Rotary Electric PTO Clutch for Exmark Lazer Z 103-3245 103-6590 Warner 5218-243 7-1/8" 103-3245, 103-3131.
Restore Maximum Deck Torque & Fast Blade Braking: Heavy-Duty Electric PTO Clutch
Eliminate slipping mower blades, shredded deck belts, blown electrical fuses, burnt wire plugs, and sluggish blade engagement on your commercial zero-turn mower. This Heavy-Duty Commercial Replacement Electric PTO Clutch Assembly is engineered explicitly to replace Exmark & Toro OEM part numbers 103-3245, 103-6590, and 103-3131, as well as Warner models 5218-243, 5218-100 (with pigtail), and 5218-228 (without pigtail) . Running a 52", 60", or 72" commercial deck with an overheated or slipping clutch bogs down your engine in heavy turf, loses blade tip speed, and leaves ragged, uncut grass across commercial properties.
Engineered to commercial turf standards, this clutch features a massive 7-1/8" diameter drive pulley specifically grooved for heavy-duty 5/8" B-section drive belts , providing maximum belt grip and torque transfer without belt slip. The high-output 12V electromagnetic coil is encapsulated in high-dielectric, thermally conductive epoxy to dissipate heat rapidly and prevent electrical shorts during grueling mid-summer operations. Constructed with a 1" precision-machined inner bore for standard commercial engine crankshaft snouts, it incorporates heavy-duty dual-sealed bearings packed with high-temperature synthetic grease, high-tensile stainless steel leaf drive springs, and an included wiring pigtail harness for seamless drop-in installation.
This high-performance replacement assembly directly replaces Exmark / Toro Part Numbers 103-3245, 103-6590, and 103-3131 , as well as Warner 5218-243, 5218-100, and 5218-228 (Electric PTO Clutch Complete / 1" Crankshaft / 7-1/8" Pulley) .
Why This Upgraded Replacement Electric Clutch is the Commercial Choice:
Commercial-Grade 7-1/8" Drive Pulley: Sized for 5/8" B-section industrial V-belts to maximize contact wrap and eliminate belt slip under heavy load.
Thermal-Resistant Encapsulated Coil: High-dielectric epoxy potting withstands continuous commercial engine heat, preventing winding shorts and blown fuses.
High Holding Torque Rating: Delivers superior clamping force across armature and rotor surfaces to maintain high blade-tip speeds in thick, wet grass.
Precision 1.000" Crankshaft Bore: Fits standard 1-inch engine snouts with standard 1/4" keyway alignment for true concentric rotation.
Includes Wiring Pigtail Harness: Fully compatible with both pigtail and direct plug configurations (replaces Warner 5218-100 with pigtail and 5218-228 without pigtail).
Positive Safety Braking: Integrated mechanical brake pads bring spinning high-inertia mower blades to a complete stop promptly upon disengaging the PTO switch.
