Products Description

Lawn Mower Tractor PTO Clutch Replaces Warner 5218 6This PTO clutch is a direct aftermarket match for Warner 5218-6, the electric blade-engagement unit found on many zero-turn and riding mowers. At its heart is a high-output electromagnetic coil driving a durable friction assembly, giving operators firm, predictable blade control through full working days. Built to the original's mounting pattern and electrical spec, it installs as a straight swap with nothing to modify. Batch-tested for coil integrity and engagement quality, with reliable stock for everything from one-off repairs to distributor programs, it brings original-equipment performance without the original-equipment invoice.Vehicle Compatibility

Products Advantages
Why Choose Our Electric PTO Clutch over Generic Replacements?
Our Solution:

Dealer Markup Drains Job Profit
Repair invoices are where margins live or die, and a dealer-priced original Warner 5218-6 can quietly erase most of your labor profit on a single job. Multiply that across a busy season and the numbers get painful fast. This replacement is built to match the original's fit, ratings and feel - without the dealer markup - so your pricing stays competitive and your gross profit stays healthy.
A Part That Fights Your Technician
A part that fights your technician costs you twice - once at the counter, once in the bay. Poorly made look-alikes routinely arrive with misaligned bolt patterns and off-spec shafts that demand shims, grinding or improvised brackets. This unit is held to Warner 5218-6 dimensions across every critical surface, so it seats correctly the first time and your crew moves on to the next ticket instead of wrestling with a bad fit.


Friction That Gives Up Mid-Cut
When friction material gives up mid-cut, blades slow, grass tears instead of shearing, and belts start shedding - a failure that shows up exactly when customers are watching. Rather than thin plates that soften under load, this clutch pairs a strong coil with a heat-stable friction surface engineered to keep clamping force steady across long, hot operating windows, so cut quality never depends on the weather or the hour of the day.
An Unavailable Part Is an Idle Machine
An unavailable part is an idle machine, and an idle machine is pure cost - no revenue, no billable hours, just a parked tractor and an unhappy owner. With consistent stock and short lead times, we keep the 5218-6 flowing for emergency single orders and structured fleet programs alike, and every lot ships only after passing coil and engagement checks.

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.
