If you have forks check out Titan attachments. They make a grapple that uses fork pockets and goes on your forks.
About a half gallon an hour wouldn't surprise me for just tooling around doing loader work. You're probably only demanding a third or so of your horsepower potential. That'll change dramatically doing PTO applications that place a constant heavy load on the engine where the engine is producing almost all the HP it can develop. Something like running a bush hog in dense grass, turning a generator with a heavy load on it, or powering a hydraulic pump on a processor or anything else.
Something where you just get it up to speed though won't necessarily use a lot of power. These little Japanese motors like to spin; I like to operate both of mine at at least 1800 RPM, even just doing loader work. The hydraulics are faster for the loader and I think the hydrostatic transmission and the engine itself are happier if you're not lugging it down. Even with a bump in rpm the fuel economy doesn't change much. It really just depends on how much power you're actually demanding in my experience. For running my PTO splitter I run my little 29 HP New Holland at 2500-2600 RPM. Even with that much throttle it runs a LONG time on the tiny little tank. It'll split several cords of wood and plow the driveway a couple times on a tank.
I run 2 bale spears instead of forks on my old David Brown with a 4ft high guard to keep logs or whatever from falling back onto the tractor. I can unload logs off a hay rack with it and its great for shoving brush into a pile then picking up the whole pile in one shot. Picking logs off the ground doesn't result in huge divots.
