Looks like the tractor is the attachment. Great find.
Israel has always been great at adapting almost anything.
Back in the 60's when they got F4's from us, the first thing they did was put rearview mirrors in them so that pilots could easily see what was behind them.
Our pilots had to put them in themselves, because the US bureaucracy in its infinite wisdom had hire someone to do a lot of research and get it all approved up the chain and then go out for bids and get them approved before something so simple which saved lives could be done.
