Description

New steering shaft suitable for a wide range of Kubota B-series tractors. This shaft transfers the movement of the steering wheel to the steering box and the tie rod ends. The worm gear at the end engages with the gear in the steering mechanism, ensuring your tractor steers tightly and without play again.

⚠️ Check the chassis number — there are multiple versions!
