Landini 4 Series

Mechanical Speed Four or electroidraulic Power Four transmission (HI-LO Powershift)

The 4 Series tractors feature a versatile modular transmission (Speed Four) with four synchronized gears in three ranges offering 12 speeds forward and 12 reverse. The basic gearbox is offered in a 30 km/h configuration on the 2WD models and with the addition of a creep gearbox option provides up to 16 +16 speeds. On the 4WD version, the basic gearbox can be combined with the Power Four transmission, a hydraulic Hi-Lo gear splitter that allows the operator to either increase or reduce the selected speed by up to 18%, thereby obtaining 24 speeds forward and reverse at 40 Km/h. Available with this package is an Eco Forty mode that allows 40 km/h to be reached at 1900 rpm, resulting in increased fuel economy and lower noise during road transport. A creep speed unit with 32 forward and 32 reverse gears and speeds as low as 300 m/h is available as an option. The transmission incorporates as standard a synchro shuttle or, optionally, an electro-hydraulic power shuttle with control lever adjacent to the steering wheel. A shuttle modulation control (potentiometer) allows the power shuttle response to be adjusted to suit implement used and soil conditions. The Power Four transmission also features a declutch control (orange button integrated into the gearshift lever) which, used in conjunction with the reverse power shuttle, allows the operator to easily shift through the gears and change from forward to reverse without using the clutch pedal.
