This is expanding on what Bob said, but the more hydraulic oil your tractor is pumping, the more fuel you're burning. Any time you run your tractor, you're wasting fuel if it just sits there, as the hydraulic pumps are pumping, but only oil circulation is being accomplished. When using the tractor, if the only hydraulics you're using is power steering, then there is still a waste of used power as the pump is still in full operation. Engine powers the pump, pump charges the lines, relief valves return oil to the reservoir.
I used to have a Pasquali 986 tractor (little Italian job) that had no power steering or brakes - only the 3-pt lift for hydraulics. It was a 21hp, 1-cylinder diesel and had about a 2-gal fuel tank. I once went about 2 days of using a 5' brush hog to mulch up a lot of downed tree limbs that were piled up. Didn't need to have the engine RPM's up high, so was slightly above idle. About 2 good days of running on 1 tank of fuel!! (a little over 8 hours total, if I remember correctly)
Many modern tractors are all-hydraulic. So, all the time that they are running, they are working at the full capacity of the engine RPM's. Not very efficient, but very easy to operate and simplified engineering.

He got this wild idea that we should get a convoy of AC tractors and drive them from Charlotte, Michigan 105 miles to LaGrange, Indiana.
