John Deere X310 PTO clutch replacement guide for X310 lawn tractors using the AM141536 clutch family.
If your John Deere X310 blades are not engaging, slipping under load, or cutting inconsistently, the PTO clutch is one of the most common failure points.
The X310 commonly uses a 42-inch deck and shares its PTO clutch platform with other X300 Series models, but deck components can vary by configuration.
The correct replacement for most John Deere X310 applications is the AM141536 PTO clutch, which also replaces earlier John Deere OEM numbers including AM134397, AM136787, and AM137323.

Because deck size and configuration can vary, always confirm your deck setup before ordering parts. Worn belts, blades, or spindles can cause slipping, poor cut quality, or inconsistent blade speed that may be mistaken for PTO clutch failure.
Where Is the PTO Clutch on a John Deere X310?
The electric PTO clutch is mounted directly beneath the engine on the crankshaft and sits above the mower deck belt system. It engages the blades when the PTO switch is activated.
Inspection usually requires access from underneath the mower. Safely raising the tractor or removing the deck can make inspection easier.
How to Confirm Fitment
The most reliable way to confirm compatibility is to match the OEM part number stamped on your original PTO clutch.
If the OEM number is worn, missing, or unreadable, use your mower’s model and serial number to verify the correct clutch for your specific configuration.
Because the X310 can use different deck components depending on setup, confirming fitment before ordering is the safest approach.
