I don't know if it's possible to hook up a plow that is not made for the Kubota x1100c. Unless you are a mechanical engineer it will be hard to figure out how to mount a different make of plow.
Kubota makes its owner mounting system called the K connect system, it is made for melting snow blowers brush and plows. Is a very complex piece of engineering and it is very expensive. And some people have problems with the unit, I myself have never had a problem with my snow blower or the K connect. It is all hydraulics any mechanical drive shaft for the snowblower. All the controls for the unit is inside the vehicle on about a 5-ft cord with push button controls. And then you would have to buy a plow especially for this application. My guess is installed would cost you about $11,000. There's a couple of pics of the unit.
You also lose some ground clearance as you can see pic with the red arrow. You cannot take the unit off and on because it is very complicated setup.
I could be wrong and they could be something else you could use for a plow attachment but not that I know of. Hope this helps.
