Hi Silver Fox,
As a general rule of thumb any decent Scarifier will also Aerate to a
certain
extent depending on how well it is manufactured. The old
Qualcast and Black &
Decker models used to use "spring tine" scarifiers
which worked only as a
scarifier and not very well in my opinion.
Modern Scarifiers normally use a
primary drive spinle which has several
blades mounted vertically to not only
remove the moss and thatch but
also to cut in to the sod and improve aeration
and gradually reduce the
problem year on year (distribute sharp sand or similar
after using the
machine)
Some good brands in the electric stable (which also have good after
sales
service for spare parts etc) MTD Lawnflite, Al-ko and
Mountfield.
You will often find collection bags are sold as an optional extra for
these type
of machines. Scarifiers are not very good collectors and I
would always
recommend using a Rotary Lawnmower after the scarifier
purely to collect the
debris. They work on vacuum and will effectivly
hoover up anything left lying
loose in the lawn.
Hope this helps
