Weed Pullers are made by different manufacturers such as Weed-Eater, Weed Puller, etc.  These tools are designed for different purposes, and they are very effective for removing different kinds of weeds.
There are various types of weed pullers, and it depends on the type of weed you are trying to remove.  If you need to remove smaller weeds, then you should use a small weed puller.  For larger weeds, you should use a larger weed puller.
You should also take care of the size of your weed puller.  A larger weed puller will be more powerful, and it will pull up more weeds.  But, if you are using a small weed puller, it will not be able to pull up as much weeds.  So, you need to choose the right size for your specific purpose.
