These Vario Transmission emulators allow the transmission to use the engines full remapped power when needed, allowing performance closer aligned to a geared tractor at the top end. They dramatically reduce the drop off you get at the top end when climbing banks or working hard. Smaller tractors with the same engine and transmission as their more powerful counterparts have a lower max fuel usage limit set, the transmissions are built to cover a range of power outputs from different manufacturers and models with an upper limit of power easily coping with the extra. It’s only a small step at points where power is restricted by the limit. If you watch the litres per hour on any standard tractor the fuel will hit a limit it will not exceed it, this is usually most obvious under acceleration, at top speed when heading up hill or when working hard like baling on steeper terrain or ploughing in heavy ground. The Emulators will transform your tractor with Vario transmission making them hold on like a traditional transmission and not die off when full power is needed.
