I think the first thing to do is get him to move one scoopful to a nearby location, and get him to do it several times. Maybe some sort of applause or reward for a small pile. That should show him that actually he CAN DO IT just one small piece at the time. After that, turn him loose and let him play.
Put a dollar in a fund with each scoopfull and by the time he gets it moved, you will have enough to pay for his new tractor.
Great picture!!!
