Abstract

1431630 Soil-cultivating implements C VAN DER LELY NV 9 April 1973 [12 April 1972] 31331/75 Divided out of 1422548 Heading A1B An implement comprising a plurality of soil-working members is sustained from the ground by a rotary supporting member 41A. This member is made up of a number of lengths of spring-steel rod 45 resiliently attached to a central tubular support 41 which has at each end a shaft 15. These shafts 15 rotate in bearings at the end of arms 9 which are adjustable in height relative to the main frame of the implement.
