505287301 PTO Clutch for Husqvarna RZ, EZ, LSZ & Dixon | Warner 5219-108

Overview

This 505287301 PTO clutch replacement is an aftermarket electric PTO clutch for select Husqvarna RZ, Husqvarna EZ, Husqvarna LSZ, Dixon Ram, and Dixon SpeedZTR zero-turn mower applications.

This clutch replaces Husqvarna / AYP 505287301 and 287301. The direct Warner replacement path is Warner 5219-108, which supersedes legacy Warner 5219-154. Common aftermarket references include Xtreme X0332, Stens 255-835, and Rotary 14841.

This clutch family is also associated with John Deere AM126100 and several legacy Warner references consolidated into the current Xtreme X0327 replacement path.

Built around a 1-inch crankshaft bore, 5-3/8-inch class pulley, and counter-clockwise rotation, this clutch is designed to restore reliable mower deck engagement. The original Warner 5219-108 specification lists a 5.35-inch pulley and 105 lb-ft torque rating, while some upgraded aftermarket replacements measure approximately 5.45 inches and carry a higher torque rating.

Important fitment warning: Match your original clutch number whenever possible. If the number is missing or unreadable, use your mower’s complete model, product, and serial number to verify 505287301 in the official parts diagram before ordering. Do not order by mower series or deck size alone.

FAQ

Does this PTO clutch replace Husqvarna 505287301?

Is Husqvarna 287301 the same replacement path?

Yes. 287301 is commonly listed as an alternate or shortened reference in the same replacement family as 505287301.

Is Warner 5219-108 the correct cross-reference?

Yes. Warner 5219-108 is the confirmed Warner clutch associated with manufacturer part number 505287301.

Does Warner 5219-108 replace 5219-154?

Yes. Warner identifies 5219-108 as the replacement for legacy 5219-154.

Is this the same replacement family as John Deere AM126100?

Yes. Current aftermarket catalogs consolidate Husqvarna 505287301 and John Deere AM126100 into the same replacement family. For John Deere-specific model information, see the AM126100 PTO clutch replacement page.

Why are both Xtreme X0327 and X0332 listed?

Xtreme X0332 is commonly tied directly to the Husqvarna 505287301 / Warner 5219-108 path. Xtreme’s current X0327 replacement data consolidates 505287301, AM126100, and several legacy Warner clutch numbers into one replacement family.

Does this fit Husqvarna RZ4219 mowers?

Yes. Husqvarna parts information identifies 505287301 for supported RZ4219 applications. Verify your complete product and serial number before ordering because production configurations can change.

Does this fit every Husqvarna RZ, EZ, or LSZ mower?

No. Husqvarna used different PTO clutches within these mower families. Match the original clutch number or verify 505287301 in the model-specific parts diagram rather than ordering by series name or deck size alone.

Does this fit Dixon Ram or SpeedZTR mowers?

This clutch is cataloged for select Dixon Ram and SpeedZTR applications using 287301 or 505287301. Confirm your mower model, production year, and original clutch number before ordering.

What bore size does this clutch use?

This clutch uses a 1-inch crankshaft bore. It will not fit a 1-1/8-inch crankshaft.

What pulley diameter does this clutch use?

This is a 5-3/8-inch class pulley. The original Warner 5219-108 reference lists 5.35 inches, while some upgraded aftermarket replacements measure approximately 5.45 inches. This small catalog difference does not make it a 6-inch clutch path.

What rotation does this clutch use?

This clutch uses counter-clockwise rotation, commonly written as CCW, when viewed from the pulley side.

What should I check before installing the replacement?

Inspect the crankshaft, D-drive or keyway, mounting bolt, anti-rotation stop, deck belt, idlers, blade spindles, PTO switch, battery voltage, wiring connector, and mower-side harness. A damaged mounting stop, weak electrical connection, or dragging deck component can destroy a new clutch quickly.

Can PTO Direct USA help confirm fitment?

Yes. Email support@ptodirectusa.com with your mower model number, product number, serial number, deck size, original clutch number, and clear photos of the old clutch. Include photos of the clutch label, pulley, bore, connector, anti-rotation setup, and mower identification tag.
