Quality product by Har-Tru.
This 48" wide heavy-duty tow-model scarifier is truly a workhorse for loosening the top surface on Har-Tru courts. It is especially good for indoor courts and sun baked southern courts with excess calcium build-up. The unit is heavy enough to allow its two rows of case hardened nails to really penetrate the surface.
Check Out The Benefits:

Size - Sized to fit between alleys.
Levered Wheels - Levered wheels lift unit over tapes so tapes can be left in place.
