摘要：
A turf aerator is disclosed which is configured with components that allow a user to set a desired turf aeration depth and then automatically adjust hydraulic pressure to produce a proper level of downward pressure into the ground in order to maintain consistent depth penetration with the tines. The turf aerator implements a depth control lever that is operatively connected to a switch that increases or decreases tine depth up or down. Since the desired tine depth is set and the hydraulic pressure is capable of puncturing the ground accordingly, portions of the ground that are relatively harder or softer are still properly penetrated due to the set level of depth. The turf aerator is also configured with a tine housing which shields drive chains from dirt and debris from the aerating, thereby increasing the life of the drive chains.
