Abstract:
In a landscape rake including a rotatably operable rake mechanism for performing a raking function, a bucket for receiving material raked by the rake mechanism, and a fluid actuator connected to the rake mechanism operable for moving the rake mechanism relative to the bucket, the fluid actuator having a first port adapted for connection to a source of pressurized fluid for receiving the pressurized fluid therefrom for moving the rake mechanism to a position proximal to the bucket and a second port adapted for connection via a fluid path to a fluid receiver for discharging fluid thereto, the improvement comprising a fluid control system for the fluid actuator including a second fluid path connecting the first port of the fluid actuator with the first named fluid path and a valve disposed in the second fluid path operable for allowing fluid flow therethrough from the first port to the first named fluid path while preventing fluid flow from the first named fluid path to the first port to allow the rake mechanism to float when in the position proximal to the bucket.
