A turf aerator is configured with components that allow a user to set a desired turf aeration depth and then automatically adjust hydraulic pressure to produce a proper level of downward pressure into the ground in order to maintain consistent depth penetration with the tines. The turf aerator implements a depth control lever that is operatively connected to a switch that increases or decreases tine depth up or down. Since the desired tine depth is set and the hydraulic pressure is capable of puncturing the ground accordingly, portions of the ground that are relatively harder or softer are still properly penetrated due to the set level of depth. The turf aerator is also configured with a tine housing which shields drive chains from dirt and debris from the aerating, thereby increasing the life of the drive chains.

Methods and apparatus for aerating turf

A top dresser advances sand contained in a hopper on a dispensing conveyor moving at a linear speed onto a rotatable spinner rotating at a rotating speed. The linear and rotatable speeds are controlled by a controller by electrically actuating first and second electrically actuated valves providing fluid flow to hydraulic motors driving the rotatable spinner and the dispensing conveyor. The rotatable and linear speeds are inputted into an electrical display electronically connected to the controller. The hydraulic flow to the second electrically actuated valve may be solely from the first electrically actuated valve to create back pressure acting as a cushion. Multiple function switches on the electrical display may be actuated in sequence to replicate a linear line relationship between the rotational and linear speeds. Start-up, run, look up and application calculation screens may be displayed on a monitor of the electrical display.

A seeder () includes multiple cutting head units () pivotally mounted to a jack shaft () of a frame () and spring biased downwardly by hold downs (). Each multiple cutting head unit () includes multiple roller blades () received on an axle () rotatably mounted in a carrier () and in gearing relation to the jack shaft (). The roller blades () include a series of oppositely formed, circumferentially spaced radially extending indentations () extending from a continuous, smooth periphery at a constant extent from the axle (). Fingers () extending between the roller blades () are pivotally mounted to the carrier () to adjust the depth of the slits formed by the roller blades (). Each hose () extending from a seed box () diverts seed into adjacent slits immediately after the roller blades ().
