Using the shifting automatics

The tractor has two automatic gear-changing programs, Auto1 and Auto2.
With the Auto1 program, the Powershift gears are changed according to the
load and the engine speed.
With the Auto2 program, you can program the engine speed limits for shifting
the gears up and down.
In the Auto1 mode, the driving speed is controlled with the drive pedal or hand
throttle. The speed control method that gives the higher value overrides the other
method. The automatics handle the transmission and engine control, focusing on
optimal fuel economy when the engine load allows. The Powershift gear in use
has no effect on the driving speed. The Auto1 mode includes a kickdown
functionality, in which pressing the driving pedal fully down automatically shifts
the Powershift gear down and provides the best possible power instead of best
possible torque. However, the kickdown does not shift down from D range to C
range even if the C-D shifting automatics are in use.
NOTE: Different settings may limit the gears or engine speed available for use.
In the Auto2 mode, the shifting limits are locked to engine speed limits that the
driver has set. The Auto2 mode is used in certain tasks where the power take-off
is in use or in situations where the Auto1 mode would shift into an unsuitable
gear. When the engine speed cruise control is in use, also the Auto1 mode is
suitable for power take-off tasks.
