Different tines are available. Standard it is delivered with 11 mm / 0.43” outside diameter hollow tines. But also other hollow, solid, cross and needle tines are available.
The maximum working depth is 50 mm = 2”. The depth is set via the turf hold down shoe plate at the PT 23. At 2,2 km/h groundspeed (standard groundspeed setting of the PT 60 base machine), we get a square hole pattern of 43 x 43 mm = 1,7 x 1,7 “.
The PT 23 Hollow Tine aerator is maintenance free. It weighs about 40 kg = 100 lbs.
A new application for the PT 23 Hollow tine corer is using it as an aerator at artificial turf, to crack the infill that is compacted due to the usage and/ or circumstances. If we mount the needle tines and set the depth at the correct value, the tines will enter the compacted infill and loosen the compacted layer.
