Bumping the starter?

This is for my manual persons!
My father brought something up to me this weekend I'd like some input on.
he has a '72 Chevy 4x4 that he used to wheel a bit. When in a sticky situation and alone (no spotter) he says he would shut his truck off, get out and assess. Then climb back in and leave it in 1st and 4lo, and "bump" the starter. Turning the key just enough to allow the starter to move the truck forward inches at a time. Get out and assess again.
My question for y'all is has anyone done this?
How well does it work?
And is it worth ruining a starter instead of something major happening?

Thanks in advance for the input.

I'd like to remind you this technique was only used in desperate situations.

 

I use it when warming up my truck is all!

 

i have never done it personally, but i have seen many people do it, and heard of alot of people doing it. i have the clutch start cancel... might have to try when in a shitty situation..

 

My old bronco didn't have a clutch switch so it could be started without touching the clutch. One time I accidentally had it in first (super low granny gear) and went to start it. It started right up and started rolling forward with no damage, freaked me out though.
So yeah I think it would work but only in an emergency since it can't be good on the starter.

 

I have used it to start after stalling on an obstacle. Bumping is rough on the starter. Better to winch out than not be able to start the truck.
Dire emergency? Yes. Spotting aid? Only if I have a spare starter, lol.
