Abstract

1420401 Rotary harrows C VAN DER LELY NV 16 Jan 1973 [24 Jan 1972] 2328/73 Heading A1B Soil working members 10 are arranged in two groups such that the two strips of soil worked by the groups adjoin or overlap each other, and drive is transmitted to the members 10 of each group by a common drive shaft 25 located midway between the groups as seen in plan, the common drive shaft 25 being connected to each gear box 15 which is common to its group and located between the ends of the group. The soil working members 10 of each group are supported by a beam 8, the beams 8 being pivoted by pins 5 to a frame 1 secured via a coupling member 30 to a tractor, so that the beams may be swung to the upright transport position (dashed lines). The shafts 9 of the members 10 carry meshing pinions 11 driven through gear-boxes 15, universal joints 15, and telescopic shafts 20, universal joints 21 and bevel gear box 23 from the common drive shaft 25. Pinions 26 on shaft 25 meshes with pinion 27 on a shaft 28 connected to the tractor power take-off; the pinions 26 and 27 are releasable via cover 29 to change the gear ratio. The beams 8 are swung upwardly about pins 5 and are held upright by means of rods 33 and the beams 8 are 'free to pivot about the pins 5 while harrowing. The depth of penetration of the tines 14 is determined by vertical adjustment of roller 32. In Fig. 3 (no't shown), the beams 8 are moved to the transport position by a doubleacting hydraulic piston-and-cylinder (36) connected to the tractor hydraulics, the piston rods being pivoted to arms (36A) secured to brackets 7. In Fig. 4 (not shown), the gear boxes 15 have their input shafts (37) directed rearwardly and connected via universal joints (38) and shafts to two stub shafts (39). Sprockets (40) carried by the stub shafts (39) are engaged by chains (41) engaging a twin sprocket (42) mounted on the common drive shaft 25. In Figs. 5 and 6 (not shown), the beams 8 are pivoted about vertical axes 46 corresponding to the shafts of the fifth or third soil working members 10 from the centre, so that the beams 8 may be swung horizontally to lie alongside or immediately behind the tractor wheels, locking means (not shown) being provided to hold the beams 8 in their working positions as well.
