Does this clutch fit Great Dane Chariot or Super Surfer mowers?

Yes, this clutch is commonly associated with select Great Dane Chariot, Chariot LX, Scamper HG, and Super Surfer Series II applications. Great Dane Super Surfer Series II models with Kawasaki Kai engines should be verified carefully before ordering.

Is Warner 5219-4 the same fitment as GDA10017?

Warner 5219-4 is the primary Warner reference commonly associated with the GDA10017 clutch path.

Is Xtreme X0359 the same fitment as GDA10017?

Xtreme X0359 is an aftermarket cross-reference for the GDA10017 PTO clutch family.

What bore size does GDA10017 use?

This clutch uses a 1-inch bore. If your mower has a 1-1/8 inch crankshaft, this clutch will not fit.

What pulley diameter does this clutch use?

This clutch is commonly listed with a 6-inch pulley diameter. Confirm against your original clutch and product photos before ordering.

What rotation does this clutch use?

This clutch uses counter-clockwise rotation. Match rotation to your original clutch before installing a replacement.

Will I need to splice the wiring?

This clutch uses a wire pigtail style lead. Depending on your mower harness, connector adaptation or splicing may be required. Use sealed electrical connections and inspect the mower-side harness for corrosion, heat damage, or loose terminals before installation.

What are common signs of a failing PTO clutch?

Common symptoms include mower blades not engaging, the PTO clutch clicking but the blades not spinning, slipping under load, intermittent blade engagement, a burning smell, or blades slowing down after the mower heats up. A worn coil can work cold, then weaken after 10 to 30 minutes of mowing.

What should I check before installing a new PTO clutch?

Inspect the PTO switch, battery voltage, wiring connector, deck belt, idler pulleys, blade spindles, anti-rotation bracket, and crankshaft condition. A damaged harness, weak electrical supply, seized idler, or dragging spindle can damage a new clutch.
