Not so.Hollow tining removes cores to remove compaction allowing compacted
soil to take up its space and release carbon dioxide. Hollow tining should
be done every three years whereas solid tining every year,thats why hollow
tine aerators are used, ask any greenkeeper.topenworld.com wrote in message

Does anyone elese have problems with their hollow tine aerator. I
have one
with tines 4" long that become clogged at about 1" from the sharp
end. The
cores dont move up the tines and fall out the top. Is it a problem
with the
aerator or the types of soil I have got,and is there a solution

Why does it matter if the tines are clogged? The aerating holes are
made whether or not the tines are open. As a matter of fact, why are
the tines made hollow at all, except to make the implement cost more?
