Argo vehicles are built by Ontario Drive & Gear, a Canadian company based in New Hamburg, Ontario, whose history stretches back to the 1960s. The first Argo amphibious vehicle appeared in 1967, and the design, a sealed body with six or eight driven wheels that propel the machine on land and paddle it through water, has been refined continuously since. It is a genuinely different kind of off-road vehicle.

Argo is known for machines that go where other vehicles cannot: across mud, marsh, shallow water, snow, and forest. This capability has made Argos standard equipment for search-and-rescue teams, utility companies, fish and wildlife agencies, hunters, and farmers, and they have earned a strong following among outdoor workers worldwide. Their amphibious ability sets them apart from conventional ATVs and UTVs.

Argo workshop manuals document the full vehicle: engine service and overhaul, belt-and-chain final drives with adjustment procedures, the skid-steer transmission and braking system, axles, bearings, and seals, plus electrical and wiring diagrams, torque specifications, troubleshooting, and factory maintenance schedules. Because Argo machines operate in water and mud, correct sealing and drive maintenance is critical.

Owners and operators, independent mechanics who work on off-road equipment, and buyers of older used Argos will all find the manuals useful for keeping these specialized machines reliable. Sound service documentation is part of owning a vehicle that is expected to work far from help.
