On account of their high efficiency, high operating comfort and the favorable costs/benefits relationship, powershift transmissions are still the most important in the tractor sector. In this segment ZF has already set the market benchmarks with the T-7000 Series. The power spectrum and the functionality have
again been expanded with the next generation - the TERRAPOWER.
With a total of eight models, the new TPT range (TERRAPOWER Transaxle) covers a power range from 65 to 320 hp. On the models TPT 16 to TPT 32 the number of powershift stages is increased compared to the T-7000 Series from four to six and therefore offers a 33% greater gear spread in the respective range. The still finer gear gradation of 18% throughout sets a new benchmark, thereby giving the best values in this class. In conjunction with the optimally matched five synchronous ranges there are a total of 30 forward- and reverse gears available. The optional creep gears comprise an additional 24 forward and 12 reverse speeds. The ranges are matched to the typical working applications for a tractor so that the optimum range and the right powershift range are found for any job.
Due to the high final transmission ratio, transport jobs can be carried out with previously unattainable engine speed reductions. For example, 40 km/h at approximately 1,200 rpm or 50 km/h at 1,500 rpm. Also, an end speed of 60 km/h with a reduced engine speed of approximately 1,800 rpm can be obtained. This means that additional fuel can be saved and the noise level reduced. Through the Intelligent Range Shift (IRS) which is optionally available five synchronous gears can be fast and comfortably shifted.
With the smaller models TPT 09 to TPT 14 a four-way powershift is combined with a field/road range and also a four-way synchronous section which can be automated. The modular structure allows the new transaxle to be optimally configured to the relevant customer demands and comfort requirements. In addition, ZF offers the complete electronic control of the transmission system. The tractor driveline can be optimally matched to the needs of our customers with the additional software functions.
A further highlight is the system rear axle TRA (TERRAREAR Axle) which is also used within the TERRAMATIC range. As standard the axle offers a smoothly starting PTO and integrated breaks for which an electro-hydraulic control is optionally offered. The wet multi-disc brake is designed for control by an electrical parking brake. A lubricating oil shut-off ensures optionally the minimum of drag losses, giving optimum driving performance and
reduced fuel consumption during transport jobs. As the first model in the RERRAPOWER range, the TPT 11 is now available from series production.
