ABSTRACT:
An apparatus for aerating turf including a mounting frame (11) for mounting the apparatus to the hydraulic lift system (12) of a utility tractor. A trailer support frame (13) is pivotably mounted to the mounting frame (11) so as to enable the trailer support frame (13) to tilt toward and away from engagement with the turf. A plurality of rotary hoes (39) are supported within the trailer support frame (13) along a drive shaft (41). The drive shaft (41) is rotated by the power take-off (44) of the tractor, and causes the rotary hoes (39) to vibrate as the tines (58) of the rotary hoes (39) penetrate the soil so as to aerate the turf without causing compaction of the soil.
