A BRIEF HISTORY OF WEISS McNAIR 1966 - Gary Weiss starts full time production factory build of twenty-five (25) Weiss Orchard Sweepers, powered by a six (6) horsepower Briggs & Stratton engine, with the entire inaugural production run selling out at its first showing, the Colusa Farm Show. And a star is born. 1968 - The Weiss Orchard Sweeper is upgraded to include a more powerful 8 h.p. Kohler engine. 1968 – Dan McNair staffs up for his first production harvesters, known as the “Getzumall”, a name that was adopted after many conversations with the first users of the harvester prototypes, who would frequently remark, “Yep, it’s a good dependable machine, it sure Gets ‘um all!” The original harvester had just an 18” elevator chain, no suction, or vacuum fan, and only one small blower fan under the elevator. 1969 - The Weiss Orchard Sweeper was upgraded to include a blower unit and a 12 h.p. Kohler engine as standard. 1972 – Tractor Mounted Sweeper designs were added to the growing line, becoming extremely popular worldwide. The economic value to the farmer was exceptional. The farmer was able to leverage the assets already held (tractors) by adding/configuring them with Weiss Sweeper attachments, up to a full eleven (11’) feet wide, without incurring the significant cost of an additional powertrain unit. 1972 – Gould Paper Company acquires McNair Nut Harvesters from Dan McNair and Robert Pierce. 1973 – Weiss introduces the Tractor Mounted, Center Delivery, thirteen (13’) foot wide Sweeper. 1974 – December, the Weiss Orchard Sweepers Company is acquired by Gould Paper Company. 1975 – Weiss designed and introduced a 3-point tractor powered blower. Used primarily in orchards, they have gained wide acceptance in a variety of applications including use in Poultry Production Houses; Cattle Field Yards; City, County & State Road Maintenance departments; Construction companies; Golf Courses across America; and several NASCAR race tracks. 1968 - 1982, both Gary Weiss and Dan McNair updated and enlarged their product offerings as orchards and production yields increased and larger horsepower tractors evolved. In 1968, most tractors were in the 30-40 h.p. range. Today, 70 h.p. is common in Almond orchards and 140 h.p. in Pecan orchards. Throughout the 1970’s both companies gained worldwide recognition as their overseas markets expanded and export busi

1983 – Gould merges Weiss and McNair into a single company, forming Weiss/McNair, Inc, and providing worldwide customers the first combined harvester/sweeper manufacturer, significantly improving field service and replacement parts support, through an exceptional and expanded network of regional dealers. The merger was also significantly beneficial for the company, as the combined engineering resources coalesced into a truly formidable Research & Development team; and the operational efficiencies gained with much higher volumes, streamlined fabrication, welding, and assembly processes, and the...
