Presented for the introduction of new developments which are judged to make advances in the operation of agricultural machinery, SAME DEUTZ-FAHR received the awards for the Hydraulic engine brake concept and the Automatic PTO speed change innovations which were introduced at Agritechnica 2013.
The Hydraulic engine brake concept consists in the tractor braking through energy dissipation by means of the hydraulic system. The use of the existing hydraulic system creates a modulated dissipative system, with electronic control and integrated in the vehicle functionalities. It is a simple, reliable and cost effective system that allows the vehicle control to increase during transport use.
The Automatic PTO speed change is a new PTO concept which works in combination with a CVT transmission and is designed to reduce fuel consumption due to an automatic shift from normal to ECO mode. It is a completely automatic system which is able to make these operating changes through the continuous dialogue between engine, transmission and PTO.
imal manoeuvrability during road transport, the ASM function of the electronic control unit selects or deselects four-wheel drive and locks or unlocks the differentials according to speed and steering angle.
The basic hydraulic system includes a 69 l/min or 83 l/min fixed displacement pump (as an option a 120 l/min Load-Sensing pump is available), plus an independent power steering pump. All models are available with four mechanical distributors in the basic version and up to seven electronic distributors in the VRT version. The rear linkage has a lifting capacity of 6,200 kg or 9,200 kg, 3,800 kg or 4,000 kg for the optional front lift.
On request the cab can be fitted with mechanical or pneumatic suspension; the complete package transforms the cab into a workspace of exceptional comfort, also available with a 12.8" touchscreen monitor (i-Monitor 2.0), an Agrosky GPS navigation system and the ComforTip headland management system.
With the introduction of the Spark series, the new Lamborghini range offers advanced technological solutions, comfort and style in the 120 Hp to 190 Hp segment. A great step forward for the raging bull brand.
