Hi Dak, heres my thoughts, remember they are mine and WILL be different to other peoples......im not here to start a colour war, its just what ive found.
ive done a few hundred hours in it, and or running/supervising it for my client. I cant say im overly impressed with it in the conditions weve been in, it continues to run hot, after removing and cleaning radiator, replacing fan pulleys, belt, cleaning screen brushes etc, and dealers involvement. weve found it very hard to keep sample acceptable(clean) without overloading and choking returns/repeats, it is easy to adjust, once I got head around the monitor in cab it was good,simple enough to use.i don't go much on the "ping" noise for everything though, that gets annoying very quickly. I haven't seen anything remarkable in tons/hr like plenty of people promised me it would be capable of, just runs out if power above 11km, and when in dryland, dessicated sorghum of about 2t/ha (12m front) this doesn't seem a huge capacity. I know the crop has limited us here, but really in good dessicated sorghum any header can perform above and beyond, so its good to have a play with it in other conditions.
I find in dry conditions the cab vibrates a lot, cab is very quiet, the top of grain bin extensions and bubble up auger move around a huge amount, must be some wear there in time, folding lids are a nice touch, easy and quick to do,it only has a jd atu for auto steer, this was sub par for gps these days, ive heard very good reports from owners with intergrated steering or machines with jd valve block(or how ever they do it to adapt jd and claas together-I certainly don't blame this machines steering on claas. turning circle is terrible, working in row crop, have to reverse up most ends to get to turn before a ditch/bank.
I find the two fuel tank fills is a pain, as you move from one fill spout to the next any fuel that drips onto engine bay area makes it incredibly slippery to stand on. ladder to cab is an awkward enough beast, steep, handrails don't flow from one to the next, step really reminds me of a 1970s vintage claas my father had when I was younger. to get to radiator to blow it out its pretty narrow and high up( as opposed to the jd where you stand 'inside' the panel work.
the straw chopper wont throw more than 1m past out side of tracks, and due to "speading" mechanism behind chopper it doesn't leave straw evenly spread, instead a pattern is seen where about every 10-15ft (depending on travel speed) lumps of straw are dumped at edge of chopper range. id hate to see how many moving parts there need to be replaced with a few hours on it on this constantly moving what ever its called....
its got a honey bee front on it, nice simple front, for 1200sep hrs seems to have quite a bit of wear in bits and pieces, but I don't know how much maintainence its seem in the past, I do like a front that isn't overly complicated with sensors etc like my 640 is, we run on virtually flat ground and don't need a lot of the crap the deere front is standard with.
for our conditions, given resale values, the dealer service versus the service from our jd dealer I wont be changing anytime soon, but that's just me.
and now due to the slow progress of the crop as we go into winter they are getting me to bring in my s680, so ill get another head full of ideas I guess.
so now let the bagging me out begin........
