Product description

1-1/8" x 6T (female) / 1-3/8" x 6T ( male) PTO/PTO freewheel.

What is a directional clutch?

The clutch is designed to instantly disconnect the transmission shafts to prevent damage or failure of the machine, device or tractor. Overload clutches are present in all branches of industry and differ from each other in the method of assembly and the type of connector and the limit value of the torque, and most importantly, the directional clutch after completing the task (disengagement of the drive after too much load) is not damaged.

The main task of the one-way PTO/PTO overrunning clutch is torque transmission as well as connecting and disconnecting drive shafts. One-way clutch is widely used in agriculture. Machines and devices that use the PTO shaft rotate at very high speeds. For the safety of the machine and the tractor, a PTO/PTO shaft adapter with a clutch is used as protection.

When do we use a one-way clutch?

Japanese tillers of various manufacturers and brands where the adapter can be installed both between the PTO shaft of the tractor or the PTO shaft and the device. During the operation of the device, there may be a change in the direction of rotation or a sudden undesirable stop of the machine, and at this point our clutch disengages and works in idle mode without the need to disengage the PTO shaft drive in the tractor.

Before each use of the adapter, it is recommended to properly lubricate it through the calipers attached to the adapter .

Questions & Answers

Why is regular filter replacement (oil, air, fuel) crucial for a mini tractor?

User
Traktor.com.pl Expert – Technical Advisor • 17.02.2026
Regular filter replacement is the easiest way to extend the life of an engine from brands like Kubota or Yanmar. The oil filter removes metallic contaminants generated during operation, the air filter protects the cylinders from field dust, and the fuel filter prevents water and dirt from damaging the precision injection system. We recommend replacing filters every 50-100 operating hours or at least once per season to ensure optimal engine performance.

What are the benefits of using a transport box on a small farm, and what are their typical capacities?

User

Transport boxes are among the most versatile accessories for mini tractors. On small farms, they allow for the convenient transport of crops, timber, tools, or bulk materials without the need for a trailer. The load capacity of typical boxes ranges from 200 to even 600 kg, depending on the model and tractor power. Thanks to the tipping system (mechanical or hydraulic), unloading is quick and requires little physical effort.

How to properly select and sharpen mower blades for a Japanese tractor?

User
Traktor.com.pl Expert – Technical Advisor • 17.02.2026
When selecting mower blades, consider the mower deck model and the blade length and center bore diameter. Maintaining blade balance is crucial when sharpening – an unbalanced blade causes vibrations that damage the hub bearings. Remember that sharp blades mean healthier grass, a cleaner cut, and less strain on the engine of your Iseki or Mitsubishi tractor.
