What It Is

This is an aftermarket electric PTO clutch that engages and disengages the mower blades on zero-turn mowers like Exmark Lazer Z, Wright Stander, Toro Z Master, and Sentar models. It replaces OEM part numbers 653048, 653292, 103-0690, 105-3630, 109-2916, 109-9276, 5218-21, and 5218-44.

Fitment & Compatibility

Before buying, verify your mower’s model and deck size. This clutch fits specific Toro Z Master models (Z400, Z441, Z450, Z147, Z150) and Exmark Lazer Z HP, Wright Stander, and Sentar3 units. Measure your existing clutch’s shaft diameter (typically 1" or 1-1/8"), bolt pattern (3-bolt or 4-bolt), and overall height (usually 2.5–3 inches). Cross-reference your OEM part number from the list above—if it’s not there, this clutch may not fit. Also check that your mower has a 12V electrical system (most do) and that the clutch’s amp draw matches your machine’s specs.

Key Things to Know

• Aftermarket quality: This is an aftermarket replacement, not OEM Toro. It may use different bearings or coil insulation. Check reviews for longevity reports—only 4 reviews so far.
• Installation difficulty: Moderate. You’ll need basic tools (wrenches, socket set) and a multimeter to test electrical continuity. Disconnect battery first. Expect 30–60 minutes.
• Common gotchas: The clutch may need a slight air gap adjustment (0.010–0.015") after install. If it fails to engage, check the wiring harness for corrosion or loose connections. Also verify the pulley alignment with your deck belt—misalignment causes premature wear.
• Return policy: Since it’s aftermarket, confirm the seller’s return window and warranty (often 30–90 days). OEM parts typically have longer warranties.

Should You Buy It

Buy this if you need a budget-friendly replacement for a worn or failed PTO clutch on a compatible Exmark, Wright, Sentar, or Toro Z Master and you’re comfortable with DIY installation. It’s a solid value at $113 compared to OEM prices ($200–$400), but the lack of long-term reviews means it’s best for light to moderate use. If you mow commercially or need guaranteed reliability, stick with an OEM clutch.
