cab, CAB, what sort of wooses were you.
cabs came in some time in the sixties for safety reasons, in the UK then 50 odd tractor drivers a year died as a result of overturns or stepping off or onto a moving tractor (yes I've done that a thousand times myself), then sound levels brought in Qcabs, of course if you worked for yourself you could die or become deaf as often as you liked and still be legal but for employed drivers an accident whilst not adhering to HSE laws meant you were on your own afterwards.
My neighbour has just had two hearing aids fitted (ex tractor driver) and I have difficulty hearing my wife at times

.
Sadly the death rate in agriculture remains too high ( 30 deaths a year) in that respect it is the most dangerous occupation in the UK.
Previous to all these changes we bounced up and down on a metal seat bolted to a leaf spring
