I am looking for a super-wide plant drill bit, hopefully a minimum of five
inches wide. Here is one that is 2.75 inch wide:

Does anyone know of an ultra-wide drill bit?

Assuming you are planting trees or posts you need a post-hole digger or
augur. The bigger it is the harder it is to turn, the area increases as the
square of the diameter. So a five inch is more than three times the work of
the one illustrated not less than twice.

For a long row these are heavy duty gear power gear often implemented as an
attachment on a tractor or a specialised machine. The reason is that the
amount of torque required to turn the bit turns the operator the same amount
in the opposite direction. If hand held and you strike heavy soil or a tree
root you will turn rather than a large bit.

For just a few holes there is a hand-turned type of augur with horizontal
handles that you and a mate push round but you still have to get the dirt
out of the hole, it won't obligingly spew out like sawdust from a power bit
in softwood. Or get a post-hole shovel. Some are just a narrow blade on a
long handle some are like narrow pincers where you grab a chunk of dirt
between them.
