Stens 280-882 Flat Idler Pulley

The Stens 280-882 is a steel flat idler pulley designed as a direct replacement for Exmark part 1-603497. It fits Exmark Explorer, Explorer II, Turf Ranger, Turf Tracer walk-behinds and Viking mower decks. This part maintains proper belt tension on compatible commercial mowing equipment.

Verify Your Exmark Model and Deck Size

Confirm that your machine is an Exmark Explorer, Explorer II, Turf Ranger, Turf Tracer with a 52 or 60 deck or a Viking with a 32, 36 or 48 deck before ordering. Check the original pulley for the OEM number 1-603497 to ensure correct fitment. Measure the centre hole and overall diameter if the model tag is missing.

Steel Construction with Standard Mounting Dimensions

The pulley is made from steel with an outer diameter of 4 3/4, an inner diameter of 11/16 and a height of 1 1/4. These dimensions allow it to bolt onto the existing idler arm using the original hardware. The flat profile keeps the belt running true on the specified Exmark and Viking decks.

Questions about this item

What comes in the box with the Stens 280-882 flat idler and is any extra hardware needed?

The box contains one flat idler pulley. No extra hardware is included; reuse the original bolt and washer from the mower deck.

How do I choose the right version of the Stens 280-882 for my Exmark deck?

Match the pulley to the deck width: it fits Viking 32, 36 and 48 inch decks and Turf Tracer 52 and 60 inch walk-behind decks.

What does the 4 3/4 inch outer diameter mean once the idler is installed on the mower?

The 4 3/4 inch OD matches the OEM Exmark 1-603497 size so the belt tracks at the correct radius and tension on Explorer, Explorer II, Turf Ranger and Viking decks.
