Products Description

Lawn Mower Tractor PTO Clutch Toro - 109-9276
In the aftermarket, the parts that earn repeat business are the ones that disappear into the machine and never make themselves noticed again. This electric PTO clutch is built with that goal in mind as a direct replacement for Toro part number 109-9276. Its electromagnetic coil and friction assembly are matched to the original's engagement characteristics, delivering dependable blade control under normal residential use and heavier commercial schedules alike. The mounting points and wiring match the Toro layout so the exchange is a straight swap, and every production batch is tested for coil performance and engagement quality before it ships, with stock maintained for both single repairs and volume orders.

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

Parts Markup Should Work for You
When an OEM 109-9276 carries a heavy dealer premium, the markup either lands on the customer's quote or comes out of your side of the ledger. This clutch is priced to let you hold a fair margin without inflating the ticket, so the customer feels the value and your parts counter still contributes real profit to every job it touches.
A Second Look Is a Second Guess
A clutch that needs coaxing - a tight bolt pattern, a connector that fights back - is a red flag that the next failure is already scheduled. Our unit is machined against the Toro 109-9276 reference geometry and checked across every mounting surface, so the install is one clean pass. The technician closes the hood, the customer takes delivery, and nobody thinks about it again until the next service interval.


The Maintenance You Never Think About
Every clutch replacement is a small disruption - parts, labor, downtime. The best outcome is making that disruption rare. Our friction assembly is built with wear resistance and heat stability in mind, extending service life and stretching the gap between replacements, so the clutch becomes the last thing on your maintenance list instead of the most frequent.
Order When the Season Allows, Not When It Demands
Emergency sourcing during peak weeks costs time and money that nobody budgets for. We keep the 109-9276 stocked through the working season and back it with steady production, so you can order ahead, restock at your own pace, or grab a single unit on short notice - and every lot arrives with functional testing already done..

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.
