Stens 238-037 Belt for Toro Mowers

This Stens 238-037 replacement belt fits Toro models 1578, 1583, 20-7159, 2538589, 6-8850 and 7-0355. It is designed for lawn and garden equipment requiring a durable drive belt. The transparent colour allows visual inspection of the belt condition.

Easy Installation With Aramid Cord

Installation follows the standard belt routing for the listed Toro models. The inner Aramid cord provides exceptional strength and resists heat, abrasion and fraying during operation. Neoprene layers enhance flexibility and resist stretching that can cause loosening over time. No special tools are required beyond those normally used for deck belt replacement.

Check Model Number And Proposition 65

Verify the exact model number of your Toro unit against the compatibility list before ordering. This product carries California Proposition 65 warnings for chemicals known to cause cancer and birth defects or other reproductive harm. Ensure the belt dimensions match the original equipment specifications for your specific mower deck.

Questions about this item

How can I confirm the Stens 238-037 belt is tensioned correctly after fitting it to my Toro 1578?

Press the belt midway between the pulleys; it should deflect roughly half an inch with firm thumb pressure and show no slack when the engine engages the drive.

What does the Stens 238-037 package contain for my Toro 1583 repair?

The box holds one True Blue replacement belt with Aramid cord core and neoprene layers; no pulleys, tensioners or installation tools are included.

Which Stens belt matches Toro part numbers 20-7159 and 2538589?

The Stens 238-037 cross-references both 20-7159 and 2538589, so this single version fits either Toro specification.
