Try and remove those pulling it somehow, either by killing them or turning that immediate area unbearble to them (setting it on fire, etc) so that more don't come to their aid.
Best thing to do actually would be to dig a good moat around the castle and set up some ballistas in certain points. Once the tower gets moving, good luck trying to stop it.
Siege towers often had cattle hides hung from the sides like curtains to stop oil and arrows.

Catapults were usually brought to just about archer's range and parked there. The catapults covered the ground troops and siege towers while they moved in.
The Roman siege towers could be on rollers to be mobile or they could be stationary. They were built taller than the walls of the city they were attacking, enabling the men inside to fire down upon the enemy. Often a battering ram was concealed inside a siege tower. Because they were made of wood, the siege towers were vulnerable to fire if the enemy shot incendiary arrows them. The Romans had to be on the alert for this.
