Gearbox controller for power shift transmission in working vehicle automatically selects defined starting gear ratio higher than lowest possible gear ratio every time it is switched on

摘要

The device has a gear selector (34) and a gearbox control unit (20) that outputs control signals to the power shift transmission (12) depending on the ratio selection to set up a corresponding transmission ratio. Every time the gearbox control unit is switched on it automatically selects a defined starting gear ratio that is higher than the lowest possible gear ratio.
