On an area of the size of 40 football pitches, this is the biggest monthly second-hand farm machinery auction on earth. It attracts buyers from all over the

world. So how does it feel to be a top auctioneer focusing the world's attention on a mighty machine for sale.

And if you buy a big tractor, then how do you fit it in a shipping container to send it

on its way? I'm Susie Emmett and here on BBC World Service

I'd like you to join me for a day here to follow that

follow that tractor.

So let's meet some buyers to find out what they have on their tractor shopping lists.

My name is Arach, I'm from Poland.

I'm interested, maybe a little bit older

tractor, everything what we can sell in Poland and good price and very quick.

I'm learning now. Last month it was first time and now it's second time we are here to make some

money and no loss of course.

My name is Ali. It's a long journey from East Africa, Kenya to London, Heathrow, then from Heathrow,

higher a car and drive to Cambridge auction. When I started here I started with two tractors but now I have a

capacity of buying 15 to 20 tractors every month and the demand is very high in my country.

So hopefully I can extend even to the neighboring country, Tanzania, Uganda, and South Sudan.

That's my ambitions now.

If you can fail to your people there and grow the economy of the country, the economy of the country really depends on agriculture, that's really my pleasure.

Yeah. That's really my pleasure.

My name's Don Haparachi and I'm today here to buy for Sri Lanka, Thailand, Cyprus, Cyprus, Norway, Denmark, Sweden.

My shopping list today is diggers, small tractors, grass cutting machinery, lifting gear, small trailers, big trailers, plows,

so I'll probably buy stuff but it's not in my list.
