Middlesex County, Ontario | I've used a mechanical murphy switch with a clearance marker for a similar purpose.
Murphy switch, you can adjust the pressure at which it switches with a small allen key: https://www.fwmurphy.com/products/gages/20p-25p-series
Generic 3/4" clearance marker that doesn't look too out of place on a dash and mounts very nicely in a drilled hole: https://www.amazon.com/Partsam-Marker-Clearance-Light-Brake/dp/B019B...
By using a murphy switch you can use it to switch whatever you want. Add a buzzer if you want, or cut the fuel supply (will need an override button to start the tractor). |
Oil pressure gauge with Incorporated idiot light?
