Products Description

Lawn Mower Tractor PTO Clutch Gravely - 00191700This electric PTO clutch is a direct aftermarket replacement for Gravely part number 00191700, engineered for the blade drive systems of Gravely lawn and turf mowers where dependable engagement keeps the working day moving. The unit combines a high-output electromagnetic coil with a friction assembly matched to the original's engagement profile - smooth pickup, steady holding, clean release - so the deck responds exactly as the operator expects. It is manufactured to the 00191700 reference layout: mounting pattern, shaft interface and electrical connection all reproduce the factory part, making the exchange a direct bolt-for-bolt swap with no modification or adapter components. Construction focuses on service life in real conditions: heat-tolerant materials protect the working components under sustained load, sealed internals keep dust and moisture out of the mechanism, and the friction face resists the gradual wear that quietly drains cutting performance. Every batch is tested for coil integrity and engagement consistency before dispatch, and working stock is maintained to support both urgent single-unit repairs and planned fleet or dealer programs.Vehicle Compatibility

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

Every Dollar Overpaid Is a Dollar Unearned
A Gravely in the shop for a clutch isn't earning - and neither is the premium on the factory part that keeps the invoice high. Our 00191700 replacement matches the original's engagement and durability standard at an aftermarket price, so the repair's total cost stays honest, the machine returns to revenue faster, and the savings land in the operating budget where they belong.
The Right Fit Is the Fastest Fit
Time on the lift is the one cost every shop feels twice - once in labor, once in lost machine hours. A part that bolts up without debate keeps both low. This clutch is manufactured against the Gravely 00191700 dimensions and verified across its critical surfaces, so installation runs exactly per the service procedure: remove, seat, connect, confirm. First attempt, done, back to work.


Heat Is Where Cheap Clutches Surrender
Afternoon heat is the enemy of thin friction plates - clamping force fades, blade speed drops, and the cut quality goes with it. Our coil and friction assembly are engineered to hold engagement firm through sustained hot operation and repeated cycles, keeping deck speed stable from the morning's first pass to the evening's last, so the finish never depends on the thermometer.
Supply That Runs Ahead of the Schedule
The difference between a good week and a bad one is often just parts availability. We keep the 00191700 in working stock through the season with continuous production behind it, covering same-week emergencies and planned multi-unit orders on timelines you can schedule around - with functional testing completed on every batch before it ships.

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.
