FAQ
Q: How do I select the correct electric PTO clutch for my specific mower model?
A:To guarantee a 100% exact fit, you need to verify four critical mechanical dimensions:1. Shaft Bore Size: Common sizes are 1" (25.4 mm) or 1-1/8" (28.6 mm).2. Pulley Outer Diameter (OD) & Belt Width: Matches your deck's V-belt size (e.g., 1/2" or 5/8").3. Rotation Direction: Clockwise (CW) or Counter-Clockwise (CCW) when viewing from the pulley end.4. OEM Cross-Reference: Compare with original numbers (Warner, Ogura, John Deere, etc.).If you provide us with your engine model or original part number, our engineering team will cross-check our database and provide a 3D fitment drawing for confirmation.
Q: What measures are taken to prevent the coil from burning out during heavy-duty operation?
A: Our electric PTO clutches are built with Class H insulated copper wire, rated for temperatures up to 180°C (356°F). Combined with dual-sealed C3 high-speed bearings and dynamic balance calibration, our design reduces friction-induced heat, significantly lowering the risk of thermal coil failure under prolonged high-load conditions.
Q: What is your quality inspection protocol before shipment?
A:Every single clutch (100% full inspection, not random sampling) passes through our 4-step automated testing rig before packaging:
1. Coil Resistance & Amperage Test: Verifies electrical integrity.2. Static Torque Capacity Test: Ensures proper torque engagement under load.3. Air Gap Precision Check: Factory preset to optimal clearance (0.012" - 0.020") for immediate response.4. Dynamic Balance & Noise Level Test: Ensures vibration-free operation.
Q: Do you offer custom OEM/ODM development for specialized lawn equipment manufacturers?
A: Yes. We regularly partner with OEM machine builders and private-label brand owners. Our customization capabilities include:Custom Wiring Harnesses: Wire gauge, sleeve protection (corrugated/braided), and waterproof connector types (Deutsch, Molex, Amphenol).Custom Pulley Configurations: Single/double groove, specific ODs, and anti-corrosion plating.Branding & Packaging: Laser-etched logos/part numbers on the steel body, custom color box packaging, and barcoded master cartons.
