Shop for Outdoor Power Equipment at The Home Depot. Ideal for larger lawns, Brinly s super wide, high-performance 48 in. Tow-Behind Plug Aerator is the tool needed to keep your lawn lush and beautiful. This heavy-duty aerator features 32 heat-treated steel tines that penetrate the soil up to 3 in. depth. Each plugging spoon can be replaced individually, providing less expensive maintenance from having to replace the entire spoon shaft. Four separate welded tine sections rotate independently, even during tractor turns. And for those really compacted areas where maximum penetration is needed, an additional 200 lbs. of weight may be added to the fully enclosed steel tray. Need to cross the driveway or drive over a sidewalk. Simply use the single lever to engage the semi-pneumatic transport wheels.
