Abstract

The invention relates to an angular bevel gear drive (6), for driving, or for the drive of, agricultural implements. It comprises a basic housing (9) and bevel gears (13, 14) arranged therein. The shafts (10, 11) of one or several of the bevel gears (14) are associated with individual bearing units (15) into which a torque measuring device (12) is integrated, i.e. the torque may be measured both at the input and the output end. The torque measuring device (12) operates in a contact-free way and is arranged between the bearings (18, 19) of the bearing unit (15). By combining the drive with a torque measuring instrument (12) it is possible to make optimum use of the power of the tractor and the implement or individual functional areas of the implement.
