MTZ checkpoint 2022

The MTZ 2022 gearbox is mechanical synchronized 24F+ 12R, three-range, six-speed, with a divider for up and down gears. Thus, in one range with 6 speeds, due to the divider, the number of gears doubles to 12. Taking into account two forward ranges and one reverse range, the tractor has 24 forward speeds and 12 reverse. Switching is carried out within the range from 1.86 to 39.7 km/h forward speed and from 2.6 to 18.4 km/h reverse.

Direct control of the gearbox is carried out by two separate bodies - the range selection lever and the speed selection lever. Reverse gears are only engaged when the reverse range is first engaged. This gearbox arrangement is convenient to operate when performing work in reverse mode.

Appearance of the MTZ 2022 gearbox

Switching from an increased gear to a lower one, or vice versa, is carried out by an electro-hydraulic drive using a control button on the gear shift lever, where the H switches the gearbox to a higher operating mode, the L – a lower mode. The compliance of the switched on stage is signaled by lamps on the lever handle. The green lamp corresponds to the inclusion of a lower stage, and the red lamp corresponds to a higher stage. The divider is switched only after first moving the gear shift lever to the neutral position.
