The 40-inch working width clears roughly an acre per hour at typical lawn-tractor speeds, with 32 hardened steel coring tines pulling true plug-style cores rather than the spike-style holes that simply compact soil sideways without relieving it.\u003c\/p\u003e\u003cp\u003eThe cores are roughly three inches deep, three-quarters of an inch in diameter, spaced at the density needed to genuinely break compaction in clay-heavy or root-bound lawns. Pulled cores deposit on the surface and break down into the lawn naturally over the following two to three weeks — no raking required, no debris to bag. The result is the same dramatic improvement in water absorption, fertilizer uptake, and root depth that golf courses pay landscape contractors to deliver, performed in roughly the time it takes to mow.\u003c\/p\u003e\u003cp\u003eThe frame is welded powder-coated steel with a concrete-block weight tray positioned over the tine assembly. Empty, the aerator weighs approximately 95 pounds — enough for shallow surface aeration on already-loose ground. Loaded with two standard concrete blocks (sold separately, available at any home improvement store for under $5), the unit drives the tines to full depth on packed clay or compacted high-traffic areas. The block tray loads from the top and requires no fasteners.\u003c\/p\u003e\u003cp\u003eTwo pneumatic 10-inch flat-free tires support the unit during transport between work areas. A foot-operated lever raises the tine assembly clear of the ground for turning, allowing the operator to mark coverage paths and avoid double-aerating overlapping passes — a meaningful efficiency improvement over fixed-tine designs that drag continuously.\u003c\/p\u003e\u003cp\u003eThe hitch is a universal pin design that accepts the standard rear hitch found on most lawn tractors, riding mowers, zero-turns, and ATVs. The aerator tracks predictably behind the tow vehicle without bouncing, even when fully loaded, thanks to a low center of gravity and a wheel base wide enough to resist sideways drift on slopes.\u003c\/p\u003e\u003cp\u003eFor best results, aerate when the soil is moist (the day after a soaking rain, or after a deep irrigation cycle) so the tines can penetrate to full depth without bouncing on dry ground. Most homeowners aerate once or twice per year — typically once in spring and once in early fall — with each session covering one to three acres in a single afternoon.\u003c\/p\u003e\u003cp\u003eThe aerator pairs naturally with overseeding (apply seed within a day or two of aerating to maximize germination) and with broadcast fertilizer application (the cored holes deliver fertilizer directly to the root zone instead of leaving it on the surface).\u003c\/p\u003e","brand":"Agri-fab","offers":[{"title":"Default Title","offer_id":42771593527390,"sku":null,"price":299.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1159\/9138\/files\/s-l960.png?v=1778943720","url":"https:\/\/sparroo.shop\/products\/40-tow-behind-plug-aerator-32-steel-cores","provider":"Sparroo","version":"1.0","type":"link"}
