| 20130075117 | AERATOR HOLE SPACING CONTROL - 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. | 03-28-2013 |
| 20130248213 | Aerator - An aerator is disclosed. The aerator features a rotatable tine assembly so as to avoid obstacles or aid in the extrication of the aerator therefrom. The tine assembly includes a plurality of tines mounted about a crank shaft and projecting through said retractor plate. Each tine rod passes between two rollers, one serving as a fulcrum is mounted directly on the retractor plate while the other is mounted upon a spring arm that biases the tine rod as far as possible into a forward position. The aerator is driven by the tines used to puncture the ground. | 09-26-2013 |
| 20130255979 | Aerator With Coring Depth Adjustment - 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. | 10-03-2013 |
| 20130292145 | SLEEVE HITCH MOUNT CORE AERATOR - A tow behind aerator is provided for connected with a hitch of a garden tractor. The aerator includes a connection, a float, a pivot, and an aerator body. The float allows for the aerator to ride on variations of terrain and elevation. The pivot allows the aerator body to pivot or rotate relative to the tractor such that the aerator is able to turn around objects. The pivot may be engaged or disengaged to control the amount of pivot. Further, the aerator includes a self-centering function for centering the aerator when raising the aerator to a non-aerating configuration. A universal sleeve hitch may be used to connect the aerator to the tractor and can be operated to raise and lower the aerator. | 11-07-2013 |
