Notice that the jack is a side crank,type, which is as readily available as a front crank. The handle was simply removed(not cut) and replaced with a piece of drillrod and a nut(could use a shoulder bolt). This can be done with a hacksaw and a hand drill.
Another choice would be to switch to an electric tongue jack.

Floyd,
Do you have any pictures as to how it is attached to the inside of the jack? I would love to change mine to this type to use with a battery drill.

Below is a photo which I just took showing the jack head with the cover removed.
You can see the ring gear in the base of the gearbox with the pinion gear to the right. On the shoulder of the pinion gear (just to the right of the teeth) is a role-pin. (the little brown thing at the bottom).
You knock out the role-pin, which allows the crankshaft to be extracted. Then you can insert the new shaft, align and drive in the role-pin, add a dab of grease,and reinstall the cover.
Be sure to drill the hole in the new shaft the same size as the original and at the same distance from the tip.

Tongue Jack Crank Modification

Here's what I did...

There's no welding but only drilling. Precise drilling and patience is mandatory.
If you're mechanically incline, you'll find this modification easy-peasy-lemon-squeezy...

I simply welded a 3/4 bolt on the end of the handle shaft. I can use my cordless drill with a 3/4 socket (my stabilizers jacks use the same) or crank it manually.
Just gotta watch for the spinning crank handle when using the drill ;-)
(and yes, I did spray some paint on it once the rain stopped!)
