I have a bushhog brand. Works Good. Pay attention to what kind of shear pins the one's you consider to buy. One model of the bushhog PHD used custom shear pins at $9 each! Another model (mine) uses plain cheap 3/8" common soft bolts that you can pick up for less than $1 just about anywhere. Heavier is better, and hydraulic down pressure better yet. The lower cost ones are generally good enough unless you are fencing thousands and thousands of feet of fence.
