A drive and a method to control the drive of an agricultural vehicle, especially of a tractor, is described. The drive includes a combustion engine (M) and an infinitely variable electro-mechanical torque split gear. To avoid dissipation of reactive power the drive includes a shift gear (F) which has at least two input shafts (2, 3) each connected to at least one transmission step. Each of the at least two input shafts (2, 3) is in driving condition via a clutch (K1,K2) with a planetary gear (P1, P2) each with two inputs. The first input of each planetary gear (P1, P2) can be driven by a clutch (KV) from the driven shaft (1) of the combustion engine (M). The second input of each planetary gear (P1, P2) can be driven by a respective electric motor (S1, S2). At least one of the planetary gears (P1, P2) is designed to be locked-up. The drive can be operated in pure electric mode, in electro-mechanical mode or in pure mechanical mode.
