![]() Given the spacing of tines on many aerator machines this means several passes could be necessary. It is recommend to space aerator holes 3 inches or less apart. Warm-season grasses (Bermudagrass, buffalograss, zoysiagrass) should be aerated in May through July. Cool-season grasses (bluegrass, fescue and ryegrass) should be aerated in early spring or fall (March, April or September). Grass type determines the best time of year for aeration. However, a well-made manual aerator offers advantages such as ease of use, selective aeration, and economy. Some products also have issues with the tines becoming clogged with soil, which can slow down the operation even more. For a typical residential lawn (1/4 acre lot), it will take hours to finish. Manual aerators are much cheaper than powered ones. By repeating the same operation, the cores left in the tines will be pushed out by the next ones. Then he pulls the handle on the step bar upward to remove the soil cores out of the ground. ![]() The operator puts one foot on the step bar and push it downward, forcing the tines to penetrate into the soil. Manual aerators usually have two to five hollow tines mounted on a step bar. The machines can aerate a large lawn in a relatively short time (similar to mowing speed). The big advantage to a spike aerator is supposed to be that is doesnt leave those cores all over the grass. Powered aerators employ the power from ground propulsion to drive multiple tines into ground. manual aerator Powered core aerator in use Core aeration is suitable for heavy clay soils, and spike aeration is more suited to sandy or loamy soils. This reduces compaction in the soil, and the holes can stay open for a long time allowing air, fertilisers, and water to reach the roots. A core/plug aerator removes soil from the ground and leaves the core on the turf. Since there is no soil removed from the ground, watering will cause the compacted soil around the holes to expand and close. core aerators have hollow tines that pull out plugs (or "cores") from soilĪ spike aerator creates holes in the ground by pushing the soil sideways as wedge-shaped spikes penetrate the soil.spike aerators use wedge shaped solid spikes to punch holes in the soil.Soil compaction makes it difficult for grass to develop long roots and disturbs both natural rainwater and artificial irrigation. Lawn thatch is a layer of dead organic tissue that can protect the lawn by moderating temperature and reducing evapotranspiration when it is a reasonable thickness, but too much thatch can limit soil oxygenation and reduce watering effectiveness. Severing the roots causes them to multiply and thus the blades of grass multiply, keeping the lawn thick and deeply rooted as the holes become engorged with roots. Aerating either by coring or spiking causes the roots to divide or sever apart, which rarely happens naturally. Lawn aeration involves controlling lawn thatch and reducing soil compaction, making grass roots multiply. In compacted lawns, aeration improves soil drainage and encourages worms, microfauna and microflora which require oxygen. Lawn machine Core lawn aerator attachment on a conventional front-tine garden tillerĪ lawn aerator is a garden tool designed to create holes in the soil in order to help lawn grasses grow.
