I have a 2019 BX2680 with the dealer installed Curtis cab. I use it for snow removal and some tilling. This winter season the heat developed a coolant leak in the cab. In the process of trying to find the leak I decided to remove the inner heater shroud. This is located below the windshield. I searched to find how to remove this on the internet and called the dealer and Curtiss cab. No such luck on how to get apart. Had to figure it out. Access to the heater cores (there are 2 of them) and the plumbing to go with them removal of the inner plastic cover is necessary. This is accomplished by removing the fan grills with 4 screws each, 4 screws below the windshield inside the cab and 4 screw below the windshield on the outside of the cab. Once these fasteners are removed and the control knob is removed the cover comes off easily. As it turns out the hose clamps on the heater hoses needed some retightening. Only 12 hose clamps in this area. Curtiss used hose clamps that I needed to get a metric socket to tighten. Different than any I have run across before. It did sound as though this was a common issue with this cab in talking to the service man at the dealer.
