Patent number: 10039225Abstract: A land roller implement includes a wheel aligned with the respective gap between the inner roller and the outer roller of each wing in which the wheel is pivotal between a packing position in the working position of the rollers and a transport position supporting the rollers in the transport position of the implement. The wings can also include a drive motor associated with each transport wheel to drive forward rotation of the wheel for displacing the wings from the transport position to the working position without displacing the implement in a rearward direction. A levelling beam attachment and a seeding attachment can also optionally be used on the land roller implement. Optional latchable brace members pivotally supported on the wings may provide additional support to the wings when using the levelling beam attachment.Type: GrantFiled: November 16, 2016Date of Patent: August 7, 2018Assignee: AG Shield Ltd.Inventors: David Gary McCrea, Thomas Edward McCrea

Patent number: 9820434Abstract: The stripper is a flange member supported on the upright backboard of a crop harvesting header to span a gap between the backboard and a cross auger. The cross auger is supported above a draper on the header to assist in guiding the cut crop being conveyed by the draper to a central rear discharge of the header. The stripper flange member extends forwardly towards the cross auger at an upward inclination so as to be oriented at an angle of greater than 90 relative to a portion of the backboard of the header immediately below the stripper flange member. The stripper flange member is thus better oriented to guide cut crop which rises up the backboard to be deflected forwardly into the cross auger, instead of acting as a stop to accumulate cut crop thereon when the flange member is oriented perpendicularly to the backboard.Type: GrantFiled: January 27, 2016Date of Patent: November 21, 2017Assignee: AG Shield Ltd.Inventor: Thomas Edward McCrea

Patent number: 7040552Abstract: An applicator boom apparatus comprises an applicator boom extending laterally from a vehicle, and pivotally attached to the vehicle such that the boom can pivot up and down with respect to the vehicle. A kit provides a gauge member adapted to ride along a surface of the ground and support an outer portion of the boom such that the boom moves up and down with the gauge member as the gauge member rides along the ground, and also provides an active hydraulic source powering the shoulder hydraulic cylinder of the apparatus such that the shoulder hydraulic cylinder exerts an upward force on the boom such that a downward force exerted on the gauge member by the boom is reduced.Type: GrantFiled: October 15, 2003Date of Patent: May 9, 2006Inventors: David Gary McCrea, Thomas Edward McCrea

Patent number: 6457302Abstract: A crop divider for separating crop plants on one side of a line of travel from those on an opposite side of the line of travel and pushing the plants away from the line of travel to allow passage of an implement portion along a forward travel path while reducing contact of the plants with the implement portion. The crop divider comprises a vertically oriented V-shaped member adapted for mounting on the implement forward of the implement portion, the V-shaped member having an apex located substantially in the center of the travel path and facing forward, and right and left legs extending rearward and outward beyond edges of the travel path. A vertically oriented cutter is mounted on a forward edge of the apex of the V-shaped member. The crop divider is particularly suited to a canola pusher for lodging crops of the Genus Brassica.Type: GrantFiled: September 8, 2000Date of Patent: October 1, 2002Inventors: Thomas Edward McCrea, David Gary McCrea
