  • US Classification:
    239668, 239672, 239673, 239676, 239679, 239680
  • Abstract:
    A broadcast spreading top dresser ( ) includes a diverter ( ) which can be positioned in an upper position for light applications and a lower position for heavy applications, with the diverter ( ) extending through a slot ( ) in an upper sheet ( ) of the spinner assembly ( ) and beyond and below the upper sheet ( ) in the lower position. The leading edges ( ) of the diverter ( ) are spaced from the circular disks ( ) of the spinners ( ) intermediate the radial position that the material is dispensed unto the spinners ( ) and the maximum rearward extent of the circular disks ( ). The lower edges of the diverter ( ) extend at differing distances into the thickness of the propelled top dressing material. The metering gate ( ) is prevented from being inadvertently manually pivoted between first and second ranges of spacings from the conveyor ( ) by a stop ( ) having a spring based plunger ( ), with the free end of the plunger ( ) sliding on the face of the side plate ( ) of the metering gate ( ) in the second range while the plunger ( ) abuts with an edge of the side plate ( ) in the first range.

  • International Classification:
    B65G 23/04
  • US Classification:
    198835, 198813, 198842
  • Abstract:
    A top dresser () includes sheeting () in the form of an endless belt passing around first and second drums () and a bed () including a plurality of rollers (). Continuous V-shaped guides () are received in pulleys () on the drums () for tracking the endless belt. A blocking device () in the form of a rod is slid in the mid-frame () to prevent the shafts () of the rollers () from axially sliding against their bias from their operative positions to their installation positions. Ledges () having friction reducing strips () extend over the shafts () of the rollers (). A compound gear () in gearing relation with the second drum () and in driving relation with a spindle () of a brush () is rotatably mounted to an arm () pivotally mounted to the second drum (). The spindle () includes two portions () removably connected by a coupler (), with the first portion () being cantilevered supported from the side frame ().

  • Method And Apparatus For An Aerator With Differential, Steering Assist And Power Lifting

  • US Patent:
    20040154811, Aug 12, 2004
  • Filed:
    Feb 9, 2004
  • Appl. No.:
    10/774936
  • Inventors:
    John Kinkead - St. Paul MN,
    Loren Hansen - Lincoln NE,
    Donavon Kotula - Apple Valley MN,

  • International Classification:
    A01B045/00
    A01B045/02
  • US Classification:
    172/021000
  • 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. The differential mechanism is also functional in driving the transport rollers at the front of the machine. The improved aerator is also fitted with brakes installed on each side of the unit which can reduce the speed of rotation of the separate tine wheel halves and the individual drive rollers on the front of the unit, thus increasing the steering efficiency and a spring-actuated lift assist to help the operator raise the unit into the transport position. The aerator includes heavy duty springs on both sides of the unit to apply equal forces to both of the transport wheel lift members. A release mechanism operated from the handle bar is provided to allow the operator to disengage the retaining latches, which will allow these springs to pull the transport wheels under the unit thus raising the tine shaft halves. The aerator also incorporates drums of sufficient mass so as to not require the addition of water or other additional weighting methods.
