Friction clutch for the PTO shaft

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

How does the friction clutch for the PTO shaft 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 next to the driven shaft.
• Compression springs: Press the friction plates together to transmit torque.

Clutch operation:

• Normal Operating Conditions: Under normal operating conditions, the springs press the friction discs together with sufficient force to transmit torque from the tractor to the implement without slipping.
• Overload: When the work tool encounters a sudden load or blockage, the torque exceeds what the friction discs can transmit. Then the discs start to slip against 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 you to connect the tractor's PTO shaft with 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 shaft reduction adapter work?

Basic construction:

• Adapter Input: An end that fits onto the tractor's PTO shaft.
• Adapter output: A tip that fits onto the work tool.
• Locking Mechanism: Secures the adapter to the PTO shaft, preventing it from disconnecting during operation.

Adapter functioning:

• Mounting the adapter: The adapter is mounted on the tractor's PTO shaft by inserting and locking the adapter input on the tractor's shaft.
• Connecting the work tool: The work tool is then connected to the output of the adapter, which fits into its shaft end.
• Power transmission: The adapter allows the transfer of torque from the tractor to the work tool, despite the difference in the diameter or type of shaft ends.
