Perfect for greenskeepers, professional landscapers and athletic field maintenance, Bush Hog pluggers aereate, dethatch and improve water intake. The ¾-inch spoons provide excellent soil penetration, allowing nutrients and air to reach the turf’s root system to promote healthy growth. A 1 ¼-inch diameter shaft with greasable sleeves supports independent hubs. The steel frame is designed as a weight box so weight may be added to increase down pressure for heavily compacted soil. Slicing knives are also available on all models. - Less
