Consistent crop flow and higher throughput with new front attachment drives
The most significant new development for the JAGUAR 900 model series is the expansion of the options for the front attachment drive. In addition to the all-mechanical drive and the variable drive for the ORBIS maize front attachments as well as the PICK UP, it is now possible for customers to specify a twin hydraulic drive which offers particular benefits when working with the PICK UP. With this option, the intake auger continues to be driven via the quick-release coupler, and can adjust its speed in accordance with the length of cut; the pick-up reel, however, is provided with an all-new hydraulic drive which allows it to be driven with variable speed adjustment independently of the intake auger. The principal objective of enabling the pick-up reel speed to be varied is to allow it to be adjusted automatically to the ground speed, so the faster the forward speed, so the pickup speed will correspondingly increase. Important advantages associated with this functionality include efficient raking action at all ground speeds with extremely low wear; if the ground speed or the set length of cut is changed, the rotational speeds of the auger and reel are adjusted automatically to the prevailing conditions. If necessary, both speeds can be adjusted to the requirements of the harvesting situation manually by the operator from the cab. It is therefore possible to respond to changing harvesting conditions either automatically or manually from the cab. The result, especially in changing conditions, is even more accurate crop feeding and a more consistent crop flow overall. Studies of large swaths whole crop silage harvesting using the PICK UP conducted in California with a JAGUAR 990 have shown increased throughput levels of up to 13.7% in extreme conditions compared with an all-mechanical constant drive. These major advantages always come into their own when very high yields are harvested at low ground speeds or low yields are harvested at very high ground speeds.
