Design and Research work:

2003-present Significant design input for the Canadian company, Seed Hawk. This included the design of the world’s largest production air drill (84’) as well as the world’s largest production air seeder cart (800 bushels), along with numerous other machines (400 and 600) and enhancements to existing products. Brought Vaderstad and Seed Hawk together to form a global alliance for the development and marketing of seeding and fertilizing equipment.
2003-2004 Completed design of a complete line of chisel plows including trip mechanisms for Gregoire-Besson in France. Researched various topics and did design work for various companies in the USA and Canada.
2001-2003 Designed and prototyped a close-coupled packer hitch and field sprayer on the farm in Canada. Designed a header sprayer, grain auger and grain cleaner.
2000-2001 Designed machines with Vaderstad, a company in Sweden.
1999-2000 Studied the European market and farm machines and then designed new machines for Flexi-coil that were to be sold into the western European market.
1991-1998 Design engineer for the initial adaptation of the Flexi-coil air delivery technology into the row-crop areas of the Midwest USA. Worked closely with farmers in the row-crop areas and made many trips back and forth to gather design criteria and follow test machines.
Designed various hitches for the air carts and various toolbars and ground openers, as well as high-capacity row-crop air packages to allow the Flexi-coil air carts to apply granular fertilizer at rates exceeding 500 pounds per acre at nine miles per hour. Project manager for the FSO fertilizer soybean opener, the planter/drill concept and the nurse system.
Designed the 8000 Toolbar and was Project Manager for the 8000 Planter/Drill (ASAE AE 50 award winner) and for the 9000 Planting System (ASAE AE 50 award winner). This included the development of the first system in the world capable of nursing corn seed to the row units on 40’ and 60’ precision planters.
Helped with design work on the System 65 Sprayer and was Project Manager for the 340 Chisel Plow.
Involved in patent litigations as an expert witness, helping with preparation and trial support.
Designed the 550-pound trip that is used on the 340 chisel plow as well as the 5000 air drill, 820 cultivator and the 7500 air drill.
Researched and tested numerous systems to enhance the corrosion protection of various components used in the machines at Flexi-coil.

1989-1990            Designed the S-Tine Multi-bar unit (ASAE AE 50 award winner).

1988-1989 Designed the Model S75 wing-up packer drawbar that was introduced in the spring of 1989.
           
1986-1987 Projects at Flexi-coil included the 7” engine driven augers and the 10” PTO driven augers that were introduced in 1987 and produced for a short time at Flexi-coil. The style of the 10” auger was based on a unit that had been designed and built earlier on the farm at Elbow. As a safety feature, the augers were designed without external driveshafts, chains or sprockets toward the discharge end. This concept enhanced operator safety while the operator was near that end of the auger.
Worked on the Model 800 cultivator with Terry Friggstad.
Designed the 350-pound trip that is offered on various tillage and seeding machines at Flexi-coil today including the 5000, 820, 340 and 7500.

1986-present Moved to Saskatoon in 1986 and began working full time for Flexi-coil while continuing on with a hobby farm. Designed a house and had it built. While living on the farm at Saskatoon, a number of machines were designed and built for use on the farm, including a rock-digger attachment for a front-end-loader, small s-tine cultivator for pulling behind a lawn/garden tractor and hopper extensions for a pull-type combine. In addition, a pull-type road grader with lift/angle/tilt functions was designed. Two of the road graders were built; one for use at Flexi-coil to maintain the yard and the other continues to be used to grade laneways at home and for neighbors.

1985-1986 Designed the “Water Cannon” which was a machine used for pumping out small sloughs and pot-holes, at the same time irrigating the adjacent land with the water. A patent was obtained on the “Water Cannon” and a number were built and sold by Flexi-coil.

1984-1985 Designed the 1100 air seeder (ABEX award winner). It was the first in a new series of Flexi-coil air seeders that have been very successful in the marketplace. It incorporated the new fan that had been developed the previous year at Flexi-coil and the metering system from Friggstad Manufacturing Ltd. which was purchased in 1984 by Flexi-coil.

1983-1984            Worked on the design of a new high-efficiency air seeder fan.

1982-1983            Designed truck hoists for Johnson Manufacturing, Hawarden, SK.

1981-1982            Helped with the design and installation of an irrigation project at Elbow, SK.

    • Worked on design projects with Terry Friggstad at Friggstad Manufacturing. Some of the projects included: 300 Series chisel plows in working widths from 22’ to 80’, 650 pound trip mechanism for the chisel plows, a hydraulic-fold coil packer drawbar and the “Pneumatic Applicator” air seeder. These machines, when assembled together, were some of the first air seeders developed for sale in North America.
    • Farmed at Elbow. While farming at Elbow, designed and built numerous machines for the farm including a truck sprayer, a mechanical marker for high-speed truck sprayers, combine chaff spreaders and numerous tow-bars to pull pick-up trucks from field to field behind tractor/implement combinations.

Designed and constructed a substantial addition to the home in Elbow.
In 1978, designed, built and patented a tandem swather hitch for use of the farm at Elbow. This patent was later sold to Macdon Industries and the units were sold commercially.
