Worked on a farm one summer holiday when at college.
Had contractors in to empty and spread the slurry pit, one of the old boys at the farm used to grow his prize marrows on it, he walked out on this huge hole twenty plus feet deep to plant and harvest! If he had sunk it would have been without a trace!.
Old vs new, the contractors had lovely shiny new tractors and specialised spreading kit, we supplied a drot to load them and an ancient Fordson tractor to drag them up the slippery slope out of the pit.
Preparation on the Fordson
Take its rear wheels off and replace with spade-lug steel wheels
I was given the job of driving it across the yard, found out why on the first foot, lift, drop, thud/clank, lift, drop, thud/clank lift .... (repeat add naseum)

.
Completely un-stoppable though.
"My" tractor was a newer International two wheel drive with diff lock and I (young and foolish) decided to see what it could do when we were finishing off a more solid above ground heap.
Drove it through the heap and out the other side, leaving a tractor shaped hole right the way across.
I got my come-uppance later thought, always drive into the wind when muck-spreading, a 2lB turd in the back of the head hurts

and the little bits get everywhere.
Worst though was when taking the yearly supply of barley straw to the piggery, my hat fell off into the weaners pen.

Twenty little piggies thought this was christmas and here was a great new toy to play hunt the holder with.

Off went my hat in the mouth of piglet-1 with piglets 2 to 20 in hot pursuit. The pigman gave me my hat back twenty minutes later, intact, but with an even coating and a certain eau-de-merde-de-cochon

a go in the washing-machine by itself got rid of the worst and a couple more washes made it wearable, poor student remember.
Piglet, when was your first avatar photo, the one with the lairy grin taken, was it in 1981 as my memory now says that I have seen that grin before, partly obscured by a hat
