[QUOTE="hutchy143211, post: 7668273, member: 110394"] Personally love our kuhn 2160 variable chamber, 2014 model done ~17,000 bales. I'll admit I've never used a mchale so can't comment entirely on what their like but have observed a few things looking under the sides. Firstly IMO the kuhn is a far simpler baler mechanically. Looking under the sides of a mchale there's banks of grease nipples, lots of double drive chains and I'd guess a lot more bearings (I.e. stub augers). Our kuhn maybe has 6/7 grease points each side with most easily accessed. It has extra chains as its double drive, with 2 powered rotors as part of the silage kit but still far simpler than our previous roller Greenland or mchales I've seen. We've never had any issues with bales slipping when baling and think this is a big part of it. Secondly, the pickup and feed system. I don't think the kuhn has the greatest pickup real in the world but its certainly good, can't comment on Mchales. However, where the kuhn is better in my opinion is the main feed rotor. Kuhn's is the bombproof vicon opticut system with one solid rotor with flight either side. This is where the kuhn gets its output capacity in dry material and its how fast you want to feed it. Behind a 17ft combine not doing silly speeds 80-90 bales/hour isn't uncommon for us. In grass this also helps as grass doesn't tend to ball under the flighted auger and just feeds as a nice mat. I will admit though we bale drier silage/haylage. The knife system is nice and simple and the drop floor is great if it gets blocked, we've found this a great feature in tough permanent grass which knots. Thirdly, not sure if mchale has changed to it but the isobus controls with the kuhn (option but many are) is absolutely first class. Simple as can be to operate the baler with size and net wrap all touch screen inputs. Ours doesn't but I believe the new ones can even alter the main density setting from there. 40 individual field counters with a main seasonal one gives you the ability to keep individual records with 3 finger taps. Other things with the kuhn as said, density adjustment is great. Main one is a screw valve at the front to adjust pressure (180 bar silage, 200 straw but we do almost everything at 180), new ones I think can be adjusted in cab. You can adjust the core as well from 3 settings but we find the middle standard setting to be perfectly fine. Net wrap system is nice and simple, with steps to aid access and storage for 2 additional rolls under the wings and manual feed options if there issues through the isobus screen. Issues we've had with the baler in this time are: - broken pickup reel chain (baling rigde and furrows) - broken precompression roller suspension spring - broken door latches (crap design) - dolly wheel punctures (fixed so scrub, new ones may caster?) The one big gripe we have with it is the internal scraper on the main drive. PITA to adjust between straw and grass (1mm clearance to scrap silage, 5mm clearance to stop straw pushing through). We switch it 4 times a year roughly and you can do an odd field in the incorrect way. Apparently you can set it at 3mm and do everything but never tried it. Despite this, we love it and would have another tomorrow in a heart beat. Great output, clean stubbles and uniform bales so it seems fine! [/QUOTE]
