commonly , aeration is want only on older , compacted or heavily thatch lawn , but newer lawn may need to be aerated if they are growing on clay or are subject to heavy traffic . In recent years , manufacturers have been marketing aeration affixation that fit onto a cultivator ; these are designed to exchange heavy , expensive rolling lawn aerators .

Rolling Aerators

Traditional rolling lawn aerators are self - impel or they are pushed or pull by garden tractors . Self - move models are ordinarily heavier and so are more effective . Weight may often be added to extract - behind aerator . Many models are similar to lawn mowers and are designed to maneuver around obstacles and corner ; some models have power - ski lift so that the operator does not have to hook the rolling drums by hand ; still other models extend the wheeler dealer .

Rolling lawn aerator are usually gruelling , with weight unit sometimes gained by adding water to a drum . The intemperate weight unit of rolling aerator helps push tines profoundly into the filth and smooth the open of the lawn .

Tiller Aerator Attachments

aerator bond to the front of tillers often have expectant cast - iron rollers to improve the penetration of their tine and help groom the lawn , but they still ordinarily librate less than most rolling aerators . However , their maker say the same amount of weight unit is employ to each tine , and the tines are designed to penetrate equally inscrutable . While heavy rolling aerators may be expert for older lawn that are heavily pack together or have thickheaded layers of thatch , a tiller adherence may suffice for a newer lawn .

Cost Comparison

Having an aerator bond that match onto your tiller means that you do not have to buy a separate , usually more expensive roller aerator or hire a master to roll your lawn . Lawn aeration serving can be expensive , and since lawn are well aerated after at least 1 inch of rain , rolling aerator for split are often unavailable because of dense need .

Labor Comparison

Most rolling lawn aerators have 24 tines to remove spikes of soil from the lawn . Aerators that match on the front of tillers have fewer tines , so from two to four bye must be made over an expanse to get the same aeration benefit . Rolling lawn aerator are often very intemperate , and handling them requires strength and vigour . Aerator attachments broadly speaking require less strong-arm labor than heavier rolling aerators .

Tips

Some aerator have tine that pull ½-inch to ¾-inch cores of stain from the lawn ; others drive solid spindle into the terra firma without removing stain . Whether you have a rolled aerator or one that fits as an attachment onto a tiller , agronomists at the Virginia Cooperative Extension say that it should take away cores of dirt from your lawn and that aerator that merely drive capitulum into the lawn can increase grunge compaction .
