The term was "SOD BUSTER" and meant "farmer".  In the urban dictionary of today, "sidebuster" means "busybody".

I don't have the answer but I know the term is sidebuster. On the Rifleman TV show Lucas was  always referred  to as a sidebuster. He didn't have to do anything and it wasn't a referral to his being a rancher. Someone would look at him without knowing anything about him and call him a sidebuster. I don't know what that means or why they would choose that description of him.

maybe it meant a man's homey ; or maybe it meant a man who was bustin' broncs .

I think a sidebuster is like a sidekick,or a friend..>>>>>><<<<<<<<..

I believe a sidebuster is someone who interferes in other people's matters. Matters that don't really concern him or her. Someone that buts in other people's business. 

Do you not mean sod buster=Farmer
