  • Walk aerator
    Patent number: 9462738
    Abstract: A walk aerator comprises a housing supported by a plurality of wheels that include a pair of drive wheels. The drive wheels are pivotally mounted to the housing to permit the housing to move between operational and transport positions thereof. A control is used to so move the housing with the control having a hand grip whose height above the ground is easily adjustable to accommodate users of different effective heights. A foot guard maintains a relatively constant disposition relative to the ground whether the housing is in its operational or transport position. The housing of the aerator has a vent system and an air gap relative to a prime mover deck which cool a traction drive system contained within the housing.
