Stepless speed control
Dyna-VT has two infinitely variable
speed ranges, 0-28 km/h for field
applications and 0-50 km/h* for
transport applications.
To start work, simply move the
left-hand Power Control lever into
‘forward’ or ‘reverse’ direction then
push the armrest-mounted
Dyna-VT lever. The further you
push the lever, the faster you
accelerate. No shifting of gears. No
jerks. No breaks in traction or power;
just infinite speed control from
‘supercreep’ to high transport
speeds!
To slow down, simply pull the lever
back. When you’ve reached your
chosen speed, just release the lever.
Left-hand Power Control
If you prefer left-hand control, the
Power Control lever adjusts ground
speed in a similar way, and also
gives convenient, left-hand control of
forward/reverse shuttle (see page 12
for more details).

Dyna-VT gives infinitely variable speed control with optimum
power, engine speed and fuel efficiency, resulting in significant
gains in output and productivity. And with the proven, familiar ‘MF
family’ control layout, operation is straightforward and intuitive.
Smooth forward/reverse shuttle
Moving the Power Control lever
from forward to reverse position
gives an incredibly smooth power
shuttle, with the added benefit
of being able to pre-set the
relationship between forward and
reverse speed.
Pre-set speed control
Travel speed and rate of
acceleration can also be pre-set
and memorised within each of two
ranges - ‘SV1’ and ‘SV2’.
The memorised speed acts as
a cruise control to maintain a
specified speed. It is activated by
pressing the SV1 or SV2 button
located conveniently in the armrest
and can be adjusted, during work,
simply by turning the appropriate
SV1/SV2 rotary switch in the
binnacle on the right-hand console.
The ‘Supervisor’
Supervisor optimises the
relationship between engine
load and travel speed and, in
conjunction with SV1/SV2 speed
control, can significantly increase
productivity in all conditions.
Supervisor reduces forward
speed when load becomes
excessive, as defined by the rotary
control setting, and SV1/SV2 will
accelerate the tractor back to the
desired forward speed as load
decreases.
As this process is happening
smoothly, continuously and
automatically, maximum output
and fuel economy are easily
maintained.
