The Bush Hog® Pluggers are literally designed to get to “the root of the problem.” The 3/4-inch spoons provide excellent soil penetration, allowing nutrients and air to reach the turf’s root system. A 1-1/4 inch diameter shaft with greasable sleeves supports the independent hubs. The frame is designed as a weight box so that additional weight may be added to increase down pressure when the soil is heavily compacted. All models are rated for tractors up to 60 PTO HP with a Category I three point hitch. Optional slicing knives are also available.
