I'm just a beginner, but the basic idea is to use weight to sink the crankbait to the desired depth rather than letting out a lot of line as is done when pulling. The speed range is around 1.8 mph in order to get the right action from the lures. Most posts I've read on the subject recommend Bandit 300 series or Arkie 350 series crankbaits. If you do a search on pushing cranks you will get lots of good info.
