FIELD: transport.
SUBSTANCE: row-crop caterpillar tractor comprises body, engine, gearbox, drive axle with main transmission reduction gear with its driven gear wheel engaged with caterpillar tracks via mechanism with hydraulic booster of body turn be caterpillar tracks. Aforesaid mechanism comprises a pair of planetary reduction gears with their sun gear wheels coupled with driven gear of main transmission. Other gear wheels are articulated with caterpillar tracks and hydraulic reversing engine communicated by oil lines with adjustable reversing pump operated at opposite direction of rotation of its shaft articulated with secondary shaft of gearbox. Steering wheel is articulated via hydraulic booster with operating pump displacement control element so that steering wheel central position corresponds to pump zero displacement.
EFFECT: improved maneuverability.
