Friction clutch for PTO shaft

This is a safety mechanism used in agricultural machinery. Its main purpose is to protect against overloads through controlled slippage of friction elements, which prevents damage to machinery and the tractor.

How does a PTO friction clutch work?

Basic construction:

• Friction discs: consists of several discs made of friction material. They can be arranged alternately, one disc is connected to the drive shaft and the other to the driven shaft.
• Compression springs: press the friction plates together, ensuring torque transfer.

Clutch operation:

• Normal operating conditions: Under normal operating conditions, the springs press the friction plates together with sufficient force to transmit torque from the tractor to the working implement without slipping.
• Overload: When the working tool encounters a sudden load or blockage, the torque exceeds the value that the friction plates can transmit. Then the plates begin to slip relative to each other, which reduces the transmitted torque and protects against damage to the mechanism.

PTO shaft reduction adapter

This is a device used in agricultural and gardening machines that allows the tractor's PTO shaft to be connected to a working tool with a different diameter or type of shaft end. These types of adapters are extremely useful when you need to use different machines with one tractor that has an incompatible PTO shaft.

How does the PTO reduction adapter work?

Basic construction:

• Adapter Input: The end that fits onto the tractor PTO shaft.
• Adapter output: The end that fits into the working tool.
• Locking mechanism: secures the adapter to the PTO shaft, preventing it from disconnecting during operation.

Adapter operation:

• Mounting the adapter: The adapter is mounted onto the tractor PTO shaft by inserting and locking the adapter input onto the tractor shaft.
• Connecting the working tool: The working tool is then connected to the adapter output that fits onto its shaft end.
• Power transfer: the adapter enables torque to be transferred from the tractor to the working tool, despite differences in diameter or type of shaft ends.
