrap and effective length can differ. A belt with the wrong top width can ride too high or too low in the pulley even if the length looks right
Which Kubota T1670 belt needs more careful length matching?
The drive belt is longer here: deck 68 in (1,727 mm) versus drive 69 in (1,753 mm), about 1 in (25 mm) different. Do not cross-match them just because both are mower belts
Why does the Kubota T1670 deck size matter before buying a belt?
The deck size captured is 42 in deck. That matters because the same tractor model can use different belt routing on different decks. Match the 42 in deck deck before relying on 68 in (1,727 mm)
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.
