Device (30) for making a hole in a golf green (100), comprising a cutting cylinder (4) with an open end being freely movable along the longitudinal direction; guide means (1) defining a weight path having a first endpoint and a second endpoint; a weight (5) guidedly movable along said weight path; a weight propulsion device, arranged to propel the weight reciprocally so that it strikes against the cutting cylinder; and a soil expulsion piston (9), movable inside said cutting cylinder.

The invention is characterised in that the device further comprises a piston driving mechanism, arranged to transfer a force from said weight is propulsion device to the piston to drive it towards said open end; and an expulsion activating mechanism, arranged to engage and disengage the piston driving mechanism in relation to the weight propulsion device.

The invention also relates to a method.

Various embodiments of a ground working implement and a grounds maintenance vehicle that includes such implement are disclosed. The ground-working implement includes an implement frame and a tool carousel rotatably connected to the implement frame. The tool carousel includes a shaft and first and second operator-selectable ground-working tools extending outwardly from the shaft. The shaft extends along a carousel axis. The tool carousel is configured to rotate about the carousel axis and alternately lock in a first position, where the first ground-working tool is configured to contact a ground surface, and a second position, where the second ground-working tool is configured to contact the ground surface.

The present technology relates to a turf striping apparatus. A wiper has a proximal end and a distal end. The wiper defines an elongate loop about a central opening. The elongate loop defines a convex turf contact surface on the distal end having a radius of curvature of at least 0.5 inches. The wiper has a fastening structure towards the proximal end of the wiper configured to be fastened to a working implement.
