Coupler for drive lines

A method of assembling a driveline coupler, said method comprising:

• the step of providing a driveline coupler for an irrigation system comprising:
• a gearbox member having a first gearbox member end configured to connect to a shaft of a gearbox or motor, said gearbox member having a second gearbox member end comprising at least two opposing gearbox member puck arms;
• a driveline member having a first driveline member end configured to connect to a driveshaft, said driveline member having a second driveline member end comprising at least two opposing driveline member puck arms;
• wherein said driveline member puck arms and said gearbox member puck arms are configured to be positioned together in an alternating relationship to define a puck void, wherein said driveline member puck arms and said gearbox member puck arms are configured to be positioned together in an alternating relationship to define a puck void proximal to the ends of said driveline member puck arms and said gearbox member puck arms, wherein the distance between said driveline member puck arms at a distal end of said driveline member puck ends is less than at said puck void, wherein the distance between said gearbox members puck arms is narrower than at said puck void;
• the step of providing a puck, said puck comprising a puck center body having a diameter wider than the distance between said ends of said driveline member puck arms and the distance between said ends of said gearbox member puck arms, said puck comprising and at least four spaced apart puck lobes extending outward from said puck center body;
• and
• the step of press fitting the puck body into the puck void, said step comprising the step of press fitting said puck body between said ends of said driveline member puck arms and said ends of said gearbox member puck arms such that one of said lobes is positioned between each gearbox member arm and each driveline member arm and said puck body is positioned in said puck void.
