The JRCO Tow-Behind Hooker Plug-Style Lawn Aerator with Electric Actuator and 61in. working width has tines that pierce deep into the soil, hooking and lifting loose plugs of dirt, spreading nutrients that disperse over the surface. Use it in combination with over-seeding for renovating distressed or diseased turf. Produced holes are approximately 1/2in. wide x 1 1/4in. long and up to 3in. deep. The soil volume removed is comparable with a 5/8in. hollow tine core. Soft-plug style aeration is ideal for golf fairways, sports fields or anywhere true plug aeration is needed, without the messy compacted core clean-up of a hollow tine aerator. Designed to get the job done much faster than traditional hollow tine aerators, with few moving parts and no engine for very low maintenance.
