Weiss McNair

What Weiss McNair does

Orchard Machinery Corporation, doing business as OMC and commonly referred to as Weiss McNair, is a family-owned US manufacturer specializing in mechanical harvesting equipment for tree nuts and fruits. Founded in 1961 and headquartered in Yuba City, California, the company designs and builds an integrated product portfolio that includes Shockwave tree and limb shakers, self-propelled sweepers, harvesters and conditioners (notably the Catchall X off-ground harvester for pistachios), Aftershock shuttles and bin carriers, Aftershock elevators, blowers, transport carts, and orchard maintenance equipment. OMC also serves as the exclusive US distributor for TOL Incorporated pruning machines. The underlying technology is purely mechanical, centered on trunk-vibration harvesting, ground-sweeping collection, and in-field material handling — all engineered for the time-critical harvest windows of California almond, walnut, pistachio, and fruit operations.

OMC generates revenue primarily through hardware sales of new harvesting and orchard equipment to commercial orchard operators, supplemented by aftermarket parts, service, and pre-owned equipment sales. Pricing is quote-based and not publicly disclosed, consistent with high-value industrial machinery sold through configuration-specific dealer consultation. Go-to-market relies on a US-wide dealer network for localized sales, parts, and service, supplemented by direct manufacturer engagement (including a "Request a Demo" CTA) for enterprise accounts. The company operates a single-country footprint in the United States, with no disclosed international expansion or institutional investment.

The company has operated continuously for over 60 years under family ownership, without disclosed M&A, leadership changes, regulatory actions, or external funding rounds. Its competitive position rests on specialized domain expertise, an established dealer channel, brand longevity in the California tree nut and fruit growing region, and an aftermarket parts/service business tied to an installed base of equipment in commercial orchards.
