Abstract: A broadcast spreading top dresser (10) includes a diverter (200) which can be positioned in an upper position for light applications and a lower position for heavy applications, with the diverter (200) extending through a slot (210) in an upper sheet (58) of the spinner assembly (40) and beyond and below the upper sheet (58) in the lower position. The leading edges (204) of the diverter (200) are spaced from the circular disks (154) of the spinners (54) intermediate the radial position that the material is dispensed unto the spinners (54) and the maximum rearward extent of the circular disks (154). The lower edges of the diverter (200) extend at differing distances into the thickness of the propelled top dressing material.

Abstract: An aerator that allows the operator to make a turn with the machine while the tines are still in contact with the turf through the use of a differential shaft and brakes that enhance the maneuverability of the machine. The aerator is fitted with a mechanical gear type differential on an intermediate drive shaft that provides for automatic, separate and variable rotational motion of the individual halves of the tine shaft. This differential apparatus also provides constant and equal torque application to both sides of the tine wheel assembly simultaneously while the machine is operating. This insures that tine penetration into the turf is equal on both sides at all times. The tine shaft halves are designed and mounted in such manner as to allow each half (left and right sides) to be driven by separate chains from the differential shaft. This design results in a desired variation in the speed of rotation of the two halves that facilitates turning the unit.
