Abstract: Tine assemblies (100a, 100b, 104) are secured by a single bolt (126) extending diametrically through each tine (120) located in a cavity (112) of a tine plate (110). An outer tine assembly (104) is connected to a sleeve (116) rotatably mounted on independently rotatable shafts (102) to which inner tine assemblies (100a, 100b) are connected. A tine cover (50) removably closes an opening (40) in the top plate (28) and in which weights (70) are removably received over the tine assemblies (100a, 100b, 104). Transport wheels (134) are moveable by pivoting a stop plate (140) to position an upper pivot axis (150a) of an abutment bar (150) ahead of or behind the stop axis (142) and lower pivot axis (150b). A stop (146) positioned on the stop plate (140) without the use of tools adjusts the depth of the tine assemblies (100a, 100b, 104).

Abstract: Optional attachments, such as a drop seeder and a sprayer unit, can be removably attached to the front plate of a turf aerator. The attachment includes a hitch slideably received in a tubular receiver and pinned therein by a pin. A lock is pivotal relative to the attachment from an unlocked position to a locked position with the front plate received in slots of the lock. The lock is pivoted relative to the attachment by a rod which is threadably received in the hitch. Valve openings in a valve plate are aligned or mis-aligned with lower openings formed in a hopper mounted to the hitch by a linear electric actuator. A lever is pivotably mounted to a housing which is removably attached to the chassis of the turf aerator and activates the linear electric actuator and a switch controlling an agitator. A valve is alternately in fluid communication with a spray nozzle mounted relative to the hitch and a spray wand.

The attachment ring (130) of an outer tine assembly (104) is connected to a sleeve (116) rotatably mounted adjacent the outer ends on each of two independently rotatable shafts (102) to which inner tine assemblies (100a, 100b) are rotatably connected adjacent the inner ends of the two independently rotatable shafts (102). The attachment rings (130) of the inner tine assemblies (100a, 100b) are welded to the two independently rotatable shafts (102).

Abstract: 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.

Abstract: A top dresser (10) includes a spinner assembly (40) removably connected by clips (44) to a cross beam (20) of the frame (12) mounting a hopper (30). The first and second sides (36) of the hopper (30) slope downwardly and inwardly to a conveyor (140) formed by sheeting (70) in the form of an endless belt having a relatively smooth outer surface. The valve (84) for the hydraulic motor (164) of the conveyor (140) is in series downstream of the valve (78) for the hydraulic motors (56) for the spinners (54) of the spinner assembly (40). Thus, it is not possible to mistakenly run the conveyor (140) without the spinners (54) operating. Therefore, the top dresser (10) is able to spread extremely minimal amounts of material evenly and without clumping or bunching.
