Idler Pulley Spindle for Ariens Gravely

Replacement idler pulley spindle assembly with OEM 30138800 for Ariens and Gravely Ikon, ZTX, and ZTXL zero-turn mowers equipped with a 52-inch deck.

Overview

Designed for fleet operators and property caretakers, it helps extend belt life and reduce deck maintenance intervals.

Specs At A Glance

Good To Know

Q: Does this spindle come with the idler pulley already attached? A: Yes, the idler pulley is pre-installed on the spindle assembly, allowing a direct bolt-in replacement without pressing on a pulley.

Q: How can I tell if the idler pulley spindle needs replacement? A: Look for bearing noise, wobble in the pulley, or belt squeal; if the spindle shaft has visible wear or the pulley has play, replacing the assembly prevents belt damage.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
