Well thought out ergonomics and functionality
are essential in the cab of a tractor. The Vario
800 workplace was designed with this in mind.
The functions are convenient and very easy to
understand. Important details that make life eas­ier for the driver are adapted to the challenges
of hard daily operation, and offer comfort for a
long working day.
Maintaining condition and fitness is essential for
the Fendt driver. The intelligent Fendt technol­ogy, which enhances the control processes,
helps meet these demands. That allows the
driver to keep getting the most out of his 800
Vario over a long working day. That makes com­fort an economical factor.

Welcome to the Variotronic World. You work many
hours on a 800 Vario

TMS

– that is why operating
and driving comfort have the highest priority. With
its three elements – a joystick, monitor and con­trol console – the new Variotronic not only ensures
extraordinary working comfort, but also unparal­leled productivity.
With the new Variotronic TIyou can recall previ­ously stored, optimized working processes with a
touch of a key – again and again. For you this
means: ingeniously simple handling – not just
during the test drive. Moreover, you will receive
full benefits in profitability and productivity during
in-field operation.

A NEW WAY TO DRIVE
VARIO DRIVING WITH TMS

Fendt Vario: more comfort and higher productivity

Driving a tractor is certainly more than just sitting
in it and driving away. You know that most of all.
There are different conditions to consider for every
operation you carry out with your tractor. That is the
reason why you should evaluate an operating con­cept based on specific operations. This was the
practical background which was the basis for the
development of the Vario operating concept with the
Tractor Management System Vario

TMS

.
Compared to operating concepts on other tractors
with stepless transmission, the Tractor Manage­ment System Vario

TMS

Vario TMS from Fendt pro­vides very convincing concrete benefits. It allows
you to carry out your work more comfortably and
easily. Beginners find their way around quickly and
easily, and the Vario

TMS

concept offers great poten­tial for professionals. Whether you are a beginner
or pro – Vario

TMS

allows you to do your work more

profitably.

Driving with the joystick

The ingenious control which allows you can carry out all functions
using only your right hand, without having to change grips.
You can accelerate, decelerate and reverse as well as activate the
Tempomat with only a small movement of the joystick. You can oper­ate all other functions, from the easy-to-use PTO automatic mode to
the headland management system, with the ergonomically friendly
multi-function buttons.

TRACTOR MANAGEMENT SYSTEM

When the TMS (Tractor Management System) is activated, the tractor
electronics control the engine and transmission. This significantly
increases operating comfort for the driver. The driver only needs to
set the desired speed; the TMS controls the rest. In the graphic above,
one can recognize that the tractor drives on level ground at a reduced

engine speed. On the slope, the load increases, so the TMS increases
the engine speed. As soon as the load decreases (on level ground or
downhill) the quantity of fuel injected is reduced. This maintains an
economical driving style since TMS drives the tractor at the lowest
engine speed possible.

Driving pedal mode

Set the direction you would like to drive with your left hand, then all
that is needed to start the tractor is to press the driving pedal. In the
driving pedal mode, only the right foot is required to drive the tractor
– similar to a car with an automatic transmission. The further the
pedal is pressed down, the faster the tractor goes. The sliding control
on the armrest sets the maximum speed that is attained when the
pedal is pressed all the way down. If you release the pressure on the
pedal, the 800 Vario

TMS

decelerates.
For an additional engine braking effect, the driver can also
take over control of the TMS in the driving pedal mode and
reduce the transmission ratio manually.

VARIO OPERATION –
EASY AS EVER

Driving forward

Push the joystick for­ward; the Vario accelerates
forward from standstill.

Accelerate forward

Not fast enough? Then
push the joystick forward a
bit longer, until you have reached the
desired speed.

Decelerate

If you are going too fast, pull the joystick
back and the Vario 800 brakes the engine and
transmission.

Reverse

Pull the joystick back and the Vario reverses from standstill. Faster
or slower reverse speeds function in the same way as for forward
travel.

Rapid or slow acceleration

How rapidly or slowly you accelerate or decelerate is determined by
which of the four pre-set acceleration rates you select with the thumb
control.

Automatic forward/reverse

Giving the joystick a quick tap to the left is all that is necessary to
change driving direction from forward to reverse or vice versa. The
Vario decelerates to a standstill by itself and then accelerates, with­out jerking, in the opposite direction.

Tempomat cruise control

The Tempomat holds the tractor at a constant pre-set speed. All that
is required to activate it, is to give the joystick a quick tap to the
right.

NEW: The switch on the
steering column adjustment
lever has three functions:

1. Changing directions while driving.

2. Setting travel direction in the
driving pedal mode.

3. Stop and go function with active
parking func tion:
If the switch is pressed while mov­ing, the tractor decelerates to a
standstill. The tractor only starts to
drive again when the switch has
been released. This function
provides even more com­fort for all work which
requires frequent
short stops.
