The monitor connects to the system wiring harness via a multi-contact connector. I could have hidden the connector below the cowling but decided to leave it exposed. This allows me the option of removing the monitor from the mounting bracket using the four thumb screws. I see myself doing this during the winter season when I've no use for the monitor. I can then store it in my basement and won't run the risk of damaging the LCD display. It is rated to -40F which is about as cold as it gets here on the homestead. Nonetheless, there is no need to risk it when I've no reason for it to be on the tractor during the winter.
As I write this, I'm currently experimenting with various camera mounting locations. The one shown here was made from a couple of pieces of scrap wood, some Gorilla glue, and a few screws. It has a tight friction fit into the draw bar hitch on the tractor.
Once fully inserted into the hitch, a bungee cord is used to keep the camera's mount in position. No wrenches or screwdrivers are needed to install or remove the camera and mount from the tractor.
The camera's power/video cable attaches to an extension cable that runs along the tractor's frame and connects to the system harness behind the instrument cluster. I used a couple of zip-ties to keep the camera cable away from the PTO shaft and other parts of the tractor where it could be caught on something and cut. I also used plastic wire loom covering on the camera cable and the extension cable to further protect them from spomething that might wear a hole in the cable sheath. The zip-ties allow for an easy reinstallation or removal of the camera and mount.
Having now used the drawbar mounted camera while grinding a half dozen stumps, I've found that it sits too low so I find myself looking across the stump rather than down on it. This causes me to lose my depth perception and makes it difficult to properly position the grinder at the back side of the stump. I have designed another mount that attaches to either of the front support legs of the stump grinder. This provides the camera with a downward viewing angle and should make it much easier to position the grinder at the back edge of the stump. I will provide a couple of photos and additional comments once I get a chance to try it on some stumps.
