Lower-power Vario makes show debut

FENDTS long awaited 700 Vario series made its debut in Bologna last week and presented Eimas visitors with a first glimpse of lower powered versions of its 900 Vario tractors.

The range comprises two models – the 140hp 714 and the 160hp 716. Both are powered by turbocharged and intercooled 6-cylinder Deutz engines which employ four valves (two exhaust and two inlet) for each cylinder. An in-line injection pump unit comprises a series of electronically controlled individual pumps.

But the main feature of the new tractors is Fendts innovative computer controlled Vario transmission, which, through the use of both mechanical and hydrostatic drives, provides stepless gear changes.

Similar in operation to those fitted to the larger 900 series, the version used in the 714 and 716 tractors are smaller and employ only one hydraulic motor rather than the 900s two.

In operation, its capabilities include programmable speed and engine rpm control plus a number of other monitor displayed functions aimed at easing the task of the operator, and improving efficiency.

Built in true Fendt style – few could deny the quality of the build – the front of the tractor bonnet has a distinctive curved screen not unlike those found on some early, memorable car designs.

But beneath this bonnet lies some clever technology. Lifting the front reveals no less than five cooling radiators – water, transmission/hydraulic oil, intercooler, air conditioning and fuel – the latter a method of ensuring cool fuel enters the high pressure injector pumps.

Fendt designers reasoned there was little future in stacking each radiator in front of each other, efficiency would fall and cleaning would be difficult, if at all possible.

Instead, the radiators are placed in a box with each radiator forming one side. At the rear is the water radiator, in front is one for air conditioning and the sides and top are formed by the other three radiators.

With this configuration, it is not hard to see how air drawn in from the sides and front only passes through two radiators, rather than all five. The large volume within the box allows ample room for individual radiators to be cleaned.

Included in the 700 series specification is hydraulic cab and front suspension, the latter employing a long subframe which pivots at a point halfway along the tractor.
