What It Is

This is an electric PTO (power take-off) clutch replacement that engages and disengages the mower blades via an electromagnetic coil. It’s designed for zero-turn and riding mowers from Ariens, Gravely, Husqvarna, Craftsman, AYP, and Poulan Pro, typically with 42–48-inch decks.

Fitment & Compatibility

Before buying, verify your mower’s model number and deck size. This clutch replaces OEM part numbers: Ariens/Gravely 4387900, Husqvarna 587241601 / 400008 / 532400008, Craftsman 179334 / 414336 / 532179334, and AYP/Poulan Ogura GT1A-EH07. It fits Husqvarna EZ 4220, 4624, 4822, 4824 and similar zero-turns. Measure your old clutch: shaft diameter (typically 1 inch), bolt pattern (3-bolt or 4-bolt), and overall thickness. This unit uses a 3-bolt pattern. Confirm your deck wiring harness matches the two-pin connector style. Check your mower’s manual or existing clutch for exact OEM numbers—cross-referencing is critical.

Key Things to Know

• Quality vs. OEM: This is an aftermarket replacement, not OEM. Most users report it holds up well for residential use, but commercial operators may prefer OEM for longer life.
• Installation difficulty: Moderate. You’ll need basic tools (wrenches, multimeter), and you must properly gap the clutch to the engine shaft (typically 0.010–0.020 inches). If you’re not comfortable with electrical testing or belt routing, hire a small engine mechanic.
• Common gotcha: The clutch may come with a slightly different pulley diameter than your original. Measure your belt width and pulley groove to avoid belt slip or noise. Also, check that the wiring connector polarity matches (some machines reverse polarity on the clutch coil).
• Noise note: A few users report a slight whine or click during engagement; this is normal for aftermarket clutches but can be annoying.

Should You Buy It

If you have a compatible Ariens, Gravely, Husqvarna, or Craftsman zero-turn mower (42–48-inch deck) and need a budget-friendly replacement for a failed OEM clutch, this is a solid choice. It’s best for residential owners who want to save money and are comfortable with a DIY install. Skip it if you need a commercial-grade part or have a non-standard deck size—stick with OEM for guaranteed fit and durability.
