  • 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.

  • Publication number: 20210076553
    Abstract: A turf aerator is disclosed which 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: 6058860
    Abstract: The seeder apparatus includes a first hopper for dispensing seeds onto a conveyor mechanism to be moved thereby to an entry nip between a rotary brush and the conveyor mechanism for propelling the seed downwardly at the discharge end of the frame on which the hopper is mounted. A shield assembly is mounted to the frame discharge end portion to minimize the effects of wind on the trajectory of seed or other material being propelled to the ground by a brush and conveyor mechanism. In one embodiment, a metering gate extends vertically in its closed position relative to the conveyor mechanism, the metering gate controlling the rate of dispensation of seed being moved to the entry nip.

  • Patent number: 6024033
    Abstract: The seeder apparatus includes a material hopper for dispensing material onto a conveyor to be moved thereby to an entry nip between a rotary brush and the conveyor for propelling the material downwardly at the discharge end. In one embodiment, a metering gate extends vertically in its closed position relative to the conveyor, with the metering gate controlling the rate of dispensation of seed or other material being moved to the entry nip. A shield assembly is provided to minimize the effects of wind on the trajectory of seed or other material being propelled to the ground by the brush and conveyor. In preferred forms, a separate seed hopper is mounted to the top dresser, and in a second embodiment, either seed from the seed hopper and/or dressing material from the top dresser hopper may be moved by the conveyor to the entry nip.
