Abstract: An arrow vane protector having a central bore adapted to receive a shaft and nock of an arrow. Extending radially outwardly from the bore are a plurality of slits that are adapted to align with and receive a plurality of vanes attached to the shaft of the arrow. The protector frictionally holds the arrow in place.

Abstract: A roller driven by an engine through a reversible gearbox that is engaged via a belt or chain by a clutch that engages and disengages the belt base on changes in the engine RPM.

Abstract: A shifting system for a vehicle includes an engine with a throttle connected to a transmission. An activating assembly is connected to the transmission, the throttle and a brake. The activating assembly is capable of activating the transmission to change direction.

Abstract: An aerator hole spacing control with a hydrostatic traction drive including a pump and a plurality of wheel motors, a control arm mounted on a control shaft of the pump that controls the direction and the speed of the pump, and a cam follower on the control arm that contacts a cam surface having a minimum coring speed position, a maximum coring speed position, and a transport position. The cam surface may be linked to an operator speed control that moves the cam surface to determine where the cam follower contacts the cam surface to change the speed of the pump anywhere between the minimum coring speed position and the maximum coring speed position without stopping the pump.

Abstract: An aerator having a flexible frame for use on sloped or undulating ground surfaces of golf courses and other turf. The aerator includes a pair of frame sections linked together at a horizontal pivot axis, one of the frame section supporting a coring head. A ground sensor is pivotably attached to one of the frame sections so that the ground sensor may pivot in response to changes in ground slope and provide output relating to the magnitude of the change. Based on the output, a flex frame actuator pivots the pair of frame sections with respect to each other.

Abstract: A turf maintenance device for the aeration and vertical cutting of soil, including a conventional aerator, a vertical cutting device mounted to the aerator, operatively connected to a power source such that the aerator and vertical cutting device may be operated independently and/or simultaneously.

Abstract: A core processing device with a housing having forward and rearward ends, opposite sidewalls, a top, and an open bottom. Wheels operatively connected to the housing. A rotatable brush member connected to the sidewalls for picking up and transporting cores. A shredding member for receiving, shattering, and depositing cores. And a power means for driving the brush member and shredding member.
