As tractor and other engines get more sophisticated, the cleanliness of the fuel in your farm tanks becomes more important.

For those who have a problem with diesel cleanliness, Agriemach has a possible solution – its diesel purifying system. This can suck the diesel out of a tank in situ, filter out the water, dirt, sludge, rust and bacteria and put it back in again.
