CASE IH AND NEW HOLLAND PREMIER

摘要

Both sister brands Case IH and New Holland chose Cereals 2023 as the worldwide debut for their new flagship heavy middleweight prime movers. In the red corner is the Case Optum 340 which, like its blue-painted equivalent, tops out at a maximum engine output of 340hp. (The previous range-topper maxxed out at 313hp). But it's not all about a computergenerated power boost insists CNH. While the muscle is still provided by FPT's time-proven 6.7-litre NEF six-pot, the cylinder head and pistons have been beefed up to deal with the extra stresses generated. Likewise, the cooling pack has been upsized and the hydros and gears in the four range CVX/AutoCommand stepless transmission have been tweaked to deal with the additional load that they'll inevitably come under. It's a similar story with the drivelines to both front and rear pto shafts - extra meat for clutch-packs and gear-sets.
