Drat it, it's a SANDER, not a planer. Gahhh.

One of those days apparently. Sorry about that.

I don't see how it can open to 20" with that plate on the bottom of it. 75 hp seems way off. Most of these go up to 20 hp for each motor/drum.

I concur re looking too small for a 20" opening, but that DOES look about the right size for a 75hp motor.

Now here is an interesting bit of trivia...

To determine the minimum size of the main breaker in your electrical panel, you take your highest motor load, x 1.2, and then double it.

The amp draw for a 75hp 3 phase motor is around 180 amps at 240V. Thus, you'd need a load center rated at 432 amps just in order to start the motor on that planer on 240V 3-phase...

Fortunately, you could cut that in half if you wired it for 480 volts, so you'd only need 216 amps to start it.

Whoa... that's some serious horsepower.
