Claas is known for releasing innovative machinery that adds on to its already impressive range. For 2017, the German company’s plans focus on the popular Jaguar harvester models.
The Claas Jaguar 980 and 970 self-propelled harvesters will be replaced in the New Year by enhanced versions. From 2017 onwards, new equipment features will be available in the harvesters.
Some of the new features include a continuously variable front attachment drive, a further enhanced crop flow system, redesigned running gear and the Claas auto-fill system for loss-free offloading to the side and rear.
Continuously Variable Front Attachment Drive
The hydrostatic drive adjusts front attachment speed automatically, which enables efficient power transmission at varying speeds.
This is particularly advantageous when harvesting with the ‘Pick Up’ and the ‘Orbis’ maize front attachment. If the chop length changes, the system automatically makes a corresponding adjustment to the front attachment speed.
The result is a very even crop flow and consistently good chop quality. Furthermore, the operator can react to changing harvest conditions at any time by manually adjusting the automatically controlled front attachment speed.
The constant-speed mechanical drive which has proven itself over many years of practical use will still be available. The mechanical drive can now also be combined with the continuously variable drive. This split-power variant with mechanical and hydraulic drive provides high power transmission at a constant speed. This allows the direct cutterbar ‘Direct Disc’ and the maize pickers to be driven powerfully and extremely efficiently.
Optimal crop flow through automatically adjusting drum concave
All new Jaguar 900 models also have an enhanced crop flow system. One of its key features is the hydraulic clamping system for the shear bar which allows the shear bar to be adjusted considerably faster than before. Following adjustment, the shear bar is clamped in place hydraulically and remains in the required position reliably. This makes for consistently high chop quality. As before, the operator can control this function from the cab.
The new models also work with an automatically adjustable drum concave. The drum concave is attached directly to the mounting block and another pivot point and is automatically moved with the shear bar when the latter is adjusted.
This means that the distance between the concave and the chopper knives remains constant over the entire length of the drum concave, thereby ensuring an even crop flow, regardless of the condition of the knives. Furthermore, this arrangement saves fuel and reduces wear.
Auto-Fill now also allows offloading to the rear
The Claas Auto-Fill system for offloading to the side during chopping keeps losses to a minimum during the offloading process while also significantly reducing the respective workloads of the operators of the forage transport wagon and the forage harvester. A high-resolution camera on the discharge spout captures the contours of the forage transport wagon continuously during the run and automatically adjusts the crop discharge direction to the contours and the load situation. A new feature is support for offloading to the rear, a function which is used when starting chopping or dividing the areas to be harvested. The enhanced Auto-Fill system provides a considerable reduction in operator workload.
New running gear
The running gear of the new Jaguar 900 models also offers greater comfort and convenience for the operator. The new hydrostatic motor, a variable hydraulic motor with two-position control, has a wide speed range. This enables on-road travel at very low motor revs, which in turn has a positive effect on diesel consumption. Fuel is also saved during harvesting thanks to an automatic motor speed reduction function when turning at the headland.
High tractive power and optimal responsiveness
Operating in the field in first gear, the powerful ground drive allows the machine to run at up to 22 km/h. Furthermore, all the new Jaguar 900 models offer very high tractive power and steady responsiveness, factors which come into their own when the forage harvester is moving off on an uphill slope or accelerating. A differential lock enables optimal traction at all times, even under difficult conditions. It can be controlled either manually, in automatic switch-on mode which is triggered when wheel slip is detected or in automatic switch-off mode when a given steering angle and speeds greater than 15 km/h are attained. Furthermore, all models have a convenient automatic parking brake which is applied when the operator places the control lever in the neutral position.
All Jaguar 900 models are now equipped as standard with the Cruise Pilot forward travel control.
