I agree that the chickens don't care what catcher they lay in. I would like to know where that farmer lives and do just that. He/She must have an enormous number of catchers because this happens about twice a year I think. Maybe more than one farmer doing it as word gets around about how great catchers are for this purpose. They're oblivious to the dogfights the rest of us mower guys get into over the remaing ones, lol.
I might even take a trip to Sarina, about 30k away, and see what's at their tip. That particular catcher for the Rover 45 seems a bit rare. I have bought a couple of rover catchers thinking that's the one for it but they don't fit it.
