POSFLAG 3-Pack Flat Idler Pulleys for Toro Mowers 132-9420 Replacement — 4.12" OD, Pre‑Greased Double-Sealed Bearings

POSFLAG's 3-pack flat idler pulleys (model 132-9420) are durable replacement pulleys designed to restore belt routing and smooth deck operation on many Toro, eXmark, Lawn Boy and Timecutter mower models.

If your mower deck has developed belt squeal, slipping, or lost tension, worn idler pulleys are a common cause.

Each pulley includes a double-sealed, pre-greased bearing for lower maintenance and longer service life.
