Abstract: The transmission comprises: an input shaft coupled to a prime mover of the tractor; an output shaft; a hydrostatic unit including a pump driven by the prime mover shaft and a motor driven by the pump; an epicyclic torque splitter unit, including a first and a second input shaft and a first and a second output shaft, the rotational speeds of the first and second output shafts varying, respectively, in a first and a second range adjacent to each other as the rotational speed of the first input shaft varies between a maximum value and a minimum value; a clutch unit, arranged to couple the output shaft of the transmission selectively to the first or second output shaft of the torque splitter unit to provide a pair of forward operating ranges, at high and low speed respectively; and a reversing unit, arranged to provide a reverse operating range.

Abstract: The transmission comprises: an input shaft t (IS) which can be coupled to a prime mover of the tractor and extends along a first direction (x1) aligned with the shaft of the prime mover and with a shaft (S1) of the power take-off of the tractor; an output shaft (OS); a hydrostatic unit (HU) including a pump (P) driven by the prime mover shaft and a motor (M) driven by the pump (P), wherein the pump and motor are positioned in line along a second direction (x2) spaced transversely downwards from the first direction (x1); an epicyclic torque splitter unit (TSU), positioned in line with the hydrostatic unit (HU) and including a first and a second input shaft (S3, S4), coupled to the motor (M) of the hydrostatic unit (HU) and to the prime mover, respectively, and at least a first and a second output shaft (S5, S6), the rotational speeds of the first and second output shafts (S5, S6) varying, respectively, in a first and a second range (VDI-VD2, VC1-VC2; VD1-VD2, VB1-VB2) adjacent to each other, at high speed and
