SCAG POWER EQUIPMENT - Split Steel Pulleys

Scag Split-Steel Pulleys

Scag mowers feature split-steel pulleys for increased strength, reliability and reduced wear on pump and cutter deck drive systems. Split steel pulleys are lighter in weight and stronger than cast iron. They are also stronger than stamped pulleys.

As split-steel pulleys are made from a single piece of steel, no balance holes are required, unlike a cast pulley where they must be balanced and drilled. These drill points for balancing can create weak points.

The reduced weight (less rotational inertia) of the pulleys makes it easier for blades and other drive components to rotate up to speed. They also allow the electric clutch brake to stop the cutter blades faster with less wear on the clutch rotor and armature. In short, the split-steel pulley design adds to the life of drive components and reduces maintenance time and cost.
