956,004. Haymaking machines. C. VAN DER LELY N.V. Oct. 11, 1960 [Oct. 23, 1959], No. 34808/60. Heading A1F. A side-delivery raking arrangement comprises two frames 1, 27 coupled together and having mountings 7, 29 for rake-wheels 3-13, the total number of rake-wheels being sufficient to fill all the mountings on one frame 1, there being two possible working positions, in the first of which the first frame 1 carries all the rake-wheels and in the second position at least one of the rake-wheels is moved to the second frame 27, the arrangement of the coupling members 14, 20, 31 on both frames being such that either frame can be coupled to a tractor 23 independently of the other. As shown, three rake-wheels 8, 9, 13 can be moved to the second frame 27 which is mounted on a single ground-wheel 46 and is coupled by a universal joint 31 to a bracket 24 on the first frame. The joint 31 comprises non-intersecting vertical and horizontal pivots 34, 36 so that the front end of the frame 27 cannot move vertically. A bracket 48 permits the coupling of a third frame when desired. The frame 1 is a deformable parallelogram having ground wheels 14, 15, 16 of which the wheel 16 is normally co-axial with the wheel 46 and the wheel 14 is secured to a rod 18 which is coupled to the tractor by a drawbar 19 having vertical and horizontal pivots 20A, 18A at its ends. The rake-wheels on the frame 1 are carried by cross-bars 4 and can be angled to the line of draught by deforming the parallelogram, a locking sector 114 being provided. In a modification, (Fig. 3, not shown) the frame 27 is coupled directly to the tractor draughtbeam 22 by a pair of forked members 34 spaced apart along the portion 30 of the frame. The draw-bar 19 is then coupled to a bracket similar to the member 48 but more rearwardly located.
