I drive a 2014 Claas Lexion 660 (6 walker). It's got about 1200 hours on it or a little more, I'm in the SE UK.

I've driven several Axial Flows in the 1990's mostly in the US and mostly on the harvest run. I've used the first of the 2388's when they were brand new out.

The farm I work on has had Claas combines for a long time, we've had a 450, 540, 2 550's and this 660. I think it was Dominators before that. This is my 3rd season on the combine here. Our dealer is an hour away if the traffic is good, the traffic is never good here.

The 660 is a big, lump of a machine and after 2388's, you open the side panels and think WTF.

It was a bit of a learning curve for me, partly because I'd not been on a combine from 1998 until 2017 and then switched brands, jumped forward in technology and gone from a rotor to a conventional.

There's been a lot to learn for me, but they've sent me on 2 courses at Claas UK HQ and I've largely got the job sussed now. 

On harvest, we'd swap concaves, grates and sieves at the drop of a hat and it was easy on the 2388's. We don't need to swap them on the Claas because of what we grow, but if we did need to, it's doesn't look an easy job, but I may be wrong.

Other than that, make no mistake, this is a quality product. It gets serviced over winter and aside from 1 sensor on the DPF when it was new it has been utterly reliable. Sorry, just remembered, a steel pipe cracked on the head the first year i had it, but the dealer had us one the following morning.

The farm I work on got sold to the neighbour, they had a 750, but are Deere to the core and it got swapped for a S780i for reasons I'll never understand, mainly because the operator likes dark green paint. I know for a fact it chucked way more field beans on the floor than my Claas did while cutting half the yield.

I suspect Claas have 50% combine market share in the UK and probably cut more than 50% of the crop nationally. For me, an operator, Claas would be my 1st, 2nd, 3rd and 4th choice for a combine. It really is a good machine.
