Also, setting the park break farthest switch on right. Bright red. Will let you exit with it running. If not, that is another issue. Potentially seat or seat belt sensors. Watch the icons on the panel when you get out. Does the seat light go out? Does the seat belt light go out when connected?
Everything has to work in sequence. Bad grounds, faulty sensors and bad selonoids plagued me for the first year. Download an operators manual and study a parts list and you can work through most issues. A good multimeter will be your best friend. This forum is full of helpful people.
The machine is a beast. No def or emissions to deal with. Keep the fluids changed religiously, especially the final drives, and it will last. Mine is the most used piece of equipment on the farm.
