Gravely Pro-Stance PTO Clutch Replacement Guide

If you already know your part number, browse our Gravely PTO clutch collection to find a direct replacement for your mower.

If your Gravely Pro-Stance blades are not engaging, slipping under load, or losing cutting power, a worn PTO clutch is one of the most common causes. These stand-on commercial mowers depend on consistent clutch engagement to maintain blade speed in demanding mowing conditions.

This guide covers PTO clutch fitment, common failure syma wasptoms, and how to identify the correct replacement for Gravely Pro-Stance mower applications.

Gravely Pro-Stance PTO Clutch Replacement

The PTO clutch on Gravely Pro-Stance models mounts directly to the engine crankshaft and engages the mower deck belt system when the PTO switch is activated. This electromagnetic clutch must engage cleanly and consistently to handle frequent engagement cycles typical in commercial use.

As the clutch wears, internal components such as bearings and friction surfaces degrade, leading to slipping, overheating, or complete failure to engage.

Many Gravely Pro-Stance models use the PTO clutch 00191700 that falls within the same cross-reference group as our multi-fit 110-6766 PTO clutch. This clutch platform is also widely used across Ariens, Cub Cadet, Toro, and Exmark mower systems.

Because Gravely and Ariens share platform architecture, Pro-Stance models often use PTO clutch systems similar to those found on Ariens stand-on and commercial equipment.

This clutch also cross-references with OEM numbers including 100-6059, 103-9950, 108-9510, 5219-81, 5219-45, and 5219-34A.

Common Signs of a Failing PTO Clutch on Pro-Stance Models

  • Blades will not engage when the PTO switch is activated
  • Intermittent engagement during operation
  • Loss of blade speed under load
  • Burning smell or overheating near the clutch assembly
  • Squealing or grinding noise from worn bearings
  • Visible wear or heat damage on the clutch housing

Where Is the PTO Clutch Located?

The PTO clutch is mounted beneath the engine crankshaft and sits above the mower deck pulley system. It transfers engine power to the blades when engaged.

Inspection typically requires lifting the unit or accessing the underside of the mower to view the clutch assembly.

How to Confirm the Correct PTO Clutch

The most reliable way to identify the correct replacement is to match the OEM part number stamped on your original clutch.

If your clutch matches any of the cross-reference numbers listed above, this is the correct replacement group to verify.

If the OEM number is not readable, confirm compatibility using mower specifications such as pulley size, crankshaft diameter, and electrical connector type.
