604713K PTO Clutch Replacement for Hustler Raptor SD & SDX | Replaces 604713, Warner 5219-164

Overview

This aftermarket 604713K PTO clutch replacement is designed for select Hustler Raptor SD and Raptor SDX zero-turn mowers using the 604713, 604713K, or Warner 5219-164 clutch path.

The multi-fit replacement system used in this listing also covers select Hustler Sport, FasTrak, TrimStar, and Big Dog applications using 601784, 601784K, or Warner 5219-107. These are separate OEM clutch-number paths that share the critical dimensions accommodated by this replacement system.

Both available configurations use a 1-inch crankshaft bore, 6-inch pulley, counter-clockwise rotation, and an A/B-section pulley compatible with the mower’s specified 1/2-inch or 5/8-inch belt.

The Standard Black Pulley version provides the most flexible wiring arrangement, with a flat side-by-side connection at the clutch and an included lead for T-style connector applications. The HD Upgrade adds a larger-bearing clutch construction and a short wire lead terminating in a T-style connector.

Choose Your Clutch Configuration

Standard Black Pulley

The Standard Black Pulley version provides the most flexible connector arrangement. A flat side-by-side mower connection can plug directly into the clutch, or the included wire lead can be used on compatible applications requiring a T-style connector.

HD Big Bearing T-Plug Upgrade

The HD Upgrade uses a larger-bearing clutch construction plus an enhanced torque rating intended for demanding mowing conditions. Its short wire lead terminates in a T-style connector for compatible Hustler and Big Dog mower harnesses.

Connector note: Compare the selected variant’s connector with the mower-side harness before installation. Some Hustler configurations use a separate 791251 clutch pigtail. Do not cut or modify either harness until fitment has been confirmed.

FAQ

Does this PTO clutch replace Hustler 604713K?

Yes. This aftermarket clutch replaces the 604713 and 604713K clutch path on compatible Hustler Raptor SD and Raptor SDX applications. Confirm the mower’s serial range because later production commonly uses 605777K instead.

What Warner clutch crosses to Hustler 604713K?

The primary Warner cross-reference for Hustler 604713 and 604713K is Warner 5219-164.

Does this clutch also replace Hustler 601784?

Yes. The multi-fit replacement sold on this page also accommodates select applications using Hustler 601784, 601784K, and Warner 5219-107. The 604713K and 601784 numbers remain separate OEM paths even though this aftermarket replacement covers both configurations.

Does this fit every Hustler mower with a Kawasaki FR651V engine?

No. It fits select Hustler Sport applications equipped with the FR651V and other specifically listed configurations. Confirm the six-digit Hustler model number, serial number, and original PTO clutch number before ordering.

Which variant should I choose for a T-style connector?

The Standard Black Pulley version includes a lead for compatible T-style applications and provides the most wiring flexibility. The HD Big Bearing Upgrade has a short lead terminating in a T-style connector. Compare the product images with the mower-side harness before selecting a variant.

Does 604713K include more than the clutch?

The original Hustler 604713K kit designation may include wiring and mounting hardware in addition to the clutch. This aftermarket listing includes only the clutch and accessories shown with the selected variant. Reuse or replace the mower-specific mounting hardware according to the Hustler parts diagram.

What are the primary clutch specifications?

This replacement uses a 1-inch crankshaft bore, an approximately 6-inch pulley, 12 VDC operation, and counter-clockwise rotation viewed from the pulley side.
