Here's the deal. If Grandpa wants to pull it with the loader your going to have to do something drastic before he can get to it. Get a buddy or two to help out. Take all the plugs out! Put more penetrating oil in each cylinder. Put the truck in 3rd gear. Rock the truck back and forth by hand several times. Bet it breaks loose. If not let it soak longer and try again by hand. As Jerry said no pulling with another vehicle until its already loose. You will bend or break something. If you have to, handcuff Grandpa to his recliner until you get the motor loose then let him "help" you get it fired up. Good luck.
