Find the Fuel-Saving Slot

Slot DozingCaterpillar claims that any bulldozer making a cut that's a foot deep or more can improve its productivity as much as 20 percent by slot dozing. The operator simply repeats passes in a single blade width, cutting a slot to grade. Then moves over to repeat the process and create an adjacent slot. As each slot deepens, the sides hold material on the blade. Each cut moves more dirt than the last. Best of all, annual fuel costs for a 165-hp tractor that burns 5 gallons of fuel per hour in production dozing drop about $1,000, if fuel costs $1.10 per gallon.
