Title:
BELT,V – SINGLE BELT (KU-6609125090)
Description:
The KU-6609125090 single V-belt delivers dependable engine-to-deck power transfer, ensuring smooth PTO engagement and consistent mower performance. Designed as a primary drive belt, it actively transfers power from the engine to the deck system—so your blades operate efficiently and maintain a clean, even cut.
Kubota engineers this belt with a wrapped V-profile that enhances grip within pulley systems while supporting smooth clutch engagement. Its reinforced aramid (Kevlar-style) cords resist stretching and absorb shock loads, allowing the belt to maintain correct tension under varying operating conditions. As a result, you reduce slippage, improve efficiency, and protect critical drivetrain components.
In addition, the belt’s durable outer fabric minimises wear during repeated engagement and disengagement cycles. This design ensures quieter operation, improved heat resistance, and longer service life—even in demanding mowing environments. Consequently, you benefit from reliable performance and reduced maintenance frequency.
Because it meets OEM specifications, you can install it quickly and accurately. Ultimately, this belt restores full PTO functionality and keeps your Kubota mower running smoothly and efficiently.
