Products Description
Lawn Mower Tractor PTO Clutch Exmark Toro- 116-1947
This is a heavy-duty aftermarket electromagnetic PTO clutch engineered as a direct replacement for select Exmark Lazer Z Series and compatible Toro Z Master commercial zero-turn mowers. It is designed for professional landscape contractors, municipal maintenance teams, and large-property service operators who require reliable blade engagement during extended commercial mowing operations.
Unlike many general-replacement clutches built only for standard-duty use, this unit is engineered to handle the specific stress conditions found on high-volume commercial mowers. Long working hours, repeated PTO cycling, heavy grass loads, and exposure to dirt and moisture can create extreme thermal and mechanical strain inside the cutting deck area. Lower-quality clutches in this environment often experience slower blade response, reduced holding force, excessive bearing noise, and unexpected disengagement before the job is complete.
This clutch is built around a 1.125-inch crankshaft bore and counter-clockwise rotation, with a 7.22-inch pulley designed to work with 1/2-inch and 5/8-inch V-belts. It delivers a rated 205 ft-lbs of holding torque, with support for a maximum engine speed of 3600 RPM. The mounting hole pattern, flange dimensions, and electrical connector layout are manufactured to match original-equipment specifications, allowing service technicians to install the unit using standard hand tools. No drilling, grinding, or custom spacers are required for field installation.
To withstand commercial operating conditions, the clutch uses multi-lip composite seals that help keep abrasive turf particles, grass debris, and moisture away from the internal bearing and friction components. The coil structure is optimized for improved heat dissipation, reducing the impact of repeated engage-and-disengage cycles during long mowing shifts. Its thermal capability reaches up to 370°F (188°C), making it better suited to sustained high-heat deck environments.
Every clutch is factory pre-calibrated for proper air gap before packing. It also undergoes coil dielectric testing and static torque retention verification to help ensure consistent performance after installation. This replacement is suitable for individual fleet unit repairs, professional service shop installations, and bulk inventory supply for distributors supporting Exmark and Toro commercial zero-turn maintenance operations.

Products Advantages
What Makes This Serial‑Bound Heavy‑Duty PTO Clutch Stand Out Against Budget‑Market Counterparts?
Our Solution:
Built for Commercial Zero-Turn Operating Conditions
Commercial zero-turn mowers used for large-area maintenance are exposed to constant heat, dirt, and grass debris. The oversized cutting deck area can trap significant thermal energy during long shifts, while fine abrasive particles continually contact the clutch housing. This replacement clutch uses a reinforced friction system designed to maintain stable clamping force through thousands of PTO cycles. Multi-layer composite seals reduce the chance of dirt and moisture entering the bearing and friction assembly, helping the unit hold up better under real commercial use.
Single SKU Covers Multiple OEM Part Numbers
This one aftermarket SKU cross-references multiple Exmark, Toro, and Warner part numbers, including 109-9282, 116-1604, 116-1620, and 5218-207. It is designed with the core physical dimensions required for compatible units: 1.125-inch crankshaft bore, 7.22-inch pulley, and counter-clockwise rotation. For inventory management, this means one part can support repair demand across several compatible models, reducing the need to stock multiple similar clutches. Buyers must still confirm the machine serial number and original part data before ordering.
Reliable 205 Ft-Lbs Torque Under Variable Loads
Commercial mowing is not a steady-load operation. Thick grass, uneven terrain, and multiple properties in one day create sudden torque spikes and constant PTO cycling. This clutch delivers 205 ft-lbs of holding torque and is engineered to maintain more consistent blade speed under changing cutting conditions. The heat-optimized coil helps manage thermal stress, while the friction compound resists glazing and torque fade. This combination can help reduce shock to related components such as deck spindles, drive belts, and the engine crankshaft.
Field-Friendly Installation and Service Planning
Service technicians can install this clutch with standard hand tools because the mounting structure and electrical connection match the original equipment layout. The air gap is pre-calibrated at the factory, so no manual adjustment is needed during installation. For distributors, the clutch is available under a structured supply arrangement with 30-day lead time depending on order volume, making it easier to plan for seasonal demand and emergency restocks during peak mowing months.

FAQ
Q: What information do I need to check before buying this clutch?
A:Start with three things: your full machine model, serial number, and original clutch part number. This clutch fits select Exmark Lazer Z S-Series, E-Series, X-Series, and compatible Toro Z Master G3 zero-turn mowers, but only within the approved serial ranges. It cross-references Exmark 109-9282, 116-1604, 116-1620, Toro 109-9282, 116-1604, 116-1620, and Warner 5218-207. Core specifications include a 1.125-inch crankshaft bore, counter-clockwise rotation, 7.22-inch pulley, support for 1/2-inch and 5/8-inch V-belts, and 205 ft-lbs holding torque.
Q: Why is the serial number so important for this clutch?
A: Because Exmark and Toro made hardware changes across different production batches. Even if the machine looks like a compatible model, units outside the approved serial range may use a different mounting design or crankshaft specification. Installing the wrong unit can cause installation failure, poor performance, or early part damage. Always confirm the serial number before purchase.
Q: Can I install this clutch myself, or do I need special tools?
A:This is a direct-fit replacement, so installation is intended for standard service procedures. It matches the original mounting layout and electrical connector, and the air gap is pre-calibrated at the factory. Most professional technicians can install it using standard hand tools. Always follow the machine service manual and verify fitment before beginning installation.
Q:How can I extend the life of this clutch?
A: Clean the clutch housing and pulley area regularly with compressed air to remove grass and dirt. Inspect the wiring harness and connector for damage, oil exposure, or loose connections. Avoid operating the PTO under prolonged partial slip when cutting extremely heavy grass, and stop operation if you notice unusual noise or performance loss.
|
Q: Is this clutch covered after installation? A: This clutch is manufactured under controlled quality procedures and tested before shipment. Warranty support is provided through the sales channel according to the applicable warranty terms. If you experience an issue, contact your supplier with your machine model, serial number, original part information, and evidence of the problem. |
