Minecraft wiki entry for Snow_golems, associated text: Pulling turrets are like pushing turrets but with fewer golems, usually just one, and they have a hazard, usually lava, between the mobs and the golem. Instead of keeping the mobs away, their purpose is to bring them closer, where a trap awaits. It may take some time for the mob to reach the trap, as the knockback will slow them down, and this kind of turret usually only targets one mob at once, so it is advised to have several. If the trap protects the golem from all sides, such as a lava moat, they don't need as much protection, as no mobs will be able to reach them anyway. However, it is still recommended to keep them enclosed, to prevent them from moving and possibly falling into lava, and to protect them from skeleton arrows. Possible traps include lava, cacti, or even a pit. It can also lure monsters into a Mob Trap, where they are either killed, or weakened to be finished off by the player. This makes it a more versatile and strategic tool than a pushing turret.
