Abstract Crop collecting apparatus comprising a platform (l) adapted for pivotal up and down movement about an axis that is located at the rear of the platform and extends transversely with respect to the direction of usual for- wards motion of the apparatus, the platform comprising a leading section (11) and a rear section (4) hinged together about an intermediate transverse axis (12) extending parallel to said rear axis, and actuation means (3) provided to pivot the platform about the rear axis so as to raise and lower the platform relative to the ground, support means (23) connected between the leading and rear sections (11, 4) of the platform (l) so as to support the weight of the leading section and allow it to pivot within a pre-set angular range, sensor means (29, 30) that senses when the leading section (11) reaches the limits of the pre-set angular range, and control means (33, 34, 35) provided to control operation of the actuation means (3) in a manner dependent upon operation of the sensor means (29, 30) so that in use the leading section (11) pivots within said pre-set angular range and the whole platform (1) is respectively raised and lowered when the leading section (11) reaches the upper and lower limits of said angular range of movement. The support means (23) may comprise a variable length strut and the leading section (11) may carry a skid (22) through which it engages the ground. Alternatively, the support means may comprise secondary actuation means (23) that operates together with the main actuation means (3). An automatic table height control system may be included.
