Based on the existing Deutz-Fahr 5D and Same Dorado tractor models from SDF, the manufacturer has added a continuously variable transmission (CVT) option to each of the five-model series ranging from 83 to 107hp.
Built in house by SDF, the CVT is similar to that used in Deutz-Fahr’s smaller 6 Series TTV models, packaged into the compact 5D and Dorado models. As such, the tractors are aimed at yard, orchard and vineyard work.
The transmission is made up of two ranges with a mechanical range change between high and low. But, rather than a stick shift of the previous generation, electro-hydraulic shifting between the ranges is done with the press of a button on the main control joystick. In addition, there are three driving modes; auto, manual and pto, that allow engine speed and forward speed to be altered in different ways, depending on the task.
The company says the transmission has a high mechanical efficiency. In certain applications, power transfer is 100 per cent mechanical. Top speed of 40kph is achieved at 1,730 rpm.
Power for the tractors comes from SDF’s FARMotion engines, with three- and four-cylinder options of 2.9 and 3.8-litre capacities.
The 90 and 100hp versions are available with either engine, whereas the top model Deutz-Fahr 5110.4 TTV and equivalent Same 110.4 Dorado CVT are equipped with the four-cylinder engine which delivers a maximum power of 113hp and maximum torque of 435Nm. There are no differences in the power or torque outputs of either engine in the smallest model, however, the middle model gains a 5-6hp advantage and 39Nm more torque with the larger engine.
Cab is also new, but based heavily on the narrower vineyard models. It has been widened to accommodate the multifunctional armrest needed for the transmission control. The cab is mounted on hydro silent blocks that reduce shocks transmitting through the cab. As an option it can be fitted with category four filtration, for spraying applications. A full suite of precision farming applications can be added, including GPS guidance for manual steering and IsoBus functionality as well as an eight-inch touch screen terminal.
An additional option is the independent suspended front axle that does away with the standard bar axle and uses a wishbone arrangement instead. The company says this allows for more precise control of front mounted implements as the wheels ride over undulations, without oscillating the front linkage and changing the angle of the attachment.
