Abstract

671,908. Agricultural implements. ROHR, E., (trading as MASCHINENFABRIK E. ROHR). Sept. 12, 1950 [Sept. 12, 1949; Oct. 29, 1949], No. 22466/50. Class 6(i) A tractor-mounted harrow having Power-driven, oscillating, prongs 5 is characterised in that the prongs are mounted on cranks pivoted to the main frame 1 of the harrow and reciprocated by a rod 14 reciprocated by the tractor. The cranks may have three arms (as shown), or two arms, one of the arms 2 being pivoted to the oscillating rod 14. The prongs 5 are adjustably bolted to the arms 3 and 4 of the cranks. The harrow is mounted similarly to a tractor-mower and uses the same driving mechanism.
