Patent number: 10045471Abstract: A soil working apparatus comprises a farm implement including: a first structure moveable above a soil surface along a travel direction; and a plurality of housings, each supporting at least one rotary hoe for forming a furrow in the soil along the travel direction. The housing has a mounting structure for pivotally mounting to the first structure, a radially extending support member having a rotary hoe at the distal end thereof. The rotary hoe mounting structure has a pivot member extending in a plane at right angles to the shaft and the rotary hoe is pivotally mounted to the pivot member for limited composite angular movement relative to a vertical plane and the direction of travel. The rotary hoe may have a star shape including: a central hub, a plurality of spaced apart, radially extending prongs extending from the hub in a common plane, and the prongs each being independently mounted to the hub but interlocked with each other when mounted on the hub.Type: GrantFiled: January 14, 2015Date of Patent: August 14, 2018Inventor: Marcel Depault

Patent number: 8939637Abstract: An apparatus for mixing and pumping manure slurry from a manure pit comprises a pump unit having first and second mixing rotors and a pumping rotor. In operation, the first mixing rotor draws solids downwardly towards the pump unit while the second mixing rotor redirect a portion of the solids drawn by the first mixing rotor away from the pump unit, thereby allowing to control the ration of solid contents in the slurry pumped by the pumping rotor. A non-diverted flow distribution arrangement is also provided for selectively connecting the pump outlet in straight-through flow connection with either a drainage pipe or a re-circulation pipe.Type: GrantFiled: April 8, 2011Date of Patent: January 27, 2015Inventor: Marcel Depault

Patent number: 7497388Abstract: A liquid manure distributor comprises a hollow elongated beam adapted to extend transversally horizontally at a rear bottom end of a spreader. The beam is connected in fluid flow communication with a feed pipe. A plurality of discharged holes are distributed along the hollow elongated beam for distributing the liquid medium from the hollow elongated beam onto the ground surface.Type: GrantFiled: February 14, 2005Date of Patent: March 3, 2009Inventor: Marcel Dépault

Publication number: 20070125561Abstract: A soil working apparatus comprises a first structure moveable above a soil surface along a travel direction and a plurality of second structures connected to the first structure in a spaced apart manner along a direction substantially perpendicular to the travel direction. Each second structure pivotally supports at least one knife selectively pivotable about a substantially vertical axis between a plurality of pivoted positions. A locking mechanism locks the knife(s) of each of the second structures in a selected one of the pivoted positions. The selected pivoted position for the knife(s) of each of the support structures is independent of the selected pivoted position for the knife(s) of other support structures.Type: ApplicationFiled: November 18, 2005Publication date: June 7, 2007Inventor: Marcel Depault

Patent number: 6942237Abstract: A hitch assembly comprises a mounting bracket defining a horizontal through for receiving a drawbar. A pin projects downwards into the through for engagement in a pin slot defined in the drawbar. A wedge is axially insertable into the through for wedging the drawbar therein. A fastener is provided for releasably securing the wedge to the mounting bracket.Type: GrantFiled: April 30, 2004Date of Patent: September 13, 2005Inventor: Marcel Dépault

Patent number: 5772082Abstract: A trailer vehicle for distributing a fertilizing manure slurry to a field which includes a slurry distribution assembly mounted to the tear of the vehicle having four slurry distribution units, each with three plow teeth and a slurry distribution nozzle associated with the teeth for feeding the slurry at root level in the soil. The distribution assembly includes an elongated manifold with four flexible conduits extending from the manifold to each nozzle on the distribution units. The manifold communicates with the slurry tank. The trailer vehicle can also have a special suspension to maintain the tank relatively level. The trailer has three sets of wheels which are articulated in tandem, and the rear wheels of the trailer can be steered in the arc traced by the motive vehicle pulling the trailer. The tank includes an annular wall defining an impeller pump area and a door is hinged to the annular wall.Type: GrantFiled: January 17, 1997Date of Patent: June 30, 1998Inventor: Marcel Depault
