Toro Snow Blower S-620 Specifications

Engine

• The Toro S620 has a Tecumseh 2.5 horsepower engine. Most Toro snow throwers in this class were manufactured with Tecumseh engines. The two-cycle motor type is categorized under the Toro model number AH600-1623P. The snow blower had a 20-inch swath. This is the amount of coverage the snow thrower provides during operation.

Gas and Oil

• The engine uses Toro 2-cycle/NMMA-TCW3 engine oil, like most other Toro models ranging from 2 to 4.5 horsepower. The mix ratio for the Toro S620 model is 50:1. In order to achieve the right gasoline-to-oil mixture add 2.6 ounces of oil for every gallon of gasoline. Add the mixture in order to start the Toro S620.

Ignition

• The manufacturer makes the ignition of coils with air gaps that measure .013 inches. The company made the Toro S620 with Champion RCJ8Y spark plugs gapped at .030 inches. The spark plugs are pivotal to the engine starting in cold weather. Faulty spark plugs will burn more gasoline and, at worst-case scenario, prohibit the engine from starting.

Starter

• The Toro S620 can operate on electricity provided by an extension cord as well as on gasoline. To start the snow thrower, pull the choke and press the primer until the engine turns over. In cold weather, you may have to do it several times, depending on how cold the unit is. When you press the primer, it pumps gasoline into the carburetor, which helps start the engine.
