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.

An aerator with coring depth adjustment includes a coring depth adjust rod centrally positioned between a left side and a right side of the coring head. A portion of the coring depth adjust rod is threaded to a frame member of the coring head, and a base of the rod abuts a stop on a frame member of the aerator. The coring depth adjust rod rotates to raise and lower the coring head relative to the aerator frame to vary the coring depth.

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.

Aerator hole spacing control

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.

The lawn mower includes a vehicle body supporting front and rear wheels and a mower unit suspended from the vehicle body between the front and rear wheels by front and rear links. The links are movable to raise and lower the mower unit. A grass striping mechanism is associated with the vehicle body. The mechanism includes a stay arm connected to the mower unit and a roller support member movably connected to the stay arm so that the member is capable of movement in a vertical direction. A grass striping roller is rotationally supported by the roller support arm. A lift link is pivotally connected to the vehicle body and is associated with the roller support member. The lift link interfaces with the rear link such that upward movement of the rear link imparts movement to the lift link and roller support arm to lift the roller from the ground.

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.

Turf maintenance device for aeration and vertical cutting of soil

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.
