I think square tires on the digger would just bury up in the dirt as the digger is being pulled. The octagons or pentagons might work, but to get any real shaking action, your puller might have to travel faster than you want to work. Paddles on the digger wheels might give the traction to make the wheels turn and would also provide a bumping effect, but every time one of the paddles when into the ground, the digger would also be lifted up. A eccentric and pitman arm connected between the digger wheels and the sifter box would probably be the simplest and easiest method to get the shaking action needed if you puller doesnt have a pto
