Kubota mini excavators questions
Why one page for all these Kubotas?
They're small machines and most jobs are a pair of tracks or a few rollers. Send the model and we'll match it.
How do I find my rubber track size?
It's moulded on the inside of the track: width, pitch and link count. Send a photo of it, or the serial.
Can I put steel tracks on a KX057 or KX121?
Yes. We've quoted steel groups for both. 400 mm on the KX057-4, 350 mm on the KX121-3.
Do you have final drives for Kubota minis?
We've had KX91-3 requests. Send the serial and we'll check what's available.
