Any idea what this hole in the floor behind the seat box would be for? I know the one to the left of it with the bolt in it mounts the cab. However, I am not sure about this other one. Is it also a cab mount or does anyone know what it's for. There is also one on the driver's side exactly the same. See picture below. Any ideas? As always, thanks fellow StoveBolters!
