Hello, I have a older 94 Kubota L-4350 which has been a great machine.I am at 10,000 feet in the Colorado Mountains which has extreme winter weather,winds and temperatures. I have a 3 point rear snowblower which adds to the conditions.HELP, I need hard cab that I can install heat in.The local dealers cannot locate one due to age of machine.I prefer to keep my old friend which has been a fantastic trouble free machine but am starting to consider a new model with all the conforts.Does any body have any sources or ideas on locating a cab or a interchange cab model which will work?
