Exmark Phazer PTO Clutch Replacement Guide

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

If your Exmark Phazer blades are not engaging, slipping under load, or cutting inconsistently, a failing PTO clutch is one of the most common causes. These compact zero-turn mowers rely on consistent clutch engagement to maintain cutting performance.

This guide explains PTO clutch symptoms, location, and how to identify the correct replacement for Exmark Phazer mower applications.

Exmark Phazer PTO Clutch Replacement

The PTO clutch on the Exmark Phazer mounts directly to the engine crankshaft and drives the mower deck belt system when the PTO switch is activated. Over time, wear can cause engagement issues, reduced cutting power, or complete failure.

Many Exmark Phazer models use the 110-6766 PTO clutch, which is also widely used across Toro, Ariens, and Gravely mower platforms.

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 Exmark Phazer

  • Blades will not engage when the PTO switch is activated
  • Intermittent blade operation during mowing
  • Burning smell or overheating near the clutch
  • Squealing or grinding noise from worn bearings
  • Blades stop under load in thicker grass
  • Visible wear or heat damage on the clutch housing

If these symptoms appear, replacing the PTO clutch can restore proper blade engagement and cutting performance.

Where Is the PTO Clutch on an Exmark Phazer?

The PTO clutch is mounted directly under the engine crankshaft and sits above the mower deck belt system. It engages the blades when the PTO switch is turned on.

Inspection typically requires access to the underside of the mower. Raising the unit safely or removing the deck will improve visibility for inspection and replacement.

How to Identify the Correct Replacement PTO Clutch

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

Many Exmark Phazer models use the 110-6766 PTO clutch, but always verify your part number before ordering to ensure proper fitment.

You can also reference OEM cross-over pages such as 100-6059 or 5219-81 if your clutch carries an alternate number.
