Man of Honour
It's great that it's entertainment and also interesting.
I'm pretty sure most of us here with no experience would be thinking "How can I plough this field quicker & easier?" and then try a new method before realising it's already the best way.
Anyway, "That tractors too big"
Oh and my favourite the line was something like "The BBC wanted us to be as diverse as possible with this series so here at this auction we've got every type of white grey haired 60 year old man there is"
