Popular Ariens PTO Clutch Replacement Paths

Popular Ariens PTO clutch replacement paths include the 00191700 / 191700 PTO clutch, which cross-references Warner 5219-45, and selected commercial Ariens / Gravely clutch paths such as 03789900. Always confirm the original clutch number and physical specs before ordering.

Ariens 00191700 and 191700 PTO Clutch Fitment

Many Ariens Zoom, Zoom XL, Pro-Master 34Z, and HE19P Power Head applications use the 00191700 / 191700 PTO clutch path. This Ariens / Gravely path should be matched by original clutch number, 1-inch bore, 6-inch pulley, CCW rotation, connector style, pulley offset, and anti-rotation setup.

This path should not be treated as the same as a Toro 110-6766 application by model similarity or marketplace cross-listing alone. For expanded fitment details, see the 00191700 PTO clutch replacement guide.

Ariens 03789900 PTO Clutch Fitment

Some Ariens and Gravely commercial mower platforms use the 03789900 PTO clutch path, which may cross-reference Ogura GT1A-AR03 or Rotary 15783. This is a separate commercial clutch path and should not be merged with 00191700 / 191700 unless your original clutch number and physical specs confirm it.

For those applications, use the 03789900 PTO clutch fitment guide to compare OEM numbers, specs, and compatible mower families.

Ariens PTO Clutch Troubleshooting

If your Ariens blades will not engage, click without spinning, or slip under load, check the full deck-drive system before replacing parts. A weak clutch, worn belt, seized idler, dragging spindle, bad wiring connection, or low voltage can all cause similar symptoms.
