Patent number: 6584920Abstract: A system for maintaining an appropriate air flow in an air stream in an air seeder. A fan provides an air stream to carry agricultural materials for distribution across a width of a seeding implement. A tank contains a granular agricultural material and a metering device dispenses the material into the air stream. The system is calibrated such that a known weight of material is dispensed for each revolution of the metering device whereby the rotational speed of the metering device multiplied by the known weight per revolution results in a known per minute rate of agricultural material being dispensed into the air stream. A microprocessor is programmed to derive an appropriate fan speed for the per minute rate of agricultural material being dispensed and send a signal to a fan control to adjust the speed of the fan to correspond to the appropriate fan speed.Type: GrantFiled: September 17, 2002Date of Patent: July 1, 2003Assignee: Bourgault Industries Ltd.Inventor: 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.

Patent number: 6237697Abstract: Disk coulters are used on numerous soil engaging farm implements to cut furrows into which seed or fertilizer can be deposited. Disk coulters may also be used to cover furrows or simply cut trenches in the land. Typically, an implement or tool bar frame may have several disk coulter assemblies attached to the frame. Some are dedicated to inserting seed into the soil and other fertilizer. In an alternate configuration, the implement or tool bar may have a combination of shanks and coulters. In any given application it may not be necessary to use some of the coulter disks assemblies. Because of the wear on coulters as they move through the soil and encounter rock and other debris, it is advantageous to be able to quickly lift some of the coulter disks out of the soil while operating with other disks. The present invention provides an eccentric rotating element attached to a spring which generally in operation exerts force upwardly on the coulter arm and therefore maintains the coulter in a downward position.Type: GrantFiled: July 19, 1999Date of Patent: May 29, 2001Assignee: Bourgault Industries, Ltd.Inventors: Robert Butterfield, Gerard F.

Patent number: 6216616Abstract: A coulter closing wheel assembly, a method of planting, and a mid row banding pneumatic coulter drill assembly support vehicle. One fertilizer coulter is positioned between two seeding coulters. The seeding coulters are followed by a furrow closing disc which scrubs the ground and pushes soil back into the furrow. The seeding coulters are also followed directly by a packer wheel. The fertilizer coulters may or may not employ a furrow closing disc, depending on the type of fertilizer and the type of soil. In the event of granular or liquid nitrogen fertilizers the closing disc is generally not necessary. However, when a gaseous fertilizer such as anhydrous ammonia is applied to the soil, the furrow closing disc is necessary in order to prevent the escape of the anhydrous ammonia into the atmosphere. The coulters are firmly attached to horizontal frame members of the drill and placed at an angle of a few degrees off the direction of travel.Type: GrantFiled: July 19, 1999Date of Patent: April 17, 2001Assignee: Bourgault Industries Ltd.Inventor: Gerard F.

Patent number: 6042326Abstract: In a grain cart equipped with a lower horizontally-disposed input drag auger, a vertically disposed lift auger, and an upper horizontally disposed discharge auger, a unique drive train is used. The lift auger and the discharge auger can be activated independently of the input auger in order to empty their contents on start-up of the grain cart discharge system. By so doing the strain on the drive train is considerably lessened thus permitting very large grain carts to be emptied without damage to the drive train system. A hydraulic cylinder activates a belt-tightener between a drive sheave and a driven sheave. The driven sheave is attached to the axis of the drag auger. When the hydraulic cylinder is extended, pressure exerted on the belt causes the input auger to rotate and to feed the lift and discharge augers.Type: GrantFiled: July 16, 1998Date of Patent: March 28, 2000Assignee: Bourgault Industries Ltd.Inventors: Dean Thomas, Darren Borstmayer, Ronald Allan
