Well, you simply have to use them as intended. You go 'round obstacles
from the non-discharge side, obviously.

Two rounds clockwise clears the bagger discharge/chute from obstructions
such as fences/hedges/house, whatever; then lay out the lands as
appropriate for counter-clockwise mowing.

Excess stuff in the way of mowing needs fixing, anyway, bagger or not.

The groves and orchards are more important than the mowing ease, so
the layout will not be changed to suit mowing patterns.
When you are mowing 50' X100' it is a lot different than mowing acres
of trees.
