TODAY’S PATENT – LAND ROLLER

The land roller was invented by Barry W. Smyth, Matthew D. Thomson on 14th September 2017, bearing patent number US20170257996A1.

The present invention relates to 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.

Land rollers are often provided with a hydraulic system for pivoting the wheels to convert the implement between the transport configuration and the working configuration. Additionally, land rollers are often constructed with side sections or “wings”, which have further hydraulic systems for pivoting the side sections between a substantially horizontally oriented (unfolded) position and a substantially upwardly oriented (folded) position. Upwardly folding the side sections narrows the overall width of the implement to permit the implement to be better towed on a public road.
