Engine

The Toro Snow Commanders are powered by a high

output version of the R tek engine (Figure 1). The main

difference between the standard R tek and the version

used on the Snow Commander is in the piston and

cylinder.

The piston has two additional square ports (Figure 2),

which line up with two grooves machined in the

cylinder wall (Figure 3). As the piston goes down and

compresses the fuel/air charge in the crankcase, the

ports in the piston uncover the grooves in the cylinder

wall. This provides extra area for the fuel charge to

move to the firing chamber. The result is a larger fuel

charge, which makes more power.
