Diesel tractors burn roughly 0.05-0.10 gal per horsepower per hour depending on load. A 40 HP tractor pulling a moldboard plow drinks about 4 gph; the same tractor mowing a lawn is under 2 gph.
Cost-per-acre matters more than cost-per-hour when you compare custom-hire rates. If a neighbor with a 90 HP tractor can disc your ground in a quarter the time, their higher gph may still be cheaper per acre.
gal/hr = HP × load_factor
gal/year = gal/hr × hours/day × days/year
$/acre = (gal/hr × $/gal) ÷ acres/hr
