Described is an agricultural equipment (10) which comprises:- a frame (11) configured to be hung on a tractor；- a power connector (12)；- a rotor shaft (13) fixed to the frame (11) in a rotatable manner with respect to a rotation axis (A)；- a transmission unit (14) fixed to the frame (11) and connected to the power connector (12), for receiving power, and to a median section of the rotor shaft (13) for actuating the latter.The transmission unit (14) comprises a head assembly (15) which has:- a casing (16)；- a first conical toothed wheel (17) which is rotatable about a primary axis (B)；- a conversion member (18) having a hub (19), a second conical toothed wheel (20) and a third toothed wheel (21), with straight teeth, both keyed onto the hub (19) which is fixed to the casing (16) in a rotatable manner according to a secondary axis (C). Moreover, the transmission unit (14) comprises a lower unit (21) which has a fourth toothed wheel (22), with straight teeth, which lies on a transmission plane (D)； the primary axis (B) and the third toothed wheel (21) lie on the transmission plane (D).The casing (16) and the conversion member (18) are configured for being assembled in a first configuration or in a second configuration where, following a rotation in a direction of actuation (E) of the first toothed wheel (17), in the first configuration the conversion member (18) actuates the fourth toothed wheel (22) in a first direction of rotation (F) and, in the second configuration, the conversion member (18) actuates the fourth toothed wheel (22) in a second direction of rotation (G) which is opposite to the first direction of rotation (F).
