4wd Driveshaft Ball (each)

Yanmar Tractor 4wd Driveshaft Ball (each)

These balls act as a type of U-Joint which transfers the 4wd axle power from one shaft to another while allowing a slight change in alignment.  

There are 6 of these used in each coupler end (12 per tractor)

Pro Tip: 
Cover the coupling in grease to hold the balls in place while you are installing them
