  • Patent number: 12114585
    Abstract: 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.

  • Patent number: 11849657
    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.

  • Patent number: 11832541
    Abstract: Tines (120) of 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), through the tine plate (110) and through an attachment ring (130). 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).

  • Patent number: 11083184
    Abstract: An applicator includes a spinner rotated by the parking brake output shaft of a hydrostatic transaxle driving first and second drive wheels. Material delivered from a hopper on the spinner is spread by the spinner rotating at a speed corresponding to the rotating speed of the drive wheels. Liquid is sprayed by either a trim nozzle intermediate sides of the frame or broadcast nozzles adjacent the sides of the frame. A spray lever is pivoted to slide a slide linkage from an upper position to a lower position abutting with a biased actuator of an on/off valve, with the spray lever and a spinner gate opening lever operable at the same time with just one hand. During transport, a front bumper is received in a horizontal leg of an L-shaped slot and a cutout in an arm pivotably mounted to a stop in which the L-shaped slot is located and in a locking position. A locking pin is inserted through apertures in the arm and the stop in the locking position.

  • Patent number: 10194582
    Abstract: An apparatus applies product and includes a pivotal platform solely supported through bushings formed of compressible material. The ground speed can be locked by stepping on a step pivoting a composite block to engage with an engagement of the transmission proportioner arm. A gate is opened utilizing a control lever pivotally mounted to a pivotably mounted control block to either engage or avoid a tang of an adjustment guide. A drive belt system includes a variator having first and second sheaves having variable effective diameters when their pivot pin is moved by pivoting a lever. A spray tip sprays a fan style spray at a small acute angle to the application area. A flip shield is pivoted about an axis parallel to the movement direction and includes a linear straight portion parallel to the axis in a redirection position.

  • Patent number: 9986692
    Abstract: A debris blower includes an engine mounted to an engine mount and connected to a turbine. The engine mount and housing of the turbine are respectively mounted between a second side of a frame and first and second longitudinal supports connected to and between first and second sides of the frame. A screen guard is secured utilizing bolts extending in a non-rotatable manner from a top plate connected between the second longitudinal support and the second side. Due to the frame and engine mount having a parallelism and flatness tolerance, the engine and turbine can be aligned without shimming. A sensor senses first and second trip devices positioned at circumferential locations on the exit nozzle to rotate the exit nozzle to preset angles. Remote and hard wire controls each include direction and speed switches. A resume switch throttles the engine between idle and operating speeds.

  • Patent number: 9491902
    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.
