in a similar vein - When I drove a Fergie 35 we used to look forward to the smaller tractors job of leading grain from the combines to the drier (early 60s) the Combines were also MF, the driver sat to the left hand side of the combine, below the drivers seat was where the toolbox lived, un beknown to me a favourite trick was to site an oilcan in the toolbox with it's spout sticking out in line with any driver pulling alongside to empty the combines bin, the combine driver just had to move his foot back onto the top of the toolbox and pump it to deliver a scoot of oil onto the driver emptying the bin and yes that's exactly what happened.
I jumped off the 35 not quite managing to select neutral and it took off, being young supply and quite fast I ran after the trailer, climbed up the back of it intent to save the situation by getting back to the tractor seat via the trailer, the tractor meanwhile had found it's way to the edge of the field, crashed/jumped through a hedge headed across the corner of the adjacent field and was heading towards a dean (shallow wooded gully with a stream flowing through it).
I had by this time decided the situation was beyond saving and jumped out of the trailer.
Damage to the tractor was only a bent radius rod, damage to my status was a severe ticking off from the boos at the repair shop and leg pulling for quite some time, but a let off in as much as it's debatable what the outcome would have been if I'd stuck to my plan, and the estate manager got the whole story somehow (not by me) as I got a stern look and nothing else, combine driver possibly got a word or two I don't know
