Wondering why none of the mower manufacturers never came out with a dual side slinger shotgun setup? One chute on the left and one on the right side of the deck. Bring on the tall grass. I bet Something2lookat and a few others on youtube would buy one.
Do you ever mow tall grass ?
Running the mower over your own clippings is the fastest way to overwhelm a deck .
Back in the days before catchers we used to mow a small patch in the middle of the lawn then go to the edges & mow clockwise so all of the clippings would eventually end up in a pile on the section you originally mowed.
After you carted the clippings away you then had to go & recut the last 1/2 to 1/3 because the volume of clippings being shoved around prevented the blades from cutting all of the grass .
The best mowers for rough cutting are the flail mowers that are rear discharge, sort of like a cross between a reel mower & a tiller on steroids.
Second best are the rear discharge with counter rotating blades
