This will help on pulling cranks.
Pulling refers to putting the rods on the side or back of the boat , letting out a measured amount of line this causes the baits to run at a certain depth at a certain speed while the boat goes forward " pulling " the baits along behind it. With jigs its also called " long lineing ".

Pushing refers to haveing the poles on the front of the boat while boat is going forward , with jigs, its also called slow trolling ( depending on speed ) . With crankbaits its called pushing cranks.

Hope that helps alittle
