riding lawn mower?

There's a guy around here that fabricated a custom tie rod end system to bolt three pushmowers together without the handles. He tows them with his ATV. After years like that I think he's finally upgraded to a "real" riding mower.
 
3 push mowers bolted together, unless they are in a V shape then they are going to leave a gap between each mower.
 
They were in a triangle and offset properly for some overlap. Nothing more annoying than turning corners and leaving strips with your triple-gang mower.
