One of the farms I worked on in the late 70's had a Lambourn cabbed version, can't say it was my favourite place to spend the day, noisy and draughty springs to mind. Other than that I quite liked the 165's, easy to drive and well set out. I always found the tractormeter to be a bit inaccurate though, I never quite trusted the speed ratings.
I used one on a sprayer for a while and you had to set the sprayer pressure and the forward speed of the tractor to get the right application rates, I always ran out of spray before the end of the field \ \ :( :(
