Somewhere under here is an engine ... After a hour of digging , I finally had the fan free of ice and snow .
Then it was a mission to fill the air tanks with compressed air for brakes and starting.
This truck never travels more than 3 km at a stretch !! but they still need the oil changing every year along with all filters and a good grease. The machines are not garaged , so are exposed to the elements every day of the year.
