Plow, crane, vacuum, gravity gun?

How should the player interact with zombie piles:

1. I think the plow is out.
2. The crane could work, but it seems awkward.
3. I was thinking it would be easy to go with the Kirby style. When a body is vacuumed up it would be instantly shot out of a positionable tube.
4. Rip off the gravity gun idea from Half-Life. It would also create interesting game play to not allow the carriage to move the zombies which would force the main character to get out of the carriage and use the gravity gun. Or the carriage could have a gravity gun attached to it.
