I've seen this, but it's not that powerful. https://www.amazon.com/910500-Drill-Winch-500lb-capacity/dp/B00SF70SN4
Then there's this attachment to mount medium hitches to hitch ball. https://www.amazon.com/Superwinch-2060-Portable-pattern-capacity/dp/B001Q3E5W4
You could also look at mounting a hook into a hitch mount (http://www.harborfreight.com/automotive-motorcycle/winches/hitch-receiver-mount-for-winches-69106.html) for the winch. I've found that the front hook off of a TJ Wrangler will fit inside the hitch mount. I have no idea what it's rated for, but my limited uses on trailers seems to be fine.
Also, don't use jumper cables... They make quick disconnects for the wiring that would be much safer.
After further deliberation... the hinge thing is probably unnecessary.
A rectangular or square plate is probably superior...

...it could have angle iron "skis" topside to facilitate drag reduction...

...and a 500lb capacity winch to actuate the magnet.

This may be best accomplished by a team of coordinating bots.
A surveying drone...

...a lightweight mine detecting and site marking rover (anything under 50 pounds with a spread footprint I presume to be unlikely to trip a mine)...

...and a heavy duty plate-dropping drone.

To add all functions to one machine is maybe not outside of the realm of possibility. Like this, only much wider and carrying all of the tech listed above.

Requiring a drone capable of lifting 200 pounds or more to sustain flight a few inches above the ground while performing metal detection seems in-viable. Perhaps a guiding contact wire instead of an altimeter could replace the rover, and add its responsibility to the drone.... or function similar to a hovercraft. Surely a drone carrying all of the equipment above is liable to weigh more than 50 pounds... and thus the thrust necessary to lift it may very well be transferred into dangerous pressures on the ground within a few inches of altitude.
Winch 10 pounds
Magnet 2 pounds
Metal detector ~5 pounds?
Survey equipment ~10 pounds?
Drone ??? pounds?
