Abstract: An improved turf aeration device is provided, where the device has a frame having a journalled drive shaft, and the frame is attachable to a pulling vehicle having a power take-off portion; where the device has a power transfer means, attachable between the drive shaft and the power take-off portion, for transferring power from the power take-off portion to the drive shaft; and a plurality of aerator mechanisms operatively attached to the drive shaft and the frame, each aerator mechanism having a lower link member, with a base end and a distal end, where the base end is pivotally attached to the frame; a tine holder pivotally attached to the distal end of the lower link member, where the improvement includes a roller frame rigidly attached to the frame, the roller frame having two spaced apart, and a slideable member adapted to allow limited rotation of the aeration device toward or away from the pulling device.

Abstract: A hitch system attachable between a towing utility vehicle and a towed device, where the utility vehicle has a power source. The hitch system has a first frame adapted to pivotably couple the towing vehicle and the towed device, a lift frame attachable to the utility vehicle, where the lift frame has a first member and a second member and the second member is pivotably connected to the first member. The second member is operationably connected to the power source to pivot the second member in relation to the first member. The second member has a tow point, which is offset from the centerline of the second member, enabling the towed device to be towed in an offset configuration. Finally, a top link pivotably connects the second member and the utility vehicle, the top link connecting at the tow point.

Abstract: A turf aeration device is provided, comprising a wheeled frame having a journalled drive shaft, wherein the frame is attachable to a pulling vehicle having a power take-off capability. Balanced chain and sprocket assemblies are used to transfer power from the power take-off to the drive shaft, and a plurality of aerator mechanisms are attached to the drive shaft and the frame. Each aerator mechanism comprises a link member which supports a pivotable tine holder having at least one tine, a stop member attached to the link member for contacting the tine holder and maintaining a minimum predetermined angle between the tine holder and the link member; a means for adjusting the predetermined angle between the tine holder and the link member; an elastomeric band pivotally connected between the frame and the tine holder for urging the tine holder against the stop member; a drive link attached to the drive shaft; and a connecting rod pivotally attached between the drive link and the link member.
