Publication number: 20240026634Abstract: A bucket for a loader includes a main body and a pair of swing plates pivotably coupled to the main body for defining an exterior collection space for gathering material from the ground surface when operating the bucket in a back-dragging mode. Each swing plate is pivotable relative to the main body between a first position and a second position. When in the first position, the swing plate lower edge is raised above an outer surface of the bottom wall. When in the second position, the swing plate protrudes past the outer surface of the bottom wall, with inwardly directed faces of the swing plates cooperating with an outer surface of a bottom wall of the main body to partially enclose an exterior collection space when back-dragging.Type: ApplicationFiled: July 19, 2022Publication date: January 25, 2024Inventors: Gerard F. Bourgault, Kevin Punk

Patent number: 7975630Abstract: A method for controlling a seeding apparatus including sensing a ground force acting on a furrow opener of the seeding apparatus and providing a ground force sensor signal in dependence upon the ground force acting on the furrow opener. The method further includes providing an actuator to apply a bias force to a packer wheel of the seeding apparatus. The method also includes providing a control device operative to receive the ground force sensor signal and an input from an operator and to adjust the bias force that the actuator applies to the packer wheel in dependence on at least one of the ground force sensor signal and the input from the operator.Type: GrantFiled: November 15, 2010Date of Patent: July 12, 2011Assignee: Bourgault Industries Ltd.Inventors: Gerard F. Bourgault, Mark Cresswell

Patent number: 6260632Abstract: A coulter assembly is provided to create furrows in a field, while at the same time reducing the amount of soil and debris which accumulates on the coulter disc. The coulter assembly has a disc for creating furrows, with a floating scraper blade on the inner side to keep the inner side of the disc free of debris. The scraper blade also assists in maintaining the furrow once it has been opened by the disc. The scraper blade has a leading edge constructed of carbide and inserts attached to the scraper blade for reducing wear on the scraper blade during operation. A tine extends across the outer side of the disc in a configuration that prevents soil from adhering to the outer side of the disc, and in trash covered fields, trash will wrap around the tine to act as an organic wear pad between the disc and the tine.Type: GrantFiled: March 15, 1999Date of Patent: July 17, 2001Assignee: Bourgault Industries Ltd.Inventors: Gerard F. Bourgault, Peter Kondratowicz, Jr., Ron Allan

Patent number: 5251704Abstract: There is disclosed a new and improved rearwardly folding combination harrow sprayer drawbar. A plurality of quick detach harrow arms are adapted to be quickly connected and disconnected to a plurality of harrow arm receivers. The implement can be used for spraying and harrowing at the same time, or once the harrows are detached and left in the field, the implement can be used for post-emergent spraying. A wet spray boom can be height adjusted by means of a plurality of manual spring loaded levers. The unit is equipped with hinged boom draws which can be pinned to be rigid such that it can be moved rearwardly in order to re-attach the harrows quickly and easily. The unit is also capable of lifting the harrows into a transport position and folding rearwardly into a narrow transport position in order to pass over roads or move through narrow entrance ways.Type: GrantFiled: January 31, 1992Date of Patent: October 12, 1993Assignee: F.P.

Patent number: 4993499Abstract: A wing packer has a middle frame section and two wing frame sections to which rollers are attached. The packer can be converted to a transport position by a hydraulic system which lifts the middle section and pivots the wing sections upward. The rollers are connected to the frame about a two-axis pivot which facilitates their remaining in contact with the ground on uneven terrain.Type: GrantFiled: September 26, 1989Date of Patent: February 19, 1991Assignee: F. P. Bourgault Industries Air Seeder Division Ltd.Inventors: Gerard F. Bourgault, Richard P. Coquet
