摘要： A machine for cutting holes in golf course greens having a threaded drive shaft, a motor to rotate the drive shaft, a sod cutter at the bottom of the drive shaft and adapted to rotate with the drive shaft, a clutch that can be engaged and disengaged with the threads on the drive shaft, the clutch mounted on the upper end of an ejector cylinder concentrically encasing the drive shaft and adapted to effectively move downwardly when the clutch is engaged and to float free when the clutch is disengaged, supports for the plug ejector cylinder which allow the ejector cylinder to move along the axis of the drive shaft, and an ejector plate mounted at the bottom of the drive shaft and adapted to fit inside the cutter and to effectively move downwardly through the interior of the cutter when the clutch is engaged, in order to drive out the plug of turf and dirt inside the cutter.
