Cases Mammoth packs in more power

THE Mammoth 8790 that heads the Case-IH self-propelled forager line also made its working debut at the National Forage Maize event, having earlier this year secured its first contractor customer.

Compared with the Mengele-developed models that make up the rest of the range, the 8790 packs a lot more power – 544hp from a Mercedes-Benz V8 – an uprated driveline, and easier switching from grass to maize specification.

"Unlike designs where the corn cracking rollers have to be mechanically repositioned in the machine, on the Mammoth it simply involves flicking a switch in the cab," says Case-IH area service manager Nigel Worthington. Operating the switch moves panels in the chopping cylinder housing which send grass straight to the blower or maize via the corn cracking rollers. "The Mammoth also has the advantage of having three rather than just two rollers, so there is a greater surface area and more scope for adjustments to get the best balance between throughput and grain cracking," says Mr Worthington.

Other features include hydraulic drive to the feed rollers, giving infinitely adjustable chop length and smooth reversing to eject plugs, and straight power band drive from the transverse-mounted engine to the blower and cutting cylinder.

Knife sharpening and shear adjustment is performed from the cab, and access to the knives is gained by folding the feed roll assembly forwards, then jacking it back into position using a built hand hydraulic pump. The same approach can be used to expose the corn-cracking rollers for inspection. &#42

Changing from grass to maize harvesting set-up involves no more than flicking a switch on the Case-IH Mammoth 8790. Doing so moves chopping cylinder housing panels to divert maize into the three corn cracking rollers.
