That tiller (if that's the correct term) in the back is a farming tool meant to break ground for seeds, it's the modified snow plow at the front which is meant to clean mines. As it's got pretty much the whole tractor keeping it on the ground it most definetly has enough pressure to trigger mines, the rollers might not take more than one direct hit, but they seem to be relatively simple to replace.

Personally I'd go after something which military uses instead of rollers, where it has motors to spin chains which then detonate the mines, but that's a bit more complex to build and you need more parts than a few bearings and a grinder+welder, so that might not been an option for the guy who built the thing.

Yeah, I've always just heard it referred to colloquially as a "disc", and you use it to "disc a field". In some cases this is a common second step after a first step that plows much, much more aggressively and deeply. I don't know what kind of soil that is and what he plants though, so that first step might be unnecessary.

I don't think it'd be wise to prepare the field for planting and clear the field of mines in the same step, though, at any rate. It would be extremely inappropriate to feel confident that a single pass of your implement has successfully cleared every last mine. When its life on the line, you want near-certainty.

So, he's gonna go over his field with that thing many, many times, not just one. If he's smart. Which means the disc is for mines, not to prepare the field for crops.

My thinking anyway, I don't actually know anything about mine clearing. I do know some about farming though.

I'm in a very same boat, I've been sitting my share on a tractor cabin turning ground around and smoothing it, but our fields don't luckily (now, at 1940s it might've been a bit different at the eastern border) have mines to worry about.
