Because a side throw leaves clumps of clippings all over your lawn.
A catcher model is hard work when dealing with a lawn that hasn't been cut in months and the grass is two feet tall.
I sure got a workout with my Victa Mustang V40 on some guy's modest sized front lawn in such conditions. The end result blew him away though. He was seriously impressed at how my mower transformed it!
I had to turn him down to do his large back yard full of chest high lawn though!
