While it's specifically for the independent hydraulic lift switch for the mid mount mower deck (which is what I use it for), you could really install any type of switch in the location. When I get around to mounting my LED lights to the ROPS, I'll most likely install the light switch next to (or under) the lift switch. If I recall, there's plenty of room behind the panel. I'll probably go so far as to install two switches under the lift switch; one for the ROPS lights and one for the rear lights.
I put an electric linear actuator on the chute angle adjustment which determines throwing distance. The switch for it went into that opening. It's nice to adjust the throwing distance from the seat of the tractor. I didn't like the mechanical option for that adjustment.
