  • Land roller
    Patent number: 9986672
    Abstract: A land roller is provided with an over-center locking linkage arrangement to help lock a roller frame of the land roller into a raised transport configuration to reduce the likelihood that a failure of the actuator system could cause the roller frame to inadvertently fall and injure a person or cause damage to property. The land roller may be further provided with actuators that are controlled in temporal series from a single controller to simplify and increase the safety of both converting the land roller between the transport configuration and a working configuration and converting side frame sections of the land roller between folded and unfolded positions.
    Type: Grant
