establishment of turf. Cores for propagation must be used when fresh,
shortly after coring is performed.
Solid tines are sometimes used in place of hollow tines and can be
mounted on the same machines. The solid tines penetrate the soil and
open holes, but no soil plugs are removed. The solid tines are less
disruptive to the turf surface, and recovery is faster, but they are
less effective in loosening the soil and relieving compaction.
