A steering column (100) for a lawn and garden tractor or off-road vehicle includes an upper shaft (102, 202) with one end attached to a steering wheel (103) and the second end having a polygonal socket (110, 210), and a lower shaft (101, 201) that is non-parallel to the upper shaft (101, 201), with a first end connected to a steering control box (114), and a second end having a polygonal head (106, 206) inserted into the socket (110, 210) to impart torque between the upper and lower shafts (101, 201, 102, 202). The polygonal head (106, 206) has sides (108, 208) with curved profiles to allow misalignment between the upper and lower shafts (101, 201, 102, 202).
