Description
43590 – SCAG Spindle Bottom Spacer (Genuine OEM Part)
The SCAG 43590 Spindle Bottom Spacer is a genuine OEM replacement component designed to maintain the correct spacing and alignment within the mower deck spindle assembly on compatible SCAG commercial walk-behind mowers. Positioned at the lower portion of the spindle assembly, this precision-machined spacer helps ensure proper bearing preload, blade alignment, and smooth spindle operation.
Manufactured to SCAG’s strict OEM standards, the 43590 spindle bottom spacer is built from durable, high-strength steel to withstand heavy commercial mowing conditions.
