iTEC Functions—IVT (Infinitely Variable Transmission)™ Transmission

NOTE: For IVT Tractors when iTEC is executing, iTEC requests set speed adjustments. If speed lever or encoder is moved, set speeds will not execute.

B - Speed Band 2

IVT Set Speed: The current forward set speed (FSS1 or FSS2) can be changed up or down with the set speed adjuster, during Learn mode. Transmission ratio changes will be executed at the normal rate once the set speed has been changed.

During Learn mode, the set speed may be changed more than once. iTEC will record the time of the first set speed change in the sequence. If additional changes occur at less than two second intervals, they will be combined with the first into a single event. The direction of the set speed change (up or down), the speed control lever position (speed band 1 [A] or 2 [B]), and the final set speed are recorded. If drive lever goes into a non-forward position, set speed changes will not be saved, learned, or executed. The minimum set speed that can be saved is 0.8 km/h (0.5 mph). Changing the set speed or moving the lever during execution of a sequence will not cause iTEC to abort, but set speed changes will not be commanded for the remainder of the sequence.

When a set speed is changed by iTEC, the control unit will react just as if the operator changed the set speed, pushing other set speeds up or down as a result.
