Automatically drive at the limit
New in the 800 Vario is the load limit automatic, i.e.
automatic maximum output control. The maximum
output control enables load-dependent adjustment of
the travel speed dependent on engine speed. There are
different optimum values that can be set as the load limit
for different types of operations, for example transport
or field operations. The tractor sets the ideal load limit
automatically. Operators therefore do not need to set
the automatic maximum output control when entering
or leaving the field. And the interplay between the
engine and transmission is just right for each operation.
Alternatively, operators can also set the maximum output
control manually.

Automatic Fendt Effi ciency makes saving easy
For years tests have shown that continuously variable
speed adjustment – such as the Vario transmission offers
– brings huge savings potential in time and money. In
the 800 Vario, the continuously variable ML 200 transmission
ensures maximum drive train efficiency. The Tractor
Management System TMS keeps the engine and transmission
in the ideal operating range during all operations
– that means automatic efficiency. Moreover, the drive
train in the rear axle has been developed further: the
slow-running multi-disc brake further reduces fuel consumption
of the already very economical drive train.

The ingenious Fendt Vario transmission
The Fendt Vario transmission is a hydrostatic-mechanical power split drive. With increasing speed, the share of the mechanical
power transmitted through the planetary set increases. The hydrostats, which can be swung 45 degrees, and a high operating
pressure of max. 550 bar ensure exceptional effi ciency.

A new drive train in the rear axle
for the best efficiency
A completely new drive train has
been developed for the rear axle of
the 800 Vario. The new slow-running
brakes minimise losses in the rear
axle. This enables the best effi ciency
and reduces fuel consumption, even
at high speeds, which is particularly
important for transport work.
