What It Is

This electric PTO (Power Take-Off) clutch engages and disengages the mower blades on select Cub Cadet, MTD, Troy-Bilt, Craftsman, White Outdoor, and Huskee lawn tractors. It replaces OEM part numbers 717-04552, 917-04552, and their variants, plus Warner equivalents 5219-25, 5219-98, and 5219-64.

Fitment & Compatibility

Before buying, verify these three things:

• Model number match: Check your tractor’s model number (not just brand). This clutch fits many but not all MTD-built machines. Cross-reference your OEM part number against the list (717-04552, 917-04552, etc.).
• Physical measurements: Confirm the clutch has a 1-inch bore shaft, 3-bolt mounting pattern, and overall diameter of roughly 4.5 inches. Measure your old clutch’s height (typically 2.5–3 inches).
• Wiring: It uses a two-wire connector (usually flat spade terminals). Ensure your harness matches—some older models may need a pigtail adapter.

Common compatible decks: 42-inch, 46-inch, and 50-inch fabricated or stamped decks on late-1990s through 2010s models.

Key Things to Know

• Installation difficulty: Moderate. Requires removing the mower deck, belt, and possibly the drive pulley. You’ll need a puller tool (or a bolt and washers) to remove the old clutch from the crankshaft.
• Air gap adjustment: After installation, check the air gap between the armature and rotor (typically 0.010–0.015 inches). Too wide = no engagement; too narrow = drag or overheating.
• Quality note: This is an aftermarket replacement, not OEM. It works well for most users, but some report slightly shorter lifespan than genuine Cub Cadet parts (2–3 seasons vs. 3–5). The 4.6-star rating reflects solid value for the price.
• Common gotcha: The wiring harness may be slightly different length or connector angle. Test fit before fully reassembling.

Should You Buy It

Yes, if you need a budget-friendly replacement for a worn-out OEM clutch on a mid-2000s to 2010s MTD tractor and are comfortable with basic mechanical work. Skip it if you want a guaranteed OEM fit or have a newer, high-hour commercial-use machine—spend the extra $50–70 on a genuine Cub Cadet unit for longer reliability.
