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.

lower fuel consumption.
